I've done this dive several times as a twilight/night dive, and it's a very mellow place with a great reef, and typical Kona drop-off to the abyss. There are some large fish that swim by, turtles, eels, lots of other critters. Sheltered bay/entry. Bit of a hike over the pahoehoe lava (ropey basalt), but it's worth it. Just watch out for the black sea urchins in the shallows (ouch).
