Kaumana Caves

The Kaumana Caves is a large, over 2 mile lava tube created by a Mauna Loa eruption from 1881. This hidden gem is free to visit, and just a few miles away from Rainbow Falls in Hilo.

You can park alongside the road, and explore the inside of the lava tube. There’s hanging vines at the entrance, and the cave’s walls are surrounded by interesting lava flow patterns.

Make sure to bring a flashlight and wear hiking shoes, as the inside is completely dark and the trail is made of lava rock. 

Rainbow Falls
