Must do this site. Very easy entry and exit (two steps down into the water from the lava plateau), great life at the wall, resident spinner dolphins. Usually you can either park on the side of the road or pay $3 and park at the lot across the road if its too crowded. From the entry point navigate to heading 330 until you see 'Aloha' on the bottom, then go 270 or follow the wall out. Facilities are available at this site.
