Aniakchak protects a caldera about 6 miles wide and 2,500 feet deep, left by a huge eruption some 3,500 years ago. Inside you find lava flows, cinder cones and Surprise Lake, the source of the Aniakchak River. There are no roads, trails or facilities, and bad weather often delays flights for days, so pack extra food and build slack into your plans.
