Belize Barrier Reef: Diving & Snorkeling Paradise 2025
The Belize Barrier Reef, a UNESCO World Heritage Site, stretches over 300 kilometers along Belize’s coastline and forms part of the second-largest barrier reef system in the world. Pristine waters, vibrant coral formations, and rich marine biodiversity make it a true paradise for divers and snorkelers.
Geographic Extent and Structure
The reef spans from the Mexican border in the north to the Gulf of Honduras in the south. It comprises three major atolls—Turneffe, Lighthouse, and Glover’s—and countless cayes (small coral islands) that serve as vital habitats for numerous marine species.
Coral Atolls and Cayes

Turneffe Atoll: Renowned for its deep walls and historic shipwrecks, offering thrilling dive experiences.

Lighthouse Reef Atoll: Home to the famous Great Blue Hole, as well as expansive shallow areas ideal for drift dives.

Relation to the Mesoamerican Reef
