Visitors who explore away from the main highways should take the following precautions. Go with another vehicle, or leave your travel plans with someone who will initiate a search if you fail to return when scheduled. Carry a first aid kit, plenty of extra food, water and basic emergency tools and supplies for your vehicle. A minimum of one gallon of water per person per day is recommended. Take clothing, a hat, and shoes appropriate for the weather and planned activities.
Sunscreen lotions are essential.
The high-desert sun is intense in any season. During warm weather, avoid strenuous activities that might lead to heat exhaustion. Drink plenty of water. Do not drink untreated water except in emergencies as it may be contaminated or carry disease-causing organisms. Do not camp in washes or drainages that might become flooded following rain, and avoid driving or hiking in narrow canyons during inclement weather.
