I just dove this site in Oct of 2001. If looking at the Arial picture, we entered the water to the left of the last little clump of trees on the left. There was a little boat tucked into the trees at that clump. A long snorkel in and out will save air, but can get tiring if it is choppy. The coral formations along the top of the wall are incredible and in about 20 feet of water so still plenty visible if snorkeling. The depth begins to drop to well over 200' so plan accordingly. Best bet is to check the current when you get to the edge and start your dive into it. Have fun.
