Death Valley is safe for prepared visitors and dangerous for unprepared ones. The risks are well known and easy to manage if you take them seriously. This guide covers the essentials.
Water
Carry far more than you think you need. A common rule is at least a gallon per person per day in the cool season and more in the heat, plus extra in the vehicle in case of delay. Drink regularly rather than waiting until you are thirsty, and eat salty snacks to replace what you sweat. Do not rely on finding water on the trail. Refill at the visitor center and at the villages.
Heat
In summer, valley-floor temperatures can pass 115 degrees, and ground temperatures are higher. Heat illness comes on quickly, with headache, dizziness, nausea and confusion. If someone shows symptoms, get them into shade or air conditioning, give water and seek help. Avoid hiking in low areas after mid-morning in the warm months. Wear a wide-brimmed hat, light long sleeves, sunglasses and sunscreen. Never leave children or pets in a parked vehicle.
Fuel
Fill the tank before you enter the park. Fuel is available at Furnace Creek, Stovepipe Wells and Panamint Springs, but prices are high and supplies can run out. Distances are long, and the air conditioning uses extra fuel. Plan your route with a margin.
Your vehicle
Check your tires, spare and fluids before the trip. In summer, watch the temperature gauge, and if the engine overheats, pull over safely and let it cool. Do not run the engine hard on steep roads such as the climb to Dante's View, and use a lower gear going downhill. A standard car is fine for the paved roads. For gravel roads such as the Racetrack, you need a high-clearance vehicle and a full-size spare.
Signal and navigation
Mobile signal is poor or absent in most of the park. Download offline maps and any audio tours before you arrive, carry a paper map from the visitor center and tell someone your plan. A power bank is useful.
Flash floods
Desert storms can cause sudden floods, even when the sky overhead is clear. Avoid canyons and washes when rain is forecast, never drive through flooded roads and heed closure signs. Floods can damage roads and trails, so check conditions with the park service before heading out.
Wildlife
Rattlesnakes, scorpions and other animals live in the desert. Watch where you put your hands and feet, and do not approach wildlife. Drive carefully at dusk and dawn, when animals are active on roads.
Hiking safety
Start early, choose trails that suit your fitness, carry water and tell someone where you are going. Turn back if you feel unwell. Stay on trails and do not enter abandoned mines, which are dangerous.
What to pack
Water, snacks, hat, sunglasses, sunscreen, layers, sturdy shoes, a first-aid kit, a flashlight, a power bank, a paper map and a camera. In winter add a warm jacket and gloves for dawn and dusk. For rough roads, add a spare tire, a jack, a tire gauge and a repair kit.
If you do not want to manage all this
A guided tour from Las Vegas takes care of the driving, water and heat planning, which is a big advantage in summer. A sunset tour also lets you enjoy the cooler evening without driving back in the dark.
Respect the park
Pack out what you bring in, stay on paths, do not feed animals and leave rocks and artifacts where you find them. Following these rules keeps the park beautiful and safe for everyone.
A simple pre-trip checklist
Check the park service website for road and trail conditions, closures and weather alerts. Fill the tank and check the tires. Pack water, food and a first-aid kit. Download offline maps and tours. Tell someone your route and expected return time. Start early, and plan a midday break. Know the signs of heat illness. Respect closures and warnings. With these steps in place, the park becomes a place of wonder rather than worry, and you can spend your energy on the views instead of the logistics.
Traveling with children and older adults
Heat affects the very young and the elderly more quickly, so keep outings short and shaded, offer water often and watch for flushed skin, tiredness or irritability. Plan indoor breaks at the visitor center, a pool or an air-conditioned room. Choose viewpoints that are close to the road rather than long hikes, and bring snacks and entertainment for the drives. A relaxed, flexible plan lets everyone enjoy the day and keeps the trip safe.
