Summer Guide

Welcome to your park!

Summer is a magical time at Joshua Tree 

National Park. The traffic slows down, the 

temperatures rise, and peace comes to the 

desert.

I just want to take a second and welcome 

you to your national park. Over the last 80 

years, millions of people have come from 

around the globe to enjoy the wonders of 

JoshuaTree. This last year, over 2 million 

people came to see the diversity of wildlife 

and plants that make this such aspectacular place.

I need your help to protect the magic that 

is Joshua Tree. Help us keep the wildlife 

wild by not feeding the animals. When 

you’re hiking along the trail and come 

across someone’s litter, pick it up. If you 

see folks doing things that are not good 

for the park, take some time out and call 

a ranger.

We’re here both to serve you and to protect this park.

Have a safe and wonderful time at your 

national Park.

The Hot Season

Being an ectotherm is a great strategy for a desert animal 

because, overall, food is scarce in the desert. Without 

a constant need to take in food just to maintain body 

temperature, reptiles are able to burrow underground 

and go dormant to escape the fatal, freezing cold of 

winter. They can go for months without eating or 

even drinking. On the other extreme, while hot is 

good for an ectotherm, too hot is still too hot! Even 

the desert-adapted reptiles have their limits.

Human-caused climate change has already made 

the desert southwest hotter and drier than it used 

to be, and these changes are expected to continue. 

Because reptiles are so sensitive to external 

temperature, some species will likely suffer.

Recent research by Dr. Cameron Barrows, an ecologist 

at the University of California Riverside, suggests that 

some lizard species present in Joshua Tree National Park 

today will probably vanish from the park. Blainville’s 

horned lizards (formerly known as coast horned lizards) 

and western fence lizards living in Joshua Tree, for 

example, are already at the edge of the range of conditions 

they can tolerate. Increasing temperatures or changing 

precipitation patterns may push them out of the area.

Climate change doesn’t just affect reptiles. The range 

of the Joshua tree itself is expected to shrink, while 

pinyon pines may vanish from the park altogether. 

Mountain quail, which in Joshua Tree are found mainly 

in association with pinyon-juniper woodlands, were 

abundant in the 1950s but are now scarce in the park. 

Will they continue to survive here as the world warms?

Climate change threatens the integrity of national 

parks. For almost a hundred years, the National Park 

Service has protected America’s most special places 

for future generations to experience. Simply trying 

to preserve natural processes is no longer enough.

So look for reptiles on your summer visit. Appreciate the 

adaptations that make them so different from us, and so well 

suited for desert life. And reflect on how these fascinating 

creatures can best be protected for an uncertain future.

a t m i d d a y, t h e s u n b e a t s r e l e n t l e s s ly d o w n o n a 

still and silent desert landscape. Few animals stir as the air 

temperature soars over a hundred degrees. Wildlife escape 

the fierce heat of the sun by sheltering underground or in the 

shade. People, too, seek comfort in cooler places, reveling 

in the icy blast of air conditioned cars and buildings.

When the heat of the summer afternoon yields 

to the cooler temperatures of evening, little feet 

begin to scurry across the sandy soil. The desert 

life that slumbered until dusk begins to wake.

Not all animals slept the day away, though. On all 

but the most scorching days, lizards, snakes, and 

desert tortoises may be out and about when few other 

animals are active. How can reptiles stand the heat?

Reptiles are sometimes referred to as “cold-blooded,” 

but that term is misleading: reptile blood is not cold all 

the time. A more accurate word for describing reptiles 

is “ectotherm,” meaning “outer heat.” Reptiles don’t 

generate their own body heat using energy from food, as we 

mammals do. Instead, they absorb heat from the external 

environment to regulate their internal body temperature. 

Cold winters make reptiles sluggish and unresponsive. The 

heat of the summer sun spurs them to greater activity.

Summer Safety

Summer is traditionally the quiet season in 

Joshua Tree, but it is getting busier every year as 

visitors discover the sense of wonder that comes 

with experiencing the desert in the hot season. 

