Turneffe Atoll is a large coral atoll off the coast of Belize and is the largest of the country’s three atolls. It is known for extensive reef systems, mangrove cayes and a central lagoon that together support diverse marine life.

The atoll is a major destination for scuba diving, snorkeling and sport fishing because of its reef walls, patch reefs and channels. Operators run liveaboard and day trips from mainland Belize to dive sites and lodges on the cayes.

The area was designated as a protected marine reserve to conserve reef and mangrove habitats and to manage fishing and tourism activities.

Turneffe Atoll sits in the Caribbean Sea east of mainland Belize and is accessed by boat or liveaboard vessels from Belize City and other coastal ports.

  • Marine reserve: The largest of Belize's offshore atolls and a designated marine reserve, the area supports coral reefs, mangroves and seagrass habitats that are important for diving and fisheries.

How to Get to Turneffe Atoll #

Tips for Visiting Turneffe Atoll #

  • Book dive or snorkel trips with operators certified by Belize's Fisheries Department and ask about Turneffe Atoll zoning-some areas are strictly no‑take.
  • Bring reef‑safe sunscreen and a light rashguard: sun reflection off the water is brutal and exposure adds up fast.
  • If trying to see manatees, coordinate with a lodge or guide who knows the shallow mangrove channels; sightings are seasonal and never guaranteed.
