If you dream of diving into a giant, perfectly round sinkhole surrounded by turquoise waters and teeming marine life, then Belize’s Great Blue Hole belongs on your bucket list. As one of the most iconic dive sites on the planet, it offers a breathtaking experience for adventurous divers looking to explore its deep blue mysteries.

  Where is the Blue Hole

Located about 60 miles (97 km) off the coast of Belize in the Lighthouse Reef Atoll, the Blue Hole is an underwater sinkhole that’s roughly 1,043 feet (318 meters) across and over 400 feet (124 meters) deep. From the air, it appears as a perfect navy-blue circle contrasting sharply with the lighter turquoise shallows surrounding it — a view so striking it’s been named one of the most beautiful sights on Earth.

  Why Dive the Blue Hole

The Blue Hole isn’t just about the unique geology — it’s about the surreal experience of descending into its cool, dark depths. As you drop past 100 feet (30 meters), massive limestone stalactites appear — remnants of an ancient cave system that collapsed thousands of years ago when sea levels rose.

You may also encounter:
? Reef sharks
? Midnight parrotfish
? Hammerheads (occasionally)
? Groupers and other deep-water species

The eerie silence, combined with the towering formations and endless blue, makes it a truly unforgettable dive.

  Tips for Divers

✔️ Best for experienced divers — most tours recommend having at least an advanced open-water certification due to the depth.
✔️ Dive operators usually combine the Blue Hole with other nearby sites like Half Moon Caye and Long Caye Wall for a full-day trip.
✔️ Bring or rent appropriate gear for deep diving and watch your no-decompression limits carefully.

  Best Time to Dive

While Belize’s diving season runs year-round, the best conditions are typically from April to June, when the water is calm and visibility is excellent.

  Make the Most of Your Trip

After your dive, don’t miss exploring:
– Ambergris Caye & San Pedro for lively island vibes
– The Belize Barrier Reef for colorful, shallow dives
– The charming town of Placencia for laid-back beaches
