Take a (Short) Hike
Denali is massive and mostly devoid of man-made trails, and only experienced backpackers should attempt to explore the wilderness on foot. That said, there are a few maintained and easily accessible trails for folks who want to move their legs and get an up-close feel for the park without the danger of getting lost or crossing a river.
Free courtesy shuttles run from central park sites such as the Denali Visitor’s Center and the Wilderness Access Center, but you can also ride it to maintained hiking trails such as the Savage River Trail, 15 miles down the park road.
There are many other one-day activities to do while visiting Denali National Park that offer adventure and unique experiences. You can take a flightseeing tour and land on a glacier, raft the Nenana River, or visit a sled dog kennel to watch a demonstration of this mode of transport.
