Outdoor Activities

With no trails, campgrounds, or other facilities—indeed, almost no sign of human impact whatsoever—visitors to Aniakchak must create their own adventure. In this dynamic, ever-changing landscape, whatever activity visitors choose to do has likely never been done the same way, nor under the same conditions. Expect the unexpected, and do not attempt to plan and carry out a trip based solely on the information contained in this website. Solo travel is not recommended.

Did You Know?

Ash from the May 1931 eruption of Aniakchak fell at a rate of a pound per hour at the Chignik villages, 65 miles to the south. The blast was heard 200 miles away and the ash sprinkled the ground nearly 700 miles from the source. The eruption left a caldera 250 deep and one-half mile wide.
