Dave and Terry's Snorkeling Adventures Boca Chica Bay Boca Chica Bay has a mile of beach to walk. You can find a lot of interesting people to talk to, vendors selling their wares, and a variety of food. Dominican Republic Snorkeling in the Dominican is interesting, but you'll need to go by boat in this area. The attraction is that the Island is rich in culture.
Local buses are very inexpensive and a great way to meet the locals.
You won't have to look very hard for a guide. They will approach you. Plan to spend the day. The sea cucumber belongs to the starfish family. We saw this one washing in close to the beach.
