Ahjumawi is a place of exceptional, even primeval, beauty. Brilliant aqua bays and tree studded islets only a few yards long dot the shoreline of Ja-She Creek, Crystal Springs, and Horr Pond. Over two thirds of the area is covered by recent (three to five thousand years) lava flows including vast areas of jagged black basalt.
The park is a wilderness area and most of it is extremely rugged lava rock. Visitors should prepare adequately for their visit. While there are over twenty miles of park trails by which to explore this beautiful geographical wonder, please be advised that travel off the trails requires proper preparation and equipment. Be sure someone knows where you are going and when you expect to return.
The park is reachable only by a 2.5-mile paddle in your own shallow-draft boat
