Denali in August: what the park service says
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. Annual and lifetime pass holders can get the $15 entrance fee refunded at the bus depot or Riley Creek Mercantile.
