Quick answer: in the desert, water is the first priority. Desert parks such as Death Valley National Park advise drinking at least one gallon (about 4 liters) of water per person per day, and more when hiking or in heat, so bring all you need plus extra in the vehicle. Camp in fall, winter or spring when you can, avoid the midday sun, and never camp in a dry wash or slot canyon, where the National Weather Service warns flash floods can arrive from storms miles away. Expect big temperature swings, strong wind and cold nights. Stay on durable surfaces to protect fragile biological soil crust.
Deserts offer some of the most spectacular camping in North America: dark skies full of stars, sculpted rock, blooming cactus in spring and wide-open quiet. They also punish poor planning faster than almost any other environment. Water sources are rare, shade is limited and the weather can swing from scorching to freezing in a single day.
This guide covers what to plan for before and during a desert camping trip. It is part of our camping safety guide, which covers weather, wildlife, fire and first aid across all environments.

When to Go
Timing matters more in the desert than almost anywhere else. In the low deserts of the American Southwest, summer daytime temperatures are often dangerous. Death Valley National Park, which the NPS notes holds the record for the highest air temperature recorded on Earth (134°F in 1913), warns visitors that summer heat can be deadly and recommends limiting summer activity to short walks near the road and air-conditioned shelter.
For most campers, the best desert seasons are:
- Fall: warm days, cool nights and fewer crowds after summer.
- Winter: mild days in the low deserts, but nights can drop below freezing and high deserts may get snow.
- Spring: popular for wildflowers and comfortable temperatures, but campgrounds fill quickly.
High deserts, such as parts of Utah, Nevada and the Colorado Plateau, are cooler than low deserts but can be very cold in winter. Check the specific park’s seasonal page.
Water: Bring More Than You Think
Many desert campgrounds have no drinking water, and natural sources are unreliable or nonexistent. The NPS at Death Valley advises drinking at least one gallon of water per person per day, and more when active or in heat. Other desert parks give similar guidance.
How to plan your water
- Count people and days. Multiply one gallon per person per day as a baseline, then add more for hiking, cooking and washing.
- Add a reserve. Keep several extra gallons in the vehicle in case of a breakdown or delay.
- Carry water on every hike, even short ones.
- Drink regularly. Thirst often lags behind need.
- Eat salty snacks. Replacing salts matters when you sweat and drink a lot, as the CDC notes in its heat guidance.
If you plan to use natural water, confirm with rangers that the source is flowing, and treat it. Our guide to finding and treating water while camping explains filters and chemical treatment.
Heat Illness
Heat exhaustion and heat stroke are the most serious everyday risks of desert camping. The CDC lists heat exhaustion signs as heavy sweating, cold and clammy skin, a fast and weak pulse, nausea, muscle cramps, tiredness, dizziness, headache and fainting. Heat stroke signs include a body temperature of 103°F or higher, hot red skin that may be dry or damp, a fast strong pulse, confusion and loss of consciousness. Heat stroke is a medical emergency; call 911 and cool the person right away.
Ways to reduce risk:
- Hike early and late, resting in shade during the hottest part of the day.
- Wear light-colored, loose clothing, a wide-brimmed hat and sunglasses.
- Use sunscreen and reapply often.
- Set up shade with a canopy or tarp.
- Watch each other for early symptoms, especially children and older adults.
Our guide to hot weather camping and heat illness covers cooling methods in detail.
Flash Floods
Deserts may be dry most of the year, but when storms hit, water runs off hard ground quickly. The National Weather Service warns that flash floods can strike with little warning and that rain falling miles away can send floodwater down dry washes and canyons where no rain is falling.
Safety rules recommended by the NWS and the NPS include:
- Never camp in a dry wash, creek bed or canyon bottom.
- Check the forecast for the entire watershed, not just your campsite.
- Avoid slot canyons when storms are possible.
- Watch for signs such as rising water, muddy water, debris or a roaring sound upstream.
- Climb to higher ground immediately if flooding begins.
- Turn around, don’t drown. Never drive or walk through flooded roads.
The summer monsoon season, roughly July through September in much of the Southwest, brings the highest risk of thunderstorms and flash floods. Our guide to choosing a safe campsite explains how to read terrain for hazards.
Cold Desert Nights
Clear desert air loses heat quickly after sunset. A day in the 80s can be followed by a night in the 40s, and in winter, temperatures below freezing are common. Pack:
- A sleeping bag rated for the expected low, plus a margin
- An insulated sleeping pad, because sand and rock pull heat away
- Warm layers, including a hat and gloves
- A warm drink for evenings
Wind and Sand
Desert wind can be strong and steady. Pitching a tent can be a real challenge on open ground.
