I have been here many times and it is one of the best beaches on the big island. I have snorkeled here before and it is alright but the Kona side offers much better marine life, etc. But, the last time I went (3-04') I had the experience of a lifetime. There was a school of porpoise (or dolphins)...at least 100-150 right off shore. There were about 15 people and we swam with the school for a couple of hours!!!!! It was really a great experience and I'm told that they come play/feed off the beach here occasionally. I went back two more times on this trip, but did not see any signs off them. Good Luck, Aloha.
