During summer, personal cars cannot drive past the Savage River at Mile 15. The remaining 77 miles of the 92-mile Denali Park Road are unpaved and open only to official park buses.
This restricted access protects the 6-million-acre wilderness and its wildlife. Riding a bus deep into the park gives you the best chance to spot grizzly bears, wolves, moose, and caribou across the open alpine tundra.
2026 update: the road is closed at Mile 43 while the Pretty Rocks bridge is finished. Transit and tour buses go no farther than East Fork, and Eielson Visitor Center and Wonder Lake are out of reach this season. Full access is expected to return in 2027.
