About this site
3Room Cave lies along the Kona coast of the Big Island of Hawaii, an area of the state known for its lava rock shoreline dropping into clear, deep offshore water. Sites along this coast are typically reached by boat out of harbors like Honokohau, with the volcanic terrain shaping much of the underwater topography.
