The Great Blue Hole, Lighthouse Reef & Turneffe Atoll Trips
Belize liveaboards offer tours including diving at Turneffe and Lighthouse reefs, featuring the famous Blue Hole. Lighthouse Atoll has no established accommodation options so the most practical means of diving at both of Belize's 2 premier destinations is by liveaboard safari.
Furthest from the mainland is the most easterly and best area for diving in Belize, the world renowned Lighthouse Reef. Great visibility all year round, critters galore, fantastic steep drop-offs and walls plastered with huge gorgonians can be found all along the eastern and southern side of the atoll. But perhaps the key attraction are the vibrant reef flats - jungle-like, swaying soft coral gardens that are cut with gullies and fissures and make ideal sites for divers to explore. Spotted eagle rays, barracudas and hawksbill turtles are frequently sighted at Half Moon Caye Wall and Que Brada. [More details on these dive sites: Lighthouse Reef].
Lighthouse Reef is home to The Blue Hole, a collapsed freshwater cave system approximately 1,000 feet across and over 400 feet deep. Most Belize liveaboard cruises include multiple dives on Half Moon Caye, another spectacular site where the wonderful visibility means great sightings in the blue of turtles, sharks and rays, as well as a lot of macro creatures to marvel at.

Turneffe Reef is the nearest of the 3 atolls to the mainland. The lagoon inside the mangrove covered islands that make up the atoll acts as an important nursery for reef fish such as snappers and groupers. It is also home to several pods of dolphins and manatees, which are sometimes seen. The surrounding waters are home to many of the larger fish species such as dog and cubera snapper, permits, horse eye jacks and black groupers. Dives here tend to be shallow but on healthy reefs teeming with life. The Elbow is the highlight here with schools of spawning fish congregating in vast numbers off the wall. The sight of a slowly swirling wall of large fish is enough to put a smile on the most world-weary of diver's faces. Other dive sites include the Front Porch, a great place for underwater photographers to snap pictures of Turneffe's endemic spotted toadfish. [More details on these dive sites: Turneffe Atoll].
Most trips are 7 nights (but there are some of 10 nights) and they are surprisingly affordable. The Belize liveaboard boats follow the same route so your choice of boat will be a judgement of price vs boat facilities/service/accommodation. Most of the dives are suitable for qualified divers of all levels of experience.

Glover's Reef & Placencia Trips
A few select Belize liveaboards venture south to Glover's Reef , a true Caribbean atoll that sees far fewer divers. Glover's Reef is one of only 4 true coral atolls in the Caribbean and holds UNESCO World Heritage Site status. The atoll's remote, protected position has kept its reefs exceptionally healthy. Diving from Belize liveaboards at Glover's Reef spans dramatic walls, shallow reef systems, and pristine coral formations. Visibility in the brilliant turquoise lagoon often exceeds 30 metres. Marine life encounters include Caribbean reef sharks, nurse sharks, eagle rays, sea turtles, green moray eels, batfish, seahorses, and the endemic white-spotted toadfish,. Notable dive sites include Shark Point, a remote spawning aggregation site for groupers where nurse sharks are common and blacktip, hammerhead, and even tiger sharks may appear.
The southern itinerary also includes Gladden Spit & Silk Cayes, world-famous for whale shark aggregations from March through June, when snapper spawn draws these gentle giants to the surface. Even outside whale shark season, the site delivers large schools of horse-eye jacks, bull sharks, and spawning groupers. The week concludes at Laughing Bird Caye, a UNESCO site featuring faro-shaped reefs, crystal-clear shallows, and colourful coral gardens.
These Belize liveaboard trips run as 7-night charters, typically departing from Placencia on Saturday evening, and suit divers of intermediate to advanced levels. The depth range is 8 to 33 metres, and the region's relative isolation means fewer dive boats and quieter reefs, but it also requires comfort with occasional drift conditions and deeper wall profiles. For those who have already dived the northern atolls and seek something less travelled, Belize liveaboards that include Glover's Reef offer a genuinely different diving experience, more remote, more pristine, and equally rewarding.
