Common questions

Denali month by month: notes from the park service

• January: January keeps Denali in its extreme cold, which typically runs from late October or early November through March. Winter is the predominant season this far north, the park points out, and it is a time for skiing, snowshoeing and winter biking, the last only on the Roadside Bike Trail and the park road.
• February: In February you can still visit Denali's sled dogs: in winter the kennels open on Saturdays and Sundays from 1 to 4 p.m., hosted by a ranger, though the teams are sometimes out on the trail. The park has used working dog teams since 1922.
• March: March is the last month of Denali's long cold stretch, though snow cover can range from excellent to nonexistent and temperatures from 40°F to -40°F, the park notes. There are no winter gear rentals near the park, so bring your own skis or rent them in Fairbanks or Anchorage.
• April: April at Denali is still the park's winter set-up. The park service says only the Winter Visitor Center and Riley Creek Campground are open in winter.
• May: May is when Denali's summer opens. In 2026 the Natural History Tour began on May 13 and the Tundra Wilderness Tour on May 20, and because of the Pretty Rocks Landslide no bus went beyond mile 43 of the park road.
• June: By June both of Denali's narrated bus tours are running: in 2026 the Natural History Tour started May 13 and the Tundra Wilderness Tour May 20, both about five hours round trip. With the Pretty Rocks Landslide still closing the road beyond mile 43, that is the farthest any bus goes.
• July: July is the heart of Denali's bus season. In 2026 the park's narrated tours ran from mid-May to mid-September, and because of the Pretty Rocks Landslide no bus goes farther than mile 43 of the park road, near the East Fork River.
• August: August is still full bus season at Denali: in 2026 both narrated tours ran into mid-September, and no bus went past mile 43 of the park road because of the Pretty Rocks Landslide. Pick the green transit buses if you want to get off to hike or picnic; the tan tour buses come with a naturalist driver but are not for hopping on and off.
• September: September is the end of Denali's bus season. In 2026 the Natural History Tour ran until September 15 and the Tundra Wilderness Tour until September 17, and because of the Pretty Rocks Landslide no bus went past mile 43 of the park road.
• October: October at Denali is the turn to winter: the park service says that in winter only the Winter Visitor Center and Riley Creek Campground are open, and once heavy snow falls the park road closes to cars at Park Headquarters, mile 3, for the season. Riley Creek, near the entrance, takes RVs and tents year-round and charges fees only in summer.
• November: November is Denali in winter mode. The park service says that in winter only the Winter Visitor Center and Riley Creek Campground are open; Riley Creek, a quarter mile in, takes RVs and tents all year and charges fees only in summer.
• December: December at Denali is deep winter, with very short days and temperatures that can sink to -40°F or below, the park says. The Murie Science and Learning Center at mile 1.3 serves as the winter visitor center, where you can borrow snowshoes and ice grippers and pay the entrance fee by card only.
