Checking park alerts…

Alerts: National Park Service, checked hourly. Forecast: National Weather Service, for Grand Canyon Visitor Center (South Rim). Always confirm on the official park site before you set out.

Stay safe

  • Wildlife: Keep at least 25 yards (23 m) from all wild animals, and 100 yards (91 m) from bears and wolves where they live. Never feed wildlife. Use pullouts to watch animals from the road.
  • Heat and water: Carry and drink at least one gallon (4 liters) of water per person per day, more when hiking in heat. Hike early or late in summer, eat salty snacks, and turn back when half your water is gone.
  • Cell service: Coverage is patchy in most parks. Download offline maps and the park’s info before you lose signal.

What to pack

Start with the park service’s ten essentials:

  • Navigation: a paper map or offline map, plus a charged phone and battery pack
  • Sun protection: sunglasses, sunscreen and a hat
  • Layers: a warm layer and a rain shell, even in summer
  • Headlamp or flashlight
  • First aid kit
  • Fire starter (matches or a lighter) for emergencies
  • Repair kit and tools (a small knife, tape)
  • Extra food
  • Extra water and a way to treat it
  • Emergency shelter: a space blanket or tarp

For Grand Canyon also bring:

  • At least one gallon of water per person per day, plus electrolyte drinks or salty snacks
  • Lightweight long sleeves and a wide-brim hat
  • A cooler and shade for the car
  • A red light and a blanket for stargazing
  • Binoculars for wildlife watching from a safe distance
  • Camping: tent, sleeping bag rated for night temperatures, camp stove and fuel bought locally

What to leave at home

  • A drone: launching, landing or flying drones is banned in almost every national park site.
  • Firewood from home: it can carry tree-killing pests. Buy it where you burn it, ideally within 10 miles.
  • Pets: check the park’s pet rules before you bring a dog. Where pets are allowed they must be on a leash no longer than 6 feet.
  • Anything you plan to take home from the park: rocks, plants, antlers, artifacts and fossils must stay where you find them.
  • Food that wildlife can reach: store it as the park directs, in your car or a locker, never in a tent in bear country.

Weather

Since Grand Canyon has elevations that range from 2,500 feet at the bottom to 8,400 feet on the North Rim, weather can vary significantly depending on the season and the specific location within the park. Winters tend to be cold and snowy, and summers have periods of excessive heat. High temperatures inside the canyon tend to be 20 to 30 degrees warmer then on the canyon's rims. Weather conditions can change rapidly, so it's wise to check forecasts before visiting.
