Hiking along the Road

Keanakākoʻi means "cave of the adzes" because kahuna kākoʻi (carving experts) sought the hard basalt rock in the crater to create tools. Lava covered the ancient adze quarry in 1877, burying it forever. This hike travels past Keanakākoʻi Crater and ends at an overlook of the southeastern side of erupting Halema'uma'u Crater. This is the closest one can currently get to Halema'uma'u. This hike actually follows a portion of Crater Rim Drive that was closed in 2008 when the current eruption began. Sulfur dioxide from the eruption can cause respiratory distress to those with heart and lung conditions, pregnant women, and young children. The trade winds will normally carry gas away from this area, but stay aware for changing winds. This hike is open from 7am - 7pm.

Hike: From the Devastation Trail parking lot, hike back toward Crater Rim Drive. At the intersection of Crater Rim Drive and Chain of Craters Road, head west past a road barrier onto the closed portion of Crater Rim Drive. Walk the closed road for just over a mile through koa and ʻōhiʻa forest and find Keanakākoʻi Crater to your south. The hike continues a bit to a marked overlook set off by fences. This is the end of the hike - do not leave the marked area. Take in the big views of Halema'uma'u and looming Mauna Loa. Return the way you came.
