Lava Tree State Monument is a state park in Puna near Pahoa, where a lava flow swept through a forest and left behind lava molds of the tree trunks. USGS places the monument on the lower east rift zone of Kīlauea, with lava trees and molds left behind by an earlier eruption. Where the lava drained away, pillars of lava were left standing where the trees had been. A short loop trail winds through the forest of lava trees. There are picnic tables, a restroom, trash cans and a walking path, but no drinking water, so bring your own. The park is open daily during daylight hours, and there is no entrance fee. State Parks lists a hazardous cliff as a hazard here, so keep to the path and keep children close. Pets, alcohol, smoking, camping and motorized vehicles are not allowed. In its hurricane recovery notice of mid October, State Parks reports that Hawaiʻi island parks have reopened, with some exceptions; check its Park Notices site before you go.
