A visit to Denali includes a stop at the visitor centers, a drive on the park road or taking a bus deep into the wilderness. A majority of the visitors choose to come to the park between mid May and mid September when these services are offered, however the park is open all year for those who wish to travel by ski or dog sled.  The entrance area is where you’ll find most of the amenities of the park. There is the Denali Visitor Center, Wilderness Access Center, Murie Science and Learning Center, Riley Creek Campground, Denali Park Post Office, Riley Creek Mercantile, Railroad Depot and trailheads.
