Aniakchak National Monument and Preserve encompasses 586,000 acres of pristine Alaska wilderness. While rafting the Aniakchak River, hiking the caldera floor, and sport fishing are among the most common activities pursued, the possibilities for adventure are limitless for those visitors determined and prepared enough to experience Aniakchak on its own terms.
