The Alaska Peninsula refuge skirts the Pacific side of the Alaska Peninsula. The refuge's varied landscape includes active volcanoes, lakes, rivers, tundra and rugged coastline.

The peninsula refuge includes the rugged Aleutian Range of volcanoes that are part of the Pacific Ocean's "Ring of Fire" volcano chain.

Large mammals found on the refuge include moose, caribou, wolves, brown bears and wolverines. Brown bears congregate around streams of spawning salmon.

Thriving populations of sea lions, seals, sea otters and migratory whales inhabit the shores and offshore waters.

Shorebirds and migratory waterfowl are found throughout the refuge.

Spring, summer and fall are the best seasons to visit the refuge.
