Aniakchak National Monument and Preserve is located about 450 miles southwest of Anchorage, Alaska, on the roadless Alaska Peninsula. It is one of the most wild and least-visited places in the National Park System due to its remote location. The monument sits atop a six-mile-wide caldera formed during a massive volcanic eruption about 3,500 years ago and is a reminder of Alaska’s location in the volcanically active “Ring of Fire”. The ten-square-mile preserve includes the caldera, the wild Aniakchak River, the Bristol Bay coastal habitat, and rugged bays and inlets of the Pacific Ocean coastline.