Learn about how to stay safe and enjoy your 

Joshua Tree visit to the fullest on pp. 2-3.

Map & Hiking

Orient yourself to Joshua Tree using the park 

map in the centerfold of this newspaper. On 

the same page, find suggestions for hiking 

trails. Whether you are interested in short, 

easy walks or a tough, full-day hike, you’ll find 

inspiration on pages pp. 4-5.

Ranger Programs

Enrich your experience of Joshua Tree National 

Park by joining a friendly, knowledgeable 

ranger for a guided walk, patio talk, or evening 

program. Most ranger-led activities (except 

tours of Historic Keys Ranch) are free and do 

not require advance signup. See p. 8.

Blainville’s horned lizard could disappear from Joshua 

Tree National Park as the climate continues to warm.

Joshua Tree National Park

The official newspaper
CELL PHONES ARE UNRELIABLE

Most of Joshua Tree National 

Park is remote wilderness and 

there is no cell coverage. Do 

not count on your phone for 

navigation or in case of emergency. 

IN CASE OF EMERGENCY

Emergency phones are 

found at two locations:

• Indian Cove Ranger Station

• Intersection Rock parking area near 

Hidden Valley Campground

If you are in an area with cell service 

and you have an emergency, call 911

or 909-383-5651 for assistance.

PREVENT BITES & STINGS

Joshua Tree is home to 

seven species of 

rattlesnakes, as well as 

venomous scorpions and spiders. 

These animals are not out to get you. 

You can avoid problems by paying 

attention to your surroundings. Never 

step or reach into places you cannot 

see. Use a flashlight or headlamp at 

night. Campers, check your shoes 

and bedding for critters before use. 

In summer, thirsty bees congregate 

around any source of moisture they 

detect, including human perspiration 

and car AC systems. Stay calm around 

bees and do not swat at them. Keep 

drinks and food inside your vehicle.

Be generous in applying sunscreen, and 

reapply often. The desert sun is strong.

Safety: What You Need to Know

We want your trip to Joshua Tree to 

be safe and enjoyable. Ultimately, 

your safety is your responsibility. This 

information will help you prepare.

BRING WATER WITH YOU

Water is available at only 

a few locations around 

the edges of the park:

• Oasis Visitor Center in Twentynine Palms

• Black Rock Campground

• Cottonwood Campground

• West Entrance (no RV water access)

• Indian Cove Ranger Station (no RV 

water access)

STAY HYDRATED & EAT SALTY SNACKS

We recommend drinking a 

minimum of one gallon (about 4 

liters) of water per person, per day. 

You will need more fluids if you are 

active: vigorous hiking, cycling, 

or climbing can causes you to lose 

water and salts at a rate of 1 1/2 quarts 

per hour. Replace these fluids and 

electrolytes by drinking water or sports 

drinks and consuming salty foods.

PROTECT YOURSELF FROM 

HEAT & SUN

Expect high daytime 

temperatures, intense 

sunlight, and low humidity. Wear 

loose-fitting, light-colored clothing 

and a wide-brimmed hat. Apply 

sunscreen to all exposed skin. Protect 

your eyes by wearing sunglasses.

GIVE WILDLIFE A BRAKE

Park roads are narrow 

and winding, and

some areas are often 

congested. Obey posted speed limits. 

The maximum speed in the park is 45 

mph (73 kph), and in many locations 

the speed limit is lower. Driving 

slowly and cautiously helps protect 

park wildlife. If you want to stop to 

view animals or scenery, please use a 

pullout and get completely out of the 

travel lanes to prevent accidents.

DON’T TRUST GPS FOR DRIVING DIRECTIONS

In the desert, some GPS units or 

navigation apps may try to direct you to 

roads that are unsafe for your vehicle. 

For safety, refer to the park map for 

navigation, or check with a ranger. 

