Few people go to remote Aniakchak National Monument and Preserve. Its acres are among the least visited in the National Park System. Notoriously bad weather combines with costly and unpredictable access to discourage most potential visitors.

Although the unit is hard to get to, it offers spectacular scenic vistas and examples of geologic and hydrologic activity.

The Aniakchak (Big) River drops more than 1,000 feet in elevation within the first 15 miles leaving the caldera. The final 12 miles of the 27 mile river is a smooth, winding float along the open tundra. Watch for bears, moose, and other wildlife as you float.
