I have snorkeled here 3 or 4 times and scuba dove here yesterday. If you do not follow one of the sandy channels out, this place is dangerous. The coral is inches under the water sometimes and swimming over it (especially with scuba gear) could cause injury to you and the corals. The visibility was not that great. Even 200 yards off shore it was still pretty bad. To be fair, if there is good visibility and calm seas, I can see this as being one of the best snorkeling sites in Maui.
