About the Park
Given its remote location and challenging weather conditions, Aniakchak is one of the most wild and least visited places in the National Park System. This landscape is a vibrant reminder of Alaska's location in the volcanically active "Ring of Fire," as it is home to an impressive six mile (10 km) wide, 2,500 ft (762 m) deep caldera formed during a massive volcanic eruption 3,500 years ago.

Raft the Aniakchak River
Rafting Aniakchak River is both a challenging and rewarding experience.
Visitor Centers
King Salmon Visitor Center
Located next door to the King Salmon Airport, the King Salmon Visitor Center provides information on the many federal public lands of Southwest Alaska, particularly those in the Bristol Bay area. A large collection of films is available for viewing and an Alaska Geographic bookstore sells maps, charts, videos, posters, clothing, souvenirs, and more.

How to Get Here
Located on the Alaska Peninsula, 450 miles southwest of Anchorage, Aniakchak National Monument and Preserve is inaccessible by road. Notoriously bad weather makes access to Aniakchak unpredictable. Drop-offs and/or pick-ups may be significantly delayed.
