Up to five huge green sea turtles came to feed at Black Rock. We saw them almost every time we went to snorkel, at 7 am and 4 pm, most days. There were numerous unicorn fish, triggers, filefish, cornets, and goatfish. Saw a couple of eels and a barracuda; no sharks, no rays. The crowds can be bad even though we were there at low season but you can swim around them out to the cove around the point. Luckily surf was low so we snorkeled whenever we wanted to and visibility was good. We saw more turtles at Black Rock than at Turtle Town. We really enjoyed staying at the Kaanapali Beach Hotel, next to the Sheraton so could walk there easily.
