Located on Highway 132 in East Hawaii and situated in the Nanawale Forest Reserve, this park is a graphic depiction of the long-term effects of lava. Hundreds of years ago a fast-moving flow of hot lava encountered a patch of wet `O`hia trees and forever “molded” the structures, leaving behind vertical, hollow, lava tubes where each tree once stood. Open daily from dawn to dusk, free, 30-60 minute hikes traverse the park. Wear sturdy shoes and walk slowly and carefully as the terrain is very uneven. There are restrooms and picnic tables.

Getting Here:
South on Highway 130 out of Pahoa, turn east onto Highway 132. The park is 2.5 miles down this highway on the left.