Tips for windy desert camping
- Pitch with the narrow end of the tent facing the wind.
- Use sand stakes or deadman anchors. Standard stakes often pull out of loose sand. Burying stuff sacks filled with sand or tying guylines to heavy rocks can help.
- Use every guyline the tent offers.
- Look for natural windbreaks, such as large boulders or shrubs, without crushing vegetation.
- Keep doors closed to keep sand out.
- Store gear inside or tie it down. Chairs and pads blow away quickly.
Fine dust can get into everything. Bags for electronics, cameras and food help, as does a small brush for the tent floor.
Wildlife
Desert wildlife is usually shy, but some animals can cause problems.
- Rattlesnakes are active in warm months, especially at dusk and night. Watch where you put your hands and feet, use a flashlight after dark and give snakes plenty of room.
- Scorpions hide in crevices and shoes. Shake out boots, clothing and sleeping bags before using them.
- Rodents and ravens raid food. Store food in hard-sided containers or your vehicle where allowed.
- Spiders and insects can be active at night around lights.
Our article on snake and insect safety at the campsite covers prevention and first aid.
Protecting Fragile Desert Soil
In many deserts, the ground is covered with biological soil crust, a living layer of cyanobacteria, lichens and mosses. The NPS at Canyonlands and Arches explains that this crust holds soil in place, absorbs water and adds nutrients, and that a single footstep can damage it, with recovery taking years to decades.
To protect it:
- Stay on established trails, roads and campsites.
- Walk on rock or in sandy washes (when no flood risk exists) if you must leave the trail.
- Never drive off designated routes.
Sun Protection
Desert sun is intense, and reflected light from sand and rock adds to the exposure. Use broad-spectrum sunscreen, lip balm with SPF, sunglasses and a wide-brimmed hat. Long sleeves made from lightweight fabric often feel cooler than bare skin in direct sun.
Stargazing: The Desert Reward
Dry air, high elevation and distance from cities make deserts some of the best places in the country to see the night sky. Several desert parks, including Death Valley, Big Bend and Joshua Tree, have been certified as International Dark Sky Parks by DarkSky International, the nonprofit formerly known as the International Dark-Sky Association.
To get the most from it, plan around the moon. A new moon gives the darkest sky, while a full moon washes out faint stars but lights the landscape beautifully. Let your eyes adjust for at least 20 minutes away from screens and lanterns, and use a red light to keep your night vision. A reclining camp chair or a sleeping pad laid on the ground makes long viewing sessions more comfortable. Bring warm layers, since stargazing hours are the coldest of the day.
Kids and Dogs in the Desert
Children and pets feel heat faster than many adults realize. Kids may not notice thirst or may be too busy exploring to drink, so schedule regular water breaks and watch for crankiness, flushed skin or unusual tiredness, which can be early signs of heat stress.
Dogs face extra risks. Sand, rock and pavement can become hot enough to burn paw pads in the afternoon sun. Many parks suggest a simple test: if the ground is too hot for the back of your hand for several seconds, it is too hot for paws. Dogs are also not allowed on most trails in many national parks, which limits where they can go and makes shade at camp essential. Never leave a pet in a parked vehicle, where temperatures can climb rapidly. Carry extra water for pets, and check each park’s pet rules before you arrive.
Vehicles and Remote Roads
Many desert campsites are reached by long dirt roads with no services.
- Fill your fuel tank before leaving town.
- Carry a full-size spare tire, a jack and tools.
- Bring extra water and food in the vehicle.
- Expect no cell service in many areas; consider a satellite messenger.
- Leave a trip plan with someone at home.
- Check road conditions with rangers; rain can make dirt roads impassable.
If your vehicle breaks down, the NPS and BLM advise staying with it in most cases, since a vehicle is easier for searchers to spot than a person on foot.
Campfires and Firewood
Many desert areas have little natural firewood, and gathering wood can harm fragile habitat. Fire restrictions are common, especially in summer and during dry, windy periods. Bring a camp stove for cooking, and check current fire rules before planning a campfire.
Free Camping in the Desert
Much of the desert Southwest is managed by the BLM, where dispersed camping is often allowed. Popular areas include parts of Arizona, Nevada, Utah and southern California. Stay limits, fire rules and road conditions vary by field office. Our guide to dispersed camping rules explains the basics.
