Belize is home to some of the finest scuba diving in all of the world. The Cayes (pronounced keys), the offshore atolls, and the barrier reef are the main attractions in Belize. The barrier reef, which is 185 miles long, is the longest in the Western Hemisphere, and second largest in the entire world. The cayes are coral sand and/or mangroves islands, that are located between the mainland and the barrier reef, on the barrier reef, and on or within the reef perimeters of the offshore atolls.
Tons of amazing dive sites to choose from
Over 50 dive sites accessible from San Pedro, on Ambergris Caye. Most of the best sites are conveniently located no more than a 10-20 minute boat ride away from San Pedro.
Belize is blessed with a diversity of reef systems which can be fully explored: from the distinctive topography of the Barrier Reef, to the offshore walls of the Turneffe, Glover’s and Lighthouse atolls, and last, but certainly not least, the magnificent Blue Hole.

The Belize Barrier Reef
Home to Belize’s most prestigious natural treasure, the world’s second largest living barrier reef at roughly 185 miles/298 kilometers in length, located just off its’ eastern shore, Ambergris Caye is a true diver’s haven.
The reef crest is well defined by a conspicuous line of breaking water that is clearly visible from the shore and at low tide, Staghorn and Elkhorn coral can even be seen protruding above the surface. Over 35 of Belize’s most spectacular dive sites are within close proximity and are accessible by boat via a series of natural channels that traverse the reef crest to the open water beyond.
Dives extend to depths of between 60 and 80 feet where mazes of lobster and Black drum inhabited spur and groove canyons can be intricately explored. Large groupers evasively linger around go-by cleaning stations while turtles and spotted eagle rays make sudden appearances by scurrying over the edges of oncoming canyons. The vibrant waters are also home to a multitude of shark and dolphin species. Swim-through caverns and tunnels provide more adventurous diving venues where divers may exit through sporadic chimneys to discover that they are in a totally different location from where they primarily entered.
Must Do Local Dives
The Hol Chan Marine Reserve and Shark Ray Alley are the most popular diving/snorkeling sites in all of Belize. The large amount of fish life found with the Hol Chan “cut” accessible by snorkelers and divers, the diversity of marine life encountered throughout the 4 zones of the park and the excitement and novelty of swimming with large numbers of nurse sharks and sting rays making this an experience not to miss.
Due to the protected status of the Hol Chan Marine Reserve, the fish populations have exploded. Divers can swim from one side of the cut to the other, experiencing shallow reef, drop offs over the steep sides of the “cut”, and seagrass and sand beds in the middle of the channel. Outside the barrier reef, the ocean bottom gently slopes off into the Caribbean. All levels of diving can be accommodated here due to the variations in depth; from 30 to over 100 foot dives can be planned and executed. Spur and groove formations (hills of coral running parallel to valleys of sand) provide rich habitat for marine life. Spotted eagle rays and other pelagic creatures swim above the reef while the more cryptic life like lobsters and eels fill the holes and tunnels through the coral spurs.
SKIN DIVER MAGAZINE has selected Shark Ray Alley as one of the seven best “animal dives” in the Caribbean. For years, local fishermen cleaned their catch just inside the reef, to the south of Hol Chan Cut and Ambergris Caye. The fishermen soon noticed that the offal from cleaning fish was attracting Nurse Sharks and several Southern Sting Rays. The sharks and rays hear the dive boats approaching and begin to school in anticipation of bait being thrown into the water.
When you arrive, you will see the surface often boiling with rolling sharks and stingray wings as they vie for the scraps. These creatures have a great tolerance for divers and snorkelers. The rays, which have a ‘wing-span’ of two to four feet, swim directly towards the divers, mouths often turned up hoping for a hand held tidbit to be placed near their mouths. Others have learned to swim in circles around the divers, as if performing for food. The docile Nurse Sharks average four to six feet in length and can be a bit more aggressive than the stingrays. The abundance of marine life along the barrier reef is remarkable. It is not usual to see a school of porpoises or turtles. Spotted eagle rays are often seen in groups of three or four, while the rare manta rays usually travel alone. Schools of amber jacks a lone barracudas commonly swim in the open waters away from the corals. Come experience the underwater wonders of Belize. The largest living barrier reef in the world is host to a variety of species including sharks, rays, eels, groupers, parrot fish, trigger fish, sea horses, turtles, shrimp, sea fans, coral and many other wondrous aquatic life.

