This is a great spot for SCUBA beginners. The
easiest entry point I can imagine - sandy beach, no currents, additionally
good facilities: showers, restrooms.
The reef is typical for Hawaii, you can find a lot of fishes, including my favorite big-eyes fish, a lot of turtles. On the outer reef (about 20min. off the shore) the bottom deepen a little bit to about 11m (35feet) and you can even find few small trenches there. To sum it up it's a good place for the first dive especially if you haven't been diving recently.
