Big Island Travel Guide
The Kanohina Lava Tube system is about 1,000 years old and was used by the ancient Hawaiians for water collection and for shelter. More than 40 miles of these braided lava tubes have been mapped so far in the Kau District of the Big Island, near South Point. About 45 miles south of Kailua-Kona, these lava tubes are a great experience for cavers of all age levels and abilities.