The World Famous ‘Great Blue Hole’
Six miles north of Halfmoon Caye, in the lagoon of Lighthouse Atoll, is the Great Blue Hole. The name alone will make it different from some of the other “blue holes” to be found in the Caribbean. This one is the largest, deepest, and most famous. Thousands of divers have made it the reason they have come to dive in Belize.
Jacques-Yves Cousteau who declared it one of the top ten scuba diving sites in the world made this site famous. In 1971 he brought his ship, the Calypso to the hole to chart its depths. The Great Blue Hole was formed sometime during one of the ice ages that covered the North American continent several millions of years ago. At this time it was dry and because of its limestone makeup, stalagmites and stalactites were created drop by drop of limestone rich water. Some of these stalactites are nearly thirty feet long and nearly eight feet in diameter.
The top edge of the Great Blue Hole is nearly 1,000 feet across and is ringed by fringing coral that makes for an excellent snorkeling adventure. The base of this fringing reef gradually slopes at about 40 degrees until at a depth of 50 feet it suddenly drops into the Great Blue Hole. A sheer, pockmarked wall, covered in some places with algae called Halimeda, is the only reference as descent is initiated. Most of the time there will be a slight thermocline felt at around 90 feet and at this point the visibility will improve substantially. The stalactites start at a depth of 120 feet and are plainly in view at the limits of sport diving, 130 feet.
This amazing geological formation is not home to a variety of marine life, especially at depth. On occasion, you will see groupers, sharks, horse-eye jack, squirrel fish back up in a nook, and even schools of Reef Sharks. This really does make for an eerie, almost surreal setting.

Turneffe Atoll offers true world class diving — the visibility often ranges from 100 to 150 feet. The diving sites are considered some of the best in the Western Caribbean. Turneffe Atoll is the only Caribbean Atoll made up of dozens of mangrove islands, which are the juvenile nurseries for coral reefs, and also means many schools of fish. The largest of the three atolls located off the country of Belize, Turneffe is made up of 200 plus islands. It is 32 miles long and at its widest point is nearly 10 miles wide. Due to its proximity to the mainland, one would think that the diving there would be more utilized, but in fact, Turneffe is the “forgotten atoll”. Dive operators cruise by it on the way to its more famous neighbor Lighthouse Atoll, home of the Great Blue Hole and Halfmoon Caye.
For this very reason, Turneffe has some of the most pristine diving to be found, with over 70 dive sites. This means that in nearly any weather a fantastic dive site can be found. The many mangrove islands that make up the atoll are a tremendous nursery, which nourishes many different species of juvenile marine life. This unique biological situation causes the Turneffe Atoll to have some of the most prolific marine life in Belize.
The sites on the northwest side of the atoll average depths on the top of the wall between 30-45 feet with wide spur and groove formations and vertical wall dropping in excess of 100 feet before shelving and dropping again into the deep. An abundance of marine life including schools of Cubera Snapper and diverse population of grouper including Nassau, Tiger and Yellow fin grouper are present. Reef tropical too numerous to count and resident populations of the dainty Spotted Drum and the spectacular Splendid Toadfish are seen regularly. If you keep your eyes sweeping the deep water watch for sightings of Spotted Eagle Rays, Turtles and Sharks including the rare but exciting sightings of Manta Rays and Hammerhead Sharks. This side of the Atoll is protected from periodic bouts of strong easterly and southeasterly winds making it a well protected and ideal dive condition in most weather situations.
The versatility of diving on the Turneffe Atoll is unparalleled. The wall on the east side of the Atoll tends to start a bit deeper in the 45-50 foot range and generally has narrower spur and groove but a sheerer wall face than the west side of the atoll. Sightings of pelagics such as rays, turtles and sharks as well as reef tropical and numerous stands of Yellow Tube Sponges can be seen while diving on the east side of the atoll.
Glover’s Reef Atoll is the least known and least dove of Belize’s three atolls. The atoll was named after John Glover, a famous pirate who resided here and who used the remote islands as the base for his raids against Spanish galleons heading to and from the Bay Islands of Honduras. Many cannon balls have been found from his battles with the Spanish fleets. At least 4 sunken ships are located in this area. Although the least known, Glover’s is the atoll that most resembles a “classic” Pacific atoll. There is over 72 miles/ 116KM of reef, many with drop offs starting as shallow as 25 ft/7.5m and continuing down to over 7000ft/2134m, an incredible sight to see. Glover’s is often rated as one of the top 5 dive sites in the world. With an abundant wildlife that includes everything from juvenile spotted drums to manta rays. After diving Glover’s, we’re sure you will agree it is not a site to be missed.
Rising out of the blue from a depth of well over 2,000 feet this well defined oval shaped coral formation surrounds more than 700 patch reefs inside its 100 square mile crystalline lagoon. Of the three atolls Glover’s Reef sees the least amount of human contact and is largely unexplored. Come see for yourself why this atoll was recently designated a National Marine Reserve and, in 1997, a World Heritage Site by UNESCO.
Belize possesses three of the four atolls found in the Western Hemisphere. The origin of these Atolls: Lighthouse Reef, Glover’s Reef and the Glover Islands are all distinct anomalies in the Caribbean. Nothing else in the Western Hemisphere resembles a true coral atoll. According to geologists they are even more unusual in that the origin of their formation does not seem to mirror the atolls of the Pacific Ocean, where rings of coral are better known.
The ancient processes contributing to Belize atoll development may have begun as many as 70 million years ago and the atolls did not develop around subsiding volcanoes. Instead, they originated atop giant fault blocks; limestone covered ridges that settled in steps, providing a series of offshore platforms for coral growth. After the last ice age, with the slow rise of sea level, coral growth continued upward, creating the precipitous outer walls and the shallow inside lagoon that typifies these distinct formations. Many drop-offs surrounding the Belize atolls are thousands of feet deep, while depths in the shallow lagoons average 10 to 30 feet.