TURN AROUND, DON’T DROWN

Flash floods occur when summer 

thunderstorms pour large amounts 

of rain in a short time. Avoid canyons 

and washes during rainstorms 

and be prepared to move to higher 

ground. While driving, be alert for 

water running across the road. Wait 

for floodwaters to subside rather 

than trying to drive through.

STAY OUT, STAY ALIVE

Many old mine sites exist within the 

park. If you choose to visit them, use 

extreme caution, appreciating them 

from a safe distance. Never enter old 

mine tunnels, shafts, or fenced areas.

Joshua Tree National Park preserves 

and protects the scenic, natural, and 

cultural resources representative of the 

Colorado and Mojave Deserts’ rich 

biological and geological diversity, cultural 

history, wilderness, recreational values, 

and outstanding opportunities for 

education and scientific study.

EXPERIENCE YOUR AMERICATM

National Park Service

U.S. Department of the Interior

Never reach into rock crevices or onto ledges 

where you can’t see. 

Many historic mine sites exist within Joshua 

Tree National Park. Admire, but do not enter.

Watch wildlife respectfully

We recommend staying at least 25 yards (23 m) from wildlife. If an animal reacts 

to your presence by changing its behavior, you are too close—even if you are more 

than 25 yards from it. Move quietly away to give the animal space. Remember, the 

park is home for wild animals. We are just visitors here.

Never feed any wild animals

Consuming human food is unhealthy for wildlife and may encourage aggressive 

behavior. Coyotes, squirrels, ravens, and other animals should be left alone to rely 

on natural sources of food. All food, trash, scented products, and cooking tools 

must be stored securely in a vehicle or hard-sided container. 

Travel responsibly with your pet

Pets are allowed in the park, but their activities are restricted. Pets must be on a 

leash at all times. They cannot go more than 100 feet (30 m) from a road, picnic 

area, or campground. Pets are not allowed on hiking trails. Owners must never 

leave a pet unattended or tied to an object. Bag and dispose of pet waste.

No drones or remote controlled vehicles

Remote controlled vehicles, including aircraft and rockcrawlers, are prohibited in 

Joshua Tree National Park. Drones and other remotely-operated craft can disturb 

wildlife and disrupt the visitor experience.

Campfires

Campfires are allowed only in designated fire rings or grills that are found in park 

campgrounds and picnic areas. Campfires are not allowed in the backcountry. 

Bring your own firewood and extra water to douse your campfire. Do not use park 

vegetation, living or dead, for fuel.

Rules and Regulations

No collecting park resources, including living or dead vegetation

It is the mission of the National Park Service to preserve all natural and cultural 

resources unimpaired for future generations. Please leave everything in the park 

as it is for others to enjoy. Do not destroy, deface, dig, collect, or otherwise 

disturb any park resources including plants or animals (whether they are dead or 

alive), rocks, fossils, or artifacts.

Rock climbing

Climbers may replace existing bolts if they are unsafe. New bolts may be placed in 

non-wilderness areas if in accordance with the bolting checklist, available on the 

park website. Bolting in wilderness requires a permit. Hand drills only.

All motor vehicles and bicycles must stay on roads

The desert environment is more fragile than it may look. The ruts and scars left by 

vehicles illegally taken off-road can last for years or even decades. Red and green 

sticker dirt bikes, ATVs, and UTVs are prohibited in all areas of the park.

Watch for tortoises

The desert tortoise is a threatened species that often dies from being hit by cars. 

Be very watchful and drive carefully in the park: small tortoises on the road look a 

lot like rocks. Be especially mindful during monsoon season, when tortoises often 

come to roads to drink from puddles. Tortoises also sometimes go under cars to 

get out of the strong summer sun. Check under your vehicle before driving. 

Firearms and weapons

Firearms may be possessed in accordance with California state and federal laws. 

However, they may not be discharged in the park. Fireworks, traps, bows,

BB guns, paintball guns, and slingshots are not allowed in the park.

No!

2 Joshua Tree Guide
Th e d e s e r t i s a t i t s b e s t w h e n

viewed up close and at a slow pace. 

