The Motu at Bora Bora is pretty basic and while there is some snorkeling there, it is not comparable to the amazing snorkeling at the motu in Ta'ahaa!! I would suggest renting a boat to take you around bora bora. When we were there i found a charter at the docks, where the tender arrives who took us around bora bora on a private boat for 2 hours for $225 USD. He even took us to his private island!! Much less expensive than the $950 excursion offered from the PG. Have fun.
