Blue Hole/The Great Blue Hole - Belize

Blue Hole/The Great Blue Hole is a boat accessible salt water dive site, located in Ambergris, Lighthouse Reef, Belize. This dive site has an average rating of 4.02 out of 5 from 65 scuba divers. The maximum depth is over 150ft/46m. The average visibility is 51-60ft/16-18m.

Spectacular dive inside a giant hole in the center of an atoll. Dropping down past 100 feet presents beautiful stalactites and other formations.

Famous landmark - Lighthouse Atoll, Belize. Huge underwater cavern with collapsed ceiling. Deep dive 100-150ft - swim thru stalagtites. Must descend thru reef sharks at about 60-80 ft. Not a lot of fish at depth, but cathedral like cave stuctures around perimiter. Bottom is at around 300+ ft. Must take boat (3+ hours from San Pedro, Ambergris Caye or 1 hour if staying on Turneff Atoll) to site. Surface interval at Lighthouse Caye with Red Footed Booby bird preserve. Very scenic. Most dive operators run weekly trips to the Blue Hole.

Once an above ground cave that has collapsed this spectacular deep blue circle is 1,000 feet in diameter and over 400 feet deep. The Blue Hole is located at Lighthouse Reef, which is one of Belize’s three coral atolls.

Visibility when first entering the water is not that great and the water has a gray color to it but once you have dscended past the thermocline at 50 or 60 ft the water clarity will improve dramatically. This dive is not about the fish and coral formations you are used to seeing it is the stalactites you are going to see. Once you reach the 100 ft mark you will entire the first under cut where you begin swimming between these formations. Even though the water is clear
light is limited so for the best experience bring a dive light, this will help you spot the invertebrates and sponges that live here.

Often times if you look below you will spot sharks swimming in the hole which is probable the only fish you will see in side the Blue Hole. The reef around the edge of the hole has some coral growth and sea life but nothing compared to the reefs on the outer edge of the atoll because the water flow here limited.

Great once in a lifetime experience for the diver who wants to travel the world checking out new spots! It’s almost surreal. Not much sea life though.

What a dive! Nothing really to see but the suspense of dropping into a deep dark hole in the middle of the ocean! We did see about 10 reef sharks. They were nice enough not to eat us for lunch!

This is a bucket list dive but not sure I’d do it a second time. 2 1/2 hour boat ride for five minutes at depth (130-140 feet). Lots of large Caribbean reef sharks around 80 feet but not much other fish life. The cave was impressive, tho!

Awesome dive experience! ....not much for color, but the stalactites & stalagmites are ominous and spectacular! And the other dives (Re: Halfmoon Cay wall; The Cathedral) you do while you’re out there on the outter reef make it a no-brainer to dive the Blue Hole! It was also the only dive so far where I’ve felt the effects of nitrogen narcosis, which just amplified the wonder of the whole experience!

Nice dive, however, more to see at some of the other dive sites in Belize

I went scuba diving here on 8/24/2012. Average viz: 31-35ft/9-11m. Water temp: 76-80°F/24-27°C.
Very cool, definitely worth it. I’m a newish diver, so I was worried about it being too advanced for me, but it was no big deal. Very fun to swim among the stalactites, plus there were a ton of sharks! Maybe a dozen reef sharks, even a bull shark or two. Visibility wasn’t great, though.

This was a fun dive and the deepest dive I’ve ever had. 8 minutes at 140 ft.
