The Aniakchak region is prime habitat for land mammals, waterfowl, marine mammals, fish and shellfish, and extensive wild runs of five salmon species of Pacific Salmon. Aniakchak includes nursery areas for sockeye salmon runs that are part of the Bristol Bay and Kodiak/Chignik sockeye fisheries. Brown bear, caribou, moose, wolf, wolverine, waterfowl, sea otter, harbor seal, sea lion, and numerous smaller species inhabit the area. Most of the land species range freely throughout the area. Brown bear, caribou, fox, ground squirrel, and eagle are known to inhabit or visit the caldera.

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.
