Discover the breathtaking underwater world of Belize on a liveaboard diving adventure. With the second-largest barrier reef in the world, iconic dive sites like the Great Blue Hole, and an abundance of marine life, Belize offers an unparalleled diving experience. Liveaboard diving allows you to access remote sites, maximize your dive time, and immerse yourself in the beauty of this Caribbean paradise.
Top Belize Liveaboard Diving Sites
Belize’s waters are home to some of the most spectacular dive sites in the Caribbean. A liveaboard trip gives you access to these remarkable locations, many of which are too remote for day trips from the mainland.
The Great Blue Hole
This iconic famous Blue Hole is a giant submarine sinkhole measuring over 300 meters across and 124 meters deep. Created when sea levels rose after the last ice age, this unique geological formation offers divers the chance to explore massive stalactites and limestone formations. While diving here, you might encounter Caribbean reef sharks and nurse sharks patrolling the deep blue waters.
Lighthouse Reef
Lighthouse Reef is the most easterly atoll in Belize and home to some of the best wall diving in the world. The reef’s dramatic drop-offs plunge from 10 meters to over 900 meters in depth. Sites like “The Aquarium” live up to their name with an abundance of colorful fish, while “Long Caye Wall” offers breathtaking swim-throughs and caverns teeming with marine life.
Half Moon Caye
Located within Lighthouse Reef, Half Moon Caye offers some of the most diverse diving in Belize. The “Half Moon Caye Wall” features a sandy stretch laden with garden eels and stingrays that gently slopes toward numerous swim-throughs and tunnels before reaching a dramatic drop-off. “Painted Wall” is known for its colorful spur and groove formations hosting parrotfish, black durgeon, and queen triggerfish.
Turneffe Atoll
Turneffe Atoll is the largest and closest of Belize’s three atolls, forming a series of mangroves and offering excellent drift dives. “The Elbow” at the southern tip is famous for its strong currents that attract large schools of jacks, snappers, and the occasional hammerhead shark. This diverse ecosystem combines reef, wall, and mangrove diving in one location.
Glover’s Reef
The most remote and least visited atoll, Glover’s Reef offers more diversity and fewer crowds. With over 80km of fringing reef and walls ranging from 7 to 900 meters in depth, it’s an exciting dive with many underwater photography opportunities. Look for goliath grouper, schools of horse-eyed jacks, Atlantic spadefish, eagle rays, and turtles in this pristine environment.

“Belize diving is always amazing. I especially loved the night dives – the critters really come out. The lobsters were walking around like they wouldn’t be delicious with butter, and the tarpon were jerks practicing their jump scares. We saw sharks, turtles, stingrays, eagle rays, eels, octopus… pretty much everything was in abundance.”
Best Time for Belize Liveaboard Diving
Belize can be dived year-round, but certain seasons offer different advantages depending on your preferences for weather, visibility, and marine life encounters.

- Dive Computers: Essential for monitoring depth and bottom time, especially for multiple daily dives
- Surface Marker Buoys: Recommended for all dives, especially at sites with boat traffic

Packing Essentials
- Exposure Protection: 3mm wetsuit is typically sufficient (water temperatures 26-30°C/79-86°F)
- Dive Light: Essential for night dives and exploring crevices

Environmental Responsibility
Belize’s marine ecosystems are fragile and require protection. As divers, we have a responsibility to minimize our impact and help preserve these underwater treasures for future generations.
Sustainable Diving Practices
- Maintain proper buoyancy control to avoid touching coral
- Keep a safe distance from marine life (minimum 3 meters/10 feet)
- Use reef-safe sunscreen without oxybenzone and octinoxate
- Participate in reef clean-up dives when offered
- Choose operators with strong environmental policies
- Report environmental concerns to dive guides and local authorities
- Support marine conservation organizations working in Belize
Practices to Avoid
- Touching or standing on coral, even if it appears dead
- Chasing, touching, or feeding marine life
- Collecting souvenirs like shells, coral, or other marine items
- Using gloves (encourages touching and can transfer bacteria)
- Wearing chemical sunscreens harmful to coral
- Creating excessive noise underwater that can stress marine life
- Leaving any trash or debris in the ocean
“The best way to enjoy Belize’s underwater world is to leave only bubbles and take only memories. The country’s marine reserves are working hard to protect these ecosystems, and as visitors, we have a responsibility to support these efforts through responsible diving practices.”
