If you are interested in conservation, ask for directions to GVI Global Vision International who are now located 35 km North of the town in Uvero.. This is the base for marine conservation work carried out by a young and enthusiastic group of full-time staff with the help of 16 volunteer divers, in liaison with Mexican partner organisations. Staff and volunteers are from around the world; they will be happy to tell you about the project and how you can become a volunteer yourself. Food and living conditions are basic but the experience is unbeatable.
The barrier reef, which is part of the Meso American Reef, just off shore offers opportunities for snorkeling or scuba diving, and keeps the waters of the Caribbean safe for kayaking. This reef is the 2nd longest barrier reef in the world being just over 900 km long, starting at puerto Morelos in Mexico, stretching down past to Belize to terminate at Honduras. A few of the dive operators are Dreamtime Diving (http://www.dreamtimediving.com) who also provide accommodation and Nomad Divers (http://www.nomaddivers.com).
