About Lava Tree State Monument

 

Lava Tree State Monument is located on the Big Island of Hawaii near the town of Pāhoa. The site showcases unusual lava molds of tree trunks created during a volcanic eruption around 1790 when lava flowed through a tree-dense area. As the lava engulfed the trees, their outer layers cooled and solidified while the tree's interior burned away, leaving hollow molds that stand as natural lava casts resembling petrified trees. The monument covers a compact area with a paved trail circuit approximately half a mile long, allowing visitors to walk around the lava flow and closely inspect these geological formations. The surrounding environment consists of a native ohia and hala forest, supporting local bird species and native plants. This area offers an educational glimpse into volcanic processes and prehistoric lava flows. Beyond geological curiosity, the park provides an easy, family-friendly hike, ideal for learners and photographers interested in volcanic landscapes. Facilities include a picnic area and educational signage. The monument's proximity to active volcanic zones gives visitors insight into Hawaii's volcanic activity, though lava flows at this site are historic and no current volcanic hazards exist. Lava Tree State Monument offers a quiet, accessible outdoor experience connecting visitors to Hawaii’s dynamic geological past.
