Aniakchak is one of the most wild and least visited places in the National Park System because of its remote location and challenging weather conditions. This landscape is a vibrant reminder of Alaska's location in the volcanically active Ring of Fire, and it contains a six mile wide, 2,500 foot deep caldera formed during a massive volcanic eruption 3,500 years ago. Wet and cool conditions usually predominate in spring, summer, and fall, and strong winds can delay the departure and arrival of boats and floatplanes.
