With direct access to the thriving coral reefs of the Mesoamerican Barrier Reef - the second-largest barrier reef system in the world - Belize is an incredible destination for scuba enthusiasts. Divers can immerse themselves in a dazzling underwater world, coming face-to-face with majestic whale sharks, graceful sea turtles and schools of eagle rays as they glide effortlessly through the turquoise depths.
Stretching for hundreds of kilometres, the Mesoamerican Barrier Reef is a true hotspot for marine life, boasting an incredible diversity of dive sites that cater to all skill levels. From near-vertical walls encrusted in a kaleidoscope of corals to patch reefs interspersed with sandy channels and gently swaying seagrass beds, the diving in Belize is exceptional, to say the least.
With over 500 species of fish, 60 species of coral and 350 species of molluscs calling this region “home”, the marine life of the Mesoamerican Barrier Reef is nothing short of astounding. Critically endangered species such as sea turtles and goliath groupers can be found here, together with the largest population of manatees in the western Caribbean. Belize also hosts one of the world's largest known aggregations of whale sharks and seeing these massive creatures in their natural habitat is not to be missed.

After the sun goes down, the waters surrounding Ambergris Caye come alive with a dazzling display of bioluminescence - millions of tiny glowing microorganisms that cast an otherworldly neon blue glow.

Lighthouse Atoll
This isolated atoll faces the open expanse of the Caribbean Sea, with sheer drop-offs that descend over a thousand metres below the surface. It is in this dramatic, oceanic environment that visitors are most likely to catch a glimpse of the larger marine life that inhabits Belize’s offshore waters, such as the graceful reef sharks that patrol the perimeter of Lighthouse Atoll.
Not to miss is the legendary Great Blue Hole - a colossal, 300-metre wide and 125-metre deep collapsed limestone cavern that was formed thousands of years ago. Divers venturing into this almost perfectly circular sinkhole will encounter dramatic overhangs, submerged stalactites and a distinct thermocline that separates the warm surface waters from the cold, nutrient-rich depths below.
While larger marine life is scarce within the confines of the Blue Hole itself, curious reef sharks and the occasional bull shark have been known to investigate the perimeter, lured by the possibility of an easy meal. For those willing to make the journey out to this remote oceanic outpost, Lighthouse Atoll offers a truly unforgettable window into Belize's astounding marine wonders.
Turneffe Atoll
Situated just a short boat ride from the mainland, Turneffe Atoll is home to stunning geological formations and a vast array of marine life. Scuba diving here will see you rewarded with awe-inspiring encounters, from the presence of eagle rays gliding overhead in graceful squadrons to massive moray eels lurking within crevices.
Turneffe Atoll also teems with schools of shimmering jacks and snappers congregating along the reef's edge and is one of the best places to spot tarpon, one of Belize's most celebrated fish. Those with a keen eye will also be delighted to spot delicate seahorses and peculiar white-spotted toadfish, as well as an impressive array of sea slugs and industrious cleaner shrimp.
One of Turneffe's most renowned sites is known as "The Elbow," where the reef takes a dramatic twist and plunges into dizzying drop-offs. For experienced divers, it offers unforgettable experiences that showcase the sheer geological dynamism of this remarkable underwater world.

Offering all-inclusive packages, Shaka Caye is the ideal Belize dive resort for guests who want to pay once and then not think about money but simply enjoy their vacation.
Glover’s Atoll
As the most remote and least visited of the country's coral atolls, Glover’s Atoll lies nearly 50 kilometres offshore from the town of Placencia. Those who make the journey here are rewarded with some of the most awe-inspiring and uncrowded dive sites in all of Belize, if not the entire Caribbean region.
The atoll's near-vertical walls plunge dramatically into the inky blue depths, their surfaces dotted with caverns, overhangs and other fascinating formations. Towering pinnacles, some reaching heights of over 30 metres, rise towards the water's surface, with parrotfish, angelfish and countless other fish species darting between the coral.
The proximity of Glover’s Atoll to the Bartlett Trough - a deep ocean trench stretching all the way to the Cayman Islands - means that larger pelagic creatures like whale sharks and reef mantas are frequent visitors. When diving here, you should keep one eye trained on the blue water beyond the reef, as you never know what may suddenly appear.

Gladden Spit and Silk Cayes Marine Reserve
Located just off the coast of Placencia, Gladden Spit is renowned as the premier whale shark hotspot in Belize. Between the months of March and June each year, these gentle giants make their way to this unique underwater ecosystem to take advantage of a natural phenomenon - the synchronised spawning of around 30 fish species.
Drawn by the abundance of nutritious fish eggs and larvae, large numbers of whale sharks can be spotted in the waters around Gladden Spit and the Silk Cayes Marine Reserve. This creates an unparalleled opportunity for divers and snorkellers to encounter these magnificent animals in their natural habitat. To maximize your chances, it's best to time your visit around the new moon when the fish spawning reaches its peak.
Aside from its whale shark sightings, the Silk Cayes Marine Reserve protects some of the healthiest parts of the Mesoamerican Barrier Reef, largely due to its elevation and the good quality of the water here. The area’s sandy beaches also serve as nesting sites for hawksbill turtles and seeing these critically endangered creatures is a highlight of any visit.

Best time to dive in Belize
The peak tourist season in Belize is from December through April when the weather is at its driest and most pleasant. During these months, daily temperatures average a comfortable 26°C (78°F), with refreshing breezes that can occasionally pick up into more powerful gusts, particularly in the afternoons and evenings.
This is an ideal time to dive in Belize as the calm, clear waters offer excellent visibility of up to 30 metres (100 feet). Water temperatures remain remarkably stable, fluctuating only slightly between 27-30°C (80-86°F), so a lightweight shortie or skinsuit is typically all that's needed to stay comfortable underwater.
The rainy season runs from June through November, bringing daily downpours and an increased risk of hurricanes between August and October. This can lead to lower visibility due to coastal runoff, as well as choppier surface conditions. But for those willing to brave the weather, the rewards can be great - May in particular is an excellent time to visit as whale sharks are migrating through the area.