From a whizzing car, the landscape 

may at first appear bleak or drab. 

Closer examination, though, reveals 

a fascinating variety of plants 

and animals. Rocks sculpted by 

weather and time contrast with the 

brilliant blue of the desert sky.

Joshua Tree National Park has 

endless opportunities for exploration 

and discovery. Begin your trip at a 

park visitor center, where a ranger 

will be happy to answer your 

questions and get you oriented. 

IF YOU HAVE A FEW HOURS:

• Plan to drive between the West Entrance 

and North Entrance of the park to see 

the Joshua trees and boulder fields that 

make this park famous. 

• Drive to Keys View for a lovely vista of 

the Coachella Valley. On days with little 

air pollution, you may be able to see 

beyond the shining Salton Sea to Signal 

Mountain in Mexico.

• Take a short walk on one or two of the 

park’s nature trails (p. 4-5) to get an upclose look at desert scenery and plants.

• Kids of all ages are invited to participate 

in our Junior Ranger program (p. 8).

IF YOU HAVE AN ENTIRE DAY:

• Hike one or two of the park’s longer 

trails (pp. 4-5). In summer, it’s best to 

plan physical activity for early mornings 

and evenings, when temperatures are 

cooler.

• Attend a ranger-led activity like a patio 

talk, guided walk, or evening program 

(p. 8). If you’ll be visiting on a weekend, 

consider calling ahead to make a 

reservation for a Keys Ranch tour (fee).

• Drive through both the Mojave Desert 

and the Colorado Desert by going from 

the West Entrance to the South Entrance. 

See where Joshua trees grow in the 

Mojave, in the western half of the park, 

and observe the different vegetation 

of the Colorado in the lower-elevation 

Pinto Basin and Cottonwood areas. 

IF YOU HAVE MORE THAN ONE DAY:

• Spend the night in one of our 

campgrounds (p. 6). If you have the 

right gear, experience, and fitness level, 

consider an overnight backcountry trip.

• Explore the longer hiking trails around 

Black Rock or Cottonwood (p. 4-5).

• If you have a mountain bike or highclearance vehicle, consider exploring a 

backcountry road (p. 6) to experience 

parts of the park that most visitors 

never see.

Summer in the desert poses challenges for 

travelers today, just as it did in 1905 when 

miner Matt Riley “died of thirst” (right) while 

trying to walk 25 miles in temperatures of 

114° F (45.6°C)—with only one canteen of 

water. Don’t fall victim to the same fate! 

Travel prepared to survive.

Always have water with you.

When driving in hot weather, have with you 

in your vehicle at least two gallons (about 

8 liters) of water per person, per day. If you 

leave your vehicle, carry water with you.

Fill your gas tank and be sure your 

vehicle is in good condition before 

driving into the park.

There is no gas available in Joshua Tree 

National Park. The park is a big place, so 

start your day with a full tank of gas. Before 

entering the park, check your tire pressure 

and fluid levels, especially coolant. 

What if your vehicle breaks down?

Stay with it until help comes. Do not try to 

walk for help during the heat of the day.

Notify a friend or family member of 

your itinerary.

Let someone know your intended route 

and return time. Check in by phone when 

you are safely back. If you miss your 

check-in, your contact should notify park 

rangers by calling the Federal Interagency 

Communication Center at 909-383-5651.

l e av e j o s h u a t r e e p r i s t i n e f o r

those who visit the park after you. 

Learn and practice the seven Leave 

No Trace principles.

PLAN AHEAD & PREPARE

• Know the regulations and special 

concerns for the area you’ll visit.

• Prepare for extreme weather, hazards, 

and emergencies.

• Schedule your trip to avoid times of high 

use.

• Visit in small groups when possible. 

Consider splitting larger groups into 

smaller groups.

• Repackage food to minimize waste.

• Use a map and compass. Do not set up 

rock cairns or other physical markers.

