Awesome spot. Saw plenty fish and a whitetip off the 'cathedral'. Recommend to go all the way past the houses on your right and you have good parking spaces and a trashcan. Enter the water just after the parking on the right side, just before the lava 'wall' begins. A lone tree marks it for future access. Swim directly out and slightly angling to the north, into the old lava tube that starts there, about 20ft down. Follow this out and to the right and into the next lava tube that ends in the 'Cathedral', an awesome swim into where the light enters from holes from above. Saw a turtle and a whitetip resting in there! Unfortunately no facilities, but there's a small shop just up the road, and easy access to rental gear and tanks just up the coast!
