The story of a place
A Caribbean world above and below the water
Seen from above, Belize’s reef looks like an intricate drawing in blue: pale shallows, narrow islands and sudden passages into deep water. From a boat, the distinctions become practical. A sheltered snorkel site, an exposed reef edge and the Great Blue Hole offer very different experiences.
The reef deserves time for its living detail. Watch how fish use the spaces between coral heads and how seagrass, mangroves and open water fit together. The Blue Hole is a remarkable geological feature, but it is only one part of a much larger marine landscape.
The essential experience
Make time for this.
Take a carefully chosen guided snorkel or dive excursion with time to observe a healthy reef, then see the relationship between reef, cay and lagoon from the surface.
Explore the highlights
Look a little closer.
Look between Belize’s reef islands and the living coral structures beneath the water.
Reef edge
Notice the change from shallow turquoise water to the darker open sea.
Mangroves
Look at the sheltered water and root habitat without disturbing wildlife.
Coral structure
Watch the spaces between colonies as closely as the colonies themselves.
For the curious reader
History, landscape
and context.
The Belize Barrier Reef is a series of coral reefs straddling the coast of Belize, roughly 300 metres (980 ft) offshore in the north and 40 kilometres (25 mi) in the south within the country limits. The Belize Barrier Reef is a 300-kilometre (190 mi) long section of the 900-kilometre (560 mi) Mesoamerican Barrier Reef System, which is continuous from Cancún on the north-eastern tip of the Yucatán Peninsula through the Riviera Maya and down to Honduras, making it the second largest coral reef system in the world after the Great Barrier Reef in Australia. It is Belize's top tourist destination, popular for scuba diving and snorkeling and attracting almost half of its 260,000 visitors.

Turn curiosity into a visit
Plan your visit.
- Physical demands
- Choose between boat-based sightseeing, swimming, snorkelling and qualified diving. A deep dive is not necessary to appreciate the reef.
- The practical detail
- Choose the experience before choosing the famous photograph: a Blue Hole excursion and an accessible wildlife-rich snorkel day serve different interests.