TRAVEL & CAMP ON DURABLE SURFACES

• Durable surfaces include established 

trails and campsites, rock, and gravel.

• No camping in rock shelters or caves.

• Allow wildlife free access to scarce desert 

water sources. Do not camp nearby.

• Good campsites are found, not made. 

Altering a site is not necessary.

• In popular areas, concentrate use on 

existing trails and campsites. 

• In pristine areas, disperse use to prevent 

the creation of campsites and trails. 

Avoid places where impacts are just 

beginning.

DISPOSE OF WASTE PROPERLY

• Pack it in, pack it out. Inspect your 

campsite and rest areas for trash or 

spilled foods. Pack out all trash, leftover 

food and litter.

• Deposit solid human waste in catholes 

dug 6 to 8 inches deep, at least 200 feet 

from water, camp, and trails. Cover and 

disguise the cathole when finished.

• Pack out toilet paper and hygiene 

products. These items do not break 

down in the arid desert environment, 

even when buried.

LEAVE WHAT YOU FIND

• Preserve the past: examine, but do not 

touch, cultural or historic structures and 

artifacts.

• Leave rocks, plants and other natural 

objects as you find them.

• Avoid introducing or transporting 

non-native species.

• Do not build structures, furniture, or dig 

trenches.

MINIMIZE CAMPFIRE IMPACTS

• Campfires are allowed only in established metal fire rings in campgrounds 

and picnic areas with fire grates. All 

wood must be brought in from outside 

the park—no collecting.

• Keep your fire small. Put it out 

completely before you leave your site.

• No campfires in the backcountry. Use a 

lightweight stove for cooking.

RESPECT WILDLIFE

• Observe wildlife from a distance. Do not 

follow or approach animals.

• Never feed animals. Feeding wildlife 

damages their health, alters natural 

behaviors, and exposes them to danger.

• Protect wildlife and your food by storing 

rations and trash securely.

• Avoid wildlife during sensitive times: 

mating, nesting, raising young, or harsh 

weather conditions.

BE CONSIDERATE OF OTHER VISITORS

• Respect other visitors and protect the 

quality of their experience.

• Be courteous. Yield to other users on the 

trail. Hikers traveling uphill have rightof-way.

• Step to the downhill side of the trail 

when encountering pack stock.

• Take breaks and camp away from trails 

and other visitors.

• Let nature’s sounds prevail. Avoid loud 

voices and noises. Respect campground 

quiet hours.

recreation impacts and protect Joshua 

Tree’s wildlands for the future. Talk

Watch for signs of heat-related illness 

in yourself and others.

Headaches are often a sign of dehydration. 

Prevent them by drinking water. If you feel 

dizzy or nauseated, or if you experience muscle 

cramps, get out of the sun immediately and 

drink water or sports drinks. Dampen clothing 

to lower body temperature. If symptoms 

are severe or persist, seek medical attention 

immediately! Heat-related illnesses can be fatal. 

Be alert for symptoms in others.

Bring a desert first aid kit.

Many desert plants are armored with sharp 

spines. Suggested items for a desert first aid kit 

include tweezers, safety pins, bandages of various sizes, antibiotic ointment, antiseptic towelettes, wound closure strips, moleskin or duct 

tape for blisters, compression bandage, ibuprofen, aspirin, antihistamine tablets, extra food 

and salty snacks, and an emergency blanket.

For outdoor activities, know your skill 

level. Do not take chances. 

Enjoy the Joshua Tree desert safely!

Wilderness

Congress has designated

nearly 558,000 acres of

Joshua Tree National Park

as wilderness. Most of the

park away from road

corridors is wilderness. If

you plan to venture into

these areas, you must be

familiar with special rules

and regulations governing

wilderness use.

Transition Zone

In this ecological melting

pot, two great deserts,

the Mojave and Colorado,

blend together in a vibrant

landscape featuring plants

and animals representative

of both.

