Probably my favorite site on the Big Island. Don't let the road scare you. We made it with our rental. A jeep or SUV will make it easily, but any compact will do okay. Just go slowly. Please respect the residents in this area. You are basically diving in their backyard. Keep the noise down and clean up after yourself. Use the primitive boat launch next to the stone wall as your entry/exit. It's easy to find coming back. This is a large site and will take several dives to even begin to see the whole thing. A good place for a two tank day. Good channels to explore and some neat lava tubes and chimneys. Keep an eye out for pelagics.
