Buck Island is THE reef to snorkel. We went on the half day tour and felt like we were in the hands of professionals.
Big Beard provides all the snorkel gear needed and takes the time to teach folks how to snorkel. Though I've snorkeled in many places taking a few minutes with my wife as she got comfortable I learned a few things about how to blow thru my mouth piece to ensure less carbon dioxide in the tube.
The reef and fishes are the best compared to other st. Croix locations.
On the way back a group of dolphins showed up and Michael the captain was willing to stop and stay with them as we all took pictures.
