It's a bit of a wade/swim out to the best snorkeling, but well worth it. I circled the large rock twice, and while strenuous it was worth it. We saw multiple turtles, rays, and large schools of fish. Food was pretty decent. Try the Bushcrack and Sands beer, they're pretty good.
As with any snorkeling destination, I would suggest bringing your gear because the gear provided is not in the best shape.
