Great for turtles when the water is calm! I thought this would be a horrible spot based on how crowded it was, but it turned out to be some of the best snorkeling I experienced on our trip. The beaches are great too with very few rocks and sandy footings. If you stay in Ka'anapali you have to make the trip.
Unique spot on Maui's northwestern shore at the Maui Sheraton, the Black Rock can be accessed either from the high side (back of the Sheraton on the north side) or the beach. Snorkeling is out of this world, saw three eagle rays in formation off the end. Sunsets are spectacular and the event at dusk is not to miss. Beach is great, rock is great place to reflect especially early in the morning before the crowds. Not to miss if you visit Maui.
