Alaska
🔴 hikes
Free entry
Given its remote location and challenging weather conditions, Aniakchak is one of the most wild and least visited places in the National Park System. This landscape is a vibrant reminder of Alaska's location in the volcanically active "Ring of Fire," as it is home to an impressive six mile (10 km) wide, 2,500 ft (762 m) deep caldera formed during a massive volcanic eruption 3,500 years ago.
Activities
No entrance fee.
Hours
Aniakchak National Monument is a truly primitive environment with no federally-maintained public facilities. The NPS imposes no operating hours or seasonal restrictions. Access to and movement within Aniachak, however, may be limited or restricted at any time depending upon prevailing weather conditions.
