Operating Hours & Seasons
Aniakchak National Monument and Preserve is a truly primitive landscape with no federally-maintained public facilities. The National Park Service imposes no operating hours or seasonal restrictions. Access to and movement within Aniakchak, however, may be limited or restricted at any time depending upon prevailing weather conditions and/or volcanic activity.
Please also be aware that in-holdings of private property exist within the monument and preserve. At no time is it permissible to enter private lands without prior consent from the landowner. Please respect the rights of property owners and avoid illegal trespassing.
