Forest of lava trees resulting from eruption of a 1-km-line of vents east of Pu‘u Kahaualea. The bulbous top of each lava tree marks the high stand of the lava flow as it spread through the trees. As the fissure eruption waned, the flow continued to spread laterally; its surface subsided, leaving pillars of lava that had chilled against tree trunks.
A 0.7-mile (1.1 km) foot path forms a loop through the park. Like all Hawaii state parks, there is no charge for parking and entry. Facilities include restrooms, picnic tables, and 3 covered structures to provide refuge from the rain or sun. It is open daily during daylight hours only, since there are no lights on the path. No camping, and no mountain bikes are allowed in the park. There are no water fountains at the park; bring your own. Although there is a paved path, tree roots have lifted and separated parts of the path so toddlers and the elderly may need assistance.
