Of all of the Maui sights listed here (I have dove and snorkeled every one) this is my favorite for snorkeling and right up there for diving. On the North side - just outside the reserve area - is a world class surf spot in the Winter and the viz ain't so hot. Also, if a heavy rain falls in the wash above, the water muddies up for awhile. But the rest of the time this place rocks! Driving up Hwy 30 go about a half mile past MM32. That's where you park where you can and follow the old road around the locked gate with the keep out sign (it's really ok!) and about a 1/8 mile walk under a beautiful canopy of trees, you'll find the old boat ramp. Enter here. On your left (Southside) is the more colorful side. Great snorkeling for amateurs and old salts alike. Lot's of overhangs and swim-throughs. If you are diving, keep going around the points and you might reach 50 feet of depth. The other side is cool too. Snorkel on top the reef or scuba along the edge. More turtles. I have seen a few big critters on this side as well. Dolphins, Mantas, spotted eagles, and white tipped reef sharks. All few and far between but the do come in there sometimes. Both sides are great for night scuba or snorkeling.
