This trail is closed. It is not in the National Park. 

Route Description

This trail is completely closed, and will be closed for some time to come. Do not hike here. 

Aerial view looking southwestward shows the active vent within Pu`u `O`o crater. Lava often poured from the vent across the sloping crater floor and drained into the pit at the opposite (downrift) end of the crater. Several times in 1997, lava filled the crater and spilled over the east rim, draping the east flank of the cone with bright silver pahoehoe (lower left). Photograph by J. Kauahikaua on October 2, 1997


Essential Gear

Trail closure

In early January 2013, a very mean looking sign complete with law quotes warned of imprisonment and heft fines for hiking this trail.
