Running beyond Mauna Ulu requires a permit, available at Klauea Visitor Center.
Experience a lava landscape from the 1969-1974 Mauna Ulu flow. Run by lava tree molds and climb 210 feet (64m) to the top of a forested cinder cone, Puu Huluhulu (hairy hill). View Mauna Ulu's steaming shield, which is similar to the now active Puu cone in the distance. On a clear day, you can see Mauna Loa, Mauna Kea, and the Pacific Ocean.
