Class IV Aniakchak River, AK

Surprise Lake to Aniakchak Bay

Lying entirely within Aniakchak National Monument and Preserve, you can float the river from inside the caldera of a volcano to the ocean past spectacular wildlife and geology.

The river moves swiftly through a narrow gorge, and large rocks demand precise maneuvering. Only the most experienced rafters contemplate this float trip that takes three to four days to complete.
