The snorkeling here was great. Its actually a lot better than it is at Hanauma Bay, since the water is much clearer. Its deeper than at Hanauma Bay, so you cant get as close to the fish, but overall, its a much better experience.
Parking in the small lot off the main road is impossible. Not only is the lot full, but when you get there, there will probably be a handful of people sitting in their cars just waiting for a space to free up. Instead of joining them, go north and when you get to town, park there and walk back. Its not that far and you will be on the beach before the people waiting even park their car.
