Why Desert Preparation Is a Different Kind of Challenge

American deserts are some of the most spectacular landscapes on the planet — think Joshua trees silhouetted at dusk, towering saguaro cacti in the Sonoran, or the alien salt flats of the Great Basin. But these environments are also genuinely hazardous, and they don't forgive poor planning the way a beach vacation might. Temperatures in the Mojave can exceed 120°F (49°C) in summer, and exposed terrain means that shade, water, and help may all be hours away.

This checklist is designed to help everyday travelers — not just hardcore backpackers — prepare for a visit to any US desert environment. Whether you're day-hiking in Saguaro National Park, driving through Death Valley, or exploring Red Rock Canyon, these steps apply. Use it alongside our pre-departure checklist to make sure the basics are covered before you even leave home.

Heat-Related Illness Is a Medical Emergency

Heat stroke — characterized by a high body temperature, confusion, and hot dry skin — can develop rapidly in desert conditions and is life-threatening. If someone shows signs of heat stroke, move them to shade, cool them down with any available water, and call 911 or emergency services immediately. Do not wait to see if symptoms improve on their own.

What You'll Need: Essential Tools and Gear

Before running through the checklist itself, gather your equipment. Desert travel demands specific gear that you may not already own. Below are the key items to have on hand — many can be sourced from outdoor recreation or general retail stores.

Required

Insulated water bottles or hydration reservoir

Keeps water cooler longer and makes it easier to maintain consistent drinking during strenuous activity.

Required

Offline navigation app with downloaded maps

Provides turn-by-turn trail and road navigation when cell coverage is unavailable.

Optional

Satellite communicator (e.g., personal locator beacon)

Allows you to call for emergency help or send location updates from areas with no cell signal.

Required

Wide-brimmed sun hat and UV sunglasses

Reduces direct sun exposure on your face, neck, and eyes during exposed desert hiking.

Required

Electrolyte packets or sports drink mix

Replenishes sodium and minerals lost through heavy sweating in high-heat environments.

Required

Sturdy, broken-in hiking footwear

Protects feet from rocky, uneven terrain and reduces blister risk on long desert walks.

Required

Basic first aid kit

Covers blisters, cuts, minor sprains, and insect stings — common minor injuries in desert terrain.

Optional

Emergency space blanket

Provides insulation if temperatures drop sharply overnight and can double as a sun shade in an emergency.

The Desert Readiness Checklist

Work through each group below before your trip. Items marked must are non-negotiable for your safety. Should items are strongly recommended for most visitors, and nice-to-have items add comfort or contingency. Conditions vary by season, elevation, and specific desert — always check current conditions with the relevant National Park Service or land management agency website before you go.

Timing and Itinerary Planning

Check the forecast high temperature for each day of your visit and plan to be off exposed trails by 10 a.m. if temperatures will exceed 95°F. Must
Research sunrise and sunset times for your destination so you can schedule early-morning hikes with accurate light windows. Must
Share a detailed written itinerary — including trailheads, planned return times, and campsite locations — with someone not on the trip. Must
Check for current trail closures, fire restrictions, and road conditions via the National Park Service or BLM website before departure. Must
Identify the nearest emergency services, hospital, and ranger station to each location you plan to visit. Should

Hydration and Nutrition

Pack at least one liter of water per person for every hour of hiking planned, then add 20% as a buffer. Must
Bring electrolyte packets or salty snacks to replace sodium and minerals lost through sweat — plain water alone is insufficient during heavy exertion in extreme heat. Must
Store water bottles in an insulated bag or cooler; water in uninsulated plastic bottles left in direct sun can reach temperatures that discourage adequate drinking. Should
Identify water sources along your route in advance — do not assume any natural source will be accessible or safe without treatment. Must
Pack calorie-dense, heat-stable snacks such as nuts, dried fruit, and jerky rather than chocolate bars or items that melt. Should

Sun and Heat Protection

Apply broad-spectrum sunscreen rated SPF 30 or higher before going outdoors, and carry it with you to reapply every two hours. Must
Wear a wide-brimmed hat, UV-protective sunglasses, and lightweight long-sleeved clothing to reduce sun exposure on skin. Must
Learn to recognize the early signs of heat exhaustion — heavy sweating, weakness, cool or pale skin, nausea — so you can respond before symptoms escalate. Must
Pack a small personal emergency blanket; it can reflect radiant heat in an emergency shelter situation as well as retain warmth if desert temperatures drop sharply at night. Should
Wear gaiters or ankle-covering footwear on sandy trails to protect against thorns, spines, and ground-dwelling insects. Nice to have

Navigation and Communication

Download offline maps of your destination before leaving cell coverage — apps like Gaia GPS or Avenza allow you to navigate without a signal. Must
Bring a physical paper map and a compass as a backup to electronic navigation tools. Should
Consider renting or purchasing a satellite communicator device for remote areas where cell coverage is absent. Should
Charge all devices fully before departure and carry a portable battery pack to extend phone life. Should
Register with the ranger station or trailhead logbook when one is available, so rangers know to look for you if you don't return on schedule. Nice to have

Don't Rely on Assumed Cell Coverage

Large sections of the Mojave, Great Basin, and Sonoran deserts have no cell service at all. GPS apps may still function offline, but you cannot count on calling for help with a standard smartphone. Always carry a backup communication plan — and tell someone your itinerary before you lose signal.

Summer Visits Carry the Highest Risk

Peak summer months (June through August) bring the most extreme heat to US desert regions. Some areas, including Death Valley, actively advise visitors to avoid hiking during daylight hours in summer. Consider visiting in spring (March–May) or fall (September–October) for a far more manageable experience.

Getting Your Vehicle Ready for Desert Conditions

Your car is your lifeline in remote desert terrain. Breakdowns that would be a minor inconvenience near a city can become genuine emergencies when the nearest town is 50 miles away and the temperature is triple digits. Check your coolant, tire pressure, and battery before departure — heat accelerates wear on all three. Our seasonal vehicle preparation checklist walks through exactly what to inspect before driving in extreme summer heat.

Carry extra water in your car — not just for drinking during hikes, but in case your vehicle overheats. A gallon per person per day is the general guidance for consumption, but having additional water in the trunk provides a genuine safety buffer if plans change.

Always verify current conditions, closures, and safety advisories with official sources such as the National Park Service or relevant land management agencies before visiting any desert area. In a medical emergency, call 911 or contact park emergency services immediately.
