Hiking & Backpacking

While there are no formal trails within Aniakchak National Monument & Preserve, hikers and backpackers will find excellent hiking conditions atop the ash and cinder fields of the caldera floor.

Because the Aniakchak landscape also features swift, cold rivers and seemingly impenetrable patches of dense vegetation, the path of least resistance will often be an animal trail. Be sure to make noise as you walk in these conditions to warn wildlife of your approach.

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.
