# Deserts

Deserts are defined by dry weather conditions and low precipitation. They can be found throughout the world, and often represent some of the last remaining wilderness areas.

## Understand

Deserts are generally considered to be regions that receive less than 10 in (250 mm) of rain per year while also south of the Arctic Circle. Trees generally need good water supplies and are therefore rarely found in deserts, except at oases. Although grasses can be found in some deserts such as high-elevation deserts, they are not common in low-lying deserts.
The stereotypical desert is hot, but not all deserts are. Polar regions, despite the snow that covers these areas, are often very dry; the same is the case with Mongolia and China's desert regions. Mountain deserts are often cold, too. Even stereotypical hot deserts can get cold at night, partly due to the lack of moisture in the air.

## Destinations
### Africa

* -23221 Kalahari Desert. It's in the southern part of the continent. (updated Nov 2018)
* 23.07972212.6122222 Sahara. Dominates the northern part of Africa, reaching the Sahel in the south, which receives wet and dry seasons. (updated Nov 2018)
* -24.75194415.2763893 Namib Desert. A desert located on the Atlantic coast of South Africa, Namibia and Angola. Its coastal location and latitude make it one of the few deserts in which you can see penguins. (updated Jun 2020)

### Antarctica

The continent is considered a desert, with minimal rainfall along coastal regions and even less in the interior.

### Asia

* 18.26722242.3680564 Arabian Desert. (updated Nov 2018)
* 42.59103.435 Gobi desert. Known for being cold. (updated Nov 2018)
* 32536 Dasht-e Lut and Dasht-e Kavir (Central Iran). Sand, rock and salt.
* 31.735.37 Judaean Desert. Also see Hiking in the Judaean Desert. (updated Nov 2018)
* 30.534.9166678 Negev. (updated Nov 2018)
* 40839 Taklimakan Desert (Xinjiang). One of the deserts on the Silk road

### Australia

Australia as a landmass is mostly made up of deserts or semi-deserts, with relatively narrow fertile areas along coastal areas and the south west region. The largest individual desert is the -29.57128.5910 Great Victoria Desert.

### Europe

The closest thing to a desert on the European mainland is the semiarid region in inner and southern Spain. The interior of Iceland, a cold, barren area, is characterized as desert.

### North America

A lot of the dry parts of North America are in northern Mexico and the southwestern United States, just over a mountain range or two away from the coast. As you go north into the Great Basin, the elevation increases and you enter high-elevation desert.
* 30.3-105.911 Chihuahuan Desert (includes the White Sands) (Northern Mexico, Southwestern United States). (updated Aug 2024)
* 36.2484-116.839412 Death Valley National Park (Southeastern California). This national park is the location of North America's lowest point, Badwater (although it is surrounded by mountain ranges). Death Valley is among the hottest locations on Earth, and while it is also very dry, rain that does come can be heavy. There are areas of sand dunes, although at Badwater it is very flat and you can easily see across to the mountain ranges on the sides of Death Valley. (updated Nov 2018)
* The 35.03-116.084113 Mojave Desert merges into the Baja Californian desert at its southern extent.
* 32.26-112.9314 Sonoran Desert (Northern Mexico, Southwestern United States). (updated Aug 2024)

### South America

* -24.5-69.2515 Atacama Desert. This desert is famous for being extremely dry, even when compared to some other deserts. It is almost as dry as the McMurdo Dry Valleys in Antarctica, considered the driest place on Earth. (updated Nov 2018)

## Stay healthy

Even if water is not a severe threat to your life, you can still get dehydrated. Only go hiking in deserts during the wintertime unless you're in a cold desert like the Gobi, since dehydration (especially severe cases that are related to hot weather) may not kill you, but is still not healthy. The same also goes for food and any other supplies which you need in any situation.

## Stay safe

    Main article: Arid region safety
The most obvious risk is not getting enough water—always bring extra. Another problem is getting lost or stuck, as deserts are sparsely populated and help may be hard to find. See Arid region safety for details.
Despite the inhospitable environment, deserts are home to many types of dangerous animals, including venomous snakes and scorpions.
Deserts are rarely well-policed, and can be home to criminal or terrorist groups. Always check the relevant travel advisories.
In the heat of the day, travelers can experience mirages that give the illusion of water (or other things). These can be dangerous if the traveler pursue the mirage, wasting precious energy and remaining water.
Even the hottest of deserts can become extremely cold at night. Hypothermia is a real risk without warm clothing.