Equestrian Use

Horseback riding is a popular way to experience the park. The Backcountry 

and Wilderness Management Plan provides for 253 miles of equestrian trails 

and trail corridors that traverse open lands, canyon bottoms, and dry washes. 

Many riding trails are already open, clearly marked, and ready to be enjoyed. 

Other trails are in various states of development. Trail maps for the west 

entrance area and for the Black Rock Canyon area are available.

Stock use is limited to horses and mules and is restricted to designated equestrian trails and corridors, open dirt roads, and shoulders of paved roads. 

Riders should travel single file to reduce damage to soil and vegetation. Stock 

animals are not permitted within 1⁄4 mile of any natural or constructed water 

source. Horses and other stock are not permitted on nature trails, in the Wonderland of Rocks, in campgrounds, in picnic areas, or at visitor centers.

6 Joshua Tree Guide
Joshua Tree’s Boulders

Th e b o u l d e r s a n d r o c k

formations of Joshua Tree National 

Park define the park landscape. The 

rocks catch the eye of climbers, 

photographers, hikers, and motorists. 

Most everyone asks, “What are they?” 

“Where did they come from?” or 

“What’s with all the strange shapes?”

WHAT ARE THEY?

Many visitors think the rocks look 

like layers of sandstone, but they 

are actually a kind of granite, not 

unlike the rock commonly used for 

countertops. Granites are igneous in 

origin, meaning they formed when 

hot, molten fluids within the earth’s 

crust gradually cooled into hard rock. 

Most granites in the park are a 

particular type called “monzogranite.” 

Joshua Tree’s monzogranites 

solidified beneath the surface of the 

Earth starting about 245 million 

years ago, with the youngest rocks 

formed over 100 million years ago.

WHERE DID THEY COME FROM?

About 250 million years ago—

before the dinosaurs came to 

dominate the planet—the thick 

North American plate began riding 

over the thinner Pacific Plate. The 

water-rich oceanic plate was forced 

under the continent at an angle.

Water at depth, where temperatures are 

extremely hot, helped to melt the rock 

into granitic magma. It was hot, liquid, 

and lightweight, and was able to ooze 

upward along deep-seated cracks in the 

crust that had been fractured by the 

fierce crunching of the charging plates.

The liquid granite couldn’t force itself 

all the way up to the surface, so the 

granite stalled and formed huge, ballshaped masses within the ancient rock. 

Over a long period of time, the great 

blobs of granite cooled and hardened.

The ancient rock, called gneiss 

(pronounced “nice”), began to erode. 

Over millions of years, the gneiss 

has completely vanished from the 

surface in most of the park. The 

gneiss, dark in color, does remain 

exposed on mountain tops. Younger 

and lighter-colored monzogranites 

are seen in the valley bottoms.

WHAT’S WITH ALL THE STRANGE SHAPES?

In many places in the park, the 

boulders appear as if some gigantic 

child piled them up. Some boulders 

have carved faces, are shaped like 

animals, or take other fanciful forms.

Cracks in the rocks and water

are the keys to the appearance 

of our rocks today.

Horizontal stresses from the collision 

of tectonic plates created sets of 

parallel, vertical fractures within 

the buried rock. Later, mountain 

building pushed the rocks upward 

to form sets of X-shaped cracks 

standing at angles in the granite. 

All the fractures were avenues for 

rainwater to seep downward through 

the rocks to etch and shape and round 

the originally angular blocks into the 

varied forms seen today in the park.

During the last Ice Age, the climate 

was cooler and wetter; rainwater was 

abundant. Much of the water etching 

occurred then. No glaciers existed 

this far south at these elevations, so 

glaciers were not a factor in making 

the landscape we see today.

by Dar Spearing, Ph.D.

1. Parallel sets of fractures formed in the hard 

monzogranite while it was still underground. 

Water began infiltrating along the cracks.

2. The edges and corners of buried rock blocks 

became rounded as water broke the rock down 

into smaller particles.

3. Erosion carried away the small particles of 

broken-down rock, exposing the rounded rocks 

that had once been beneath the surface.
