Permits are not required for public access to or overnight stays within Aniakchak National Monument and Preserve. Please be aware, however, that Aniakchak contains numerous parcels of privately-owned land. Access to private lands is prohibited without prior consent of the landowner.
Visitors should leave itinerary information with a friend or family member. Be sure to include float plan details (if applicable), the name of the trip leader, the air taxi operator's name and contact information, type and color of equipment/clothing used, and anticipated date of return. The NPS will not initiate a search for an individual or group unless they are reported overdue. Aniakchak visitors are also encouraged to submit the same information in a "Backcountry Planner," available free-of-charge at the King Salmon Visitor Center.

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.
