A must see n do !
10.5 miles north of the Kona airport, past mile marker 83. Use the Vista overlook to safely turn around and access this Hard to Find, not well marked road.
Slowly drive down this maintained dirt road to the fork. Stay right and park at the end.
Walk north down the beach approx 400 yards, to find this Fine lava tube filled with fresh water !
Bring shoes, a bicycle helmet, a kick-board and a headlamp for an interesting swim in a lava tube !
