Know before you go: Denali

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.
• Bears: Grizzly and black bears live here. Carry bear spray where you can reach it and know how to use it, hike in groups, make noise on the trail and store all food and scented items as the park directs.
• 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 Denali also bring:

• Bear spray in a holster you can reach (buy or rent it near the park; it cannot go in checked or carry-on bags on most flights)
• A warm hat and gloves: mornings can be freezing even in summer
• 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: of the 5 hikes the park service lists here, 0 allow pets. 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

Summer is typically cool and wet, with highs typically in the upper 50s to low 60s, and lows in the 40s. On occasion, summer highs reach the low 80s, though this is rare. Snow can fall any month of the year, so be prepared for chilly weather even in summer. Fall colors emerge on the alpine tundra in August and in the low valleys in early September. Winter generally starts in mid-September, with temps often getting down to -40 by January. Spring is a short season in April / May, with highs above freezing.
