Mauna Iki Trail

Mauna Iki Trail traverses a remarkable section of the Kau Desert within Hawaii Volcanoes National Park, passing through a landscape shaped by successive volcanic eruptions and preserved in striking detail by layers of ash and hardened lava. The trail loops through an otherworldly terrain of pahoehoe lava fields, cinder cones, and open ash flats that receive minimal rainfall due to their position in the rain shadow of Kilauea. One of the most historically significant features along this route is a preserved set of human footprints embedded in volcanic ash, left by warriors and their families during a devastating eruption of Kilauea in 1790. The footprints, among the oldest preserved human traces in Hawaii, offer a haunting connection to an ancient tragedy. The trail also crosses Mauna Iki itself, a low shield vent, and passes through sections of older pahoehoe lava that display beautiful rope-like flow patterns. Vegetation is sparse but includes native ohelo berry bushes and occasional silversword relatives adapted to the harsh conditions. Hikers must carry all water, as none is available along the route. The exposed terrain and dark lava can create intense heat on sunny days, so early morning starts are strongly recommended. Navigation markers help guide the way across sections where the trail blends with the surrounding lava. This trail rewards those seeking geological history and solitude.
