Kula Kai Caverns
Kula Kai Caverns information
Top-notch underground tours are led by local experts who emphasize respectful stewardship of these 'living museums.' The geologically astounding caves belong to the world's longest lava tube system, reaching back into the bowels of Mauna Loa volcano. On the basic 30-minute tour, you'll enter a short, lighted cave section, where guides present Hawaiʻi's cultural and ecological history. Reservations are required.
There's also a longer 'crawling' tour ($60) and a two-hour extended twilight tour ($95). Group sizes are kept small, usually with a two- or four-person minimum. Children (minimum age six or eight years) are allowed on most tours.
