Scuba Diving Ambergris Caye: 6 Belize Barrier Reef Dive Sites (Photos + Tips)

Scuba Diving Ambergris Caye

While staying in San Pedro on Ambergris Caye in Belize, we completed six dives along the nearby Belize Barrier Reef, which is part of the second-largest reef system in the world. All six of the dive sites were just a short boat ride away from the piers in San Pedro, making it easy to explore different sections of the reef over several days.

In this post I’ll share the six dive sites we explored, the kinds of marine life we saw (including a bucket list animal that I have been waiting to encounter underwater!), and what the reef conditions were like. 

If you’re planning a trip to Ambergris Caye and wondering what the diving is actually like, you’re in the right place! 🙂 

Ambergris Caye Dive Sites 

While visiting San Pedro in late February we did three days of two-tank dives, exploring several canyon-style dive sites known for their swim-throughs, reef sharks, and steep walls of coral. 

Michael from Blue Heaven Dives was our wonderful dive guide and David from Belize Magical Adventures was the boat operator. 

Each of the six dive sites was a 5-8 minute boat ride from the pier in San Pedro, and the max depth we reached for all dives was between 80-100 feet.

Dive 1: San Pedro Canyons — Ambergris Caye Dive Site

• Depth: 90 feet
• Visibility: Typically 100 feet (about 50 feet on the day we went)
• Highlights: Tall coral walls + a dolphin encounter during the safety stop

On our first day of diving along the Belize Barrier Reef, the conditions were a bit rough. Strong winds and big waves reduced the underwater visibility to around 50 feet (apparently it’s often 100+ feet here). Despite that, I loved this dive. Tall canyon-like coral walls created dramatic passages to swim through. As we began our ascent for our safety stop, a dolphin swam right past us. Meeting a dolphin underwater has been on my bucket list for awhile, so it was an exciting welcome-to-Belize-diving introduction. 

Dive 2: Esmeralda Canyons — Ambergris Caye Dive Site

• Depth: ~80 feet
• Visibility: Typically 100 feet (about 50 feet on the day we went)
• Highlights: Large school of yellowtail snapper, friendly nurse shark, deep, dramatic canyon

This was our second dive of the day, again with less-than-ideal visibility. As we descended, we passed through a school of fairly large yellowtail snappers. My ears gave me some trouble equalizing on this dive, so I wasn’t able to descend as deep into the canyons as I had hoped. Even so, we had a fun encounter with a nurse shark and spotted a reef shark cruising along the reef, along with clouds of tiny blue chromis darting between the coral.

Dive 3: Tackle Box Canyons — Ambergris Caye Dive Site

• Depth: 85 ft.
• Visibility: ~60 feet
• Highlights: Reef sharks, underwater landscape with swim-through tunnels, overhangs and caverns

The dramatic underwater landscape at Tackle Box made it one of my favorite dives of our Belize trip. The reef has canyons, caverns, and tunnel-like swim-throughs that made exploration here especially fun. We saw brain coral, soft corals swaying in the current, and a large school of small fish shimmering above the reef. We were lucky enough to spot several reef sharks on this dive—including one that swam surprisingly close.

Dive 4: Tuffy Canyons — Ambergris Caye Dive Site

• Depth: 50-80 ft.
• Visibility: ~60 feet
• Highlights: Sea turtle, friendly nurse shark, porcupine fish

At Tuffy Canyons, a mix of stony corals forms a reef with lots of crevices and hiding spots for lobster, urchins, and small fish. This was also where we met the most curious nurse shark of the trip. He would swim past us and then suddenly appear again, gliding just inches beneath us. “Puppies of the ocean” is a very fitting description of nurse sharks, especially this one. It was at Tuffy Canyons that we spotted our only sea turtle of the six dives, as well as my personal favorite–a porcupine fish.

Dive 5: “The Chimney” — Canyon Swim-Through near Esmeralda Canyons

• Depth: 100 ft.
• Visibility: 70 ft.
• Highlights: Dramatic, narrow passage with light spilling through the openings

This spot isn’t marked on most dive maps, so our guide, Michael, led us there from a nearby mooring—I believe it was somewhere near the Esmeralda Canyons area. It ended up being my favorite dive of the trip. We descended through a narrow coral passage our guide called “the Chimney,” dropping down between reef walls before entering a tunnel-like area where beams of sunlight streamed through cracks and openings above. The effect was incredible. As usual, we swam with reef sharks, nurse sharks, triggerfish, and schools of various types of fish. As we surfaced, we saw sharks circling a nearby boat where fishermen were chumming the water.

Dive 6: Mayan Princess — Ambergris Caye Reef Dive

• Depth: 90 ft.
• Visibility: 70 ft.
• Highlights: Overhangs and swim throughs. Curious nurse shark and bright sea sponge

Our final dive featured more beautiful reef structure, including overhangs and swim-throughs. A curious nurse shark kept appearing around us throughout the dive, while squirrelfish, angelfish, butterflyfish, and a barracuda hovered along the reef. A reef shark rounded a corner unexpectedly and came closer than any we had seen on the trip, before turning and gliding away.

Who Should Dive Here 

These canyon dive sites along the Belize Barrier Reef near Ambergris Caye are great for beginner to intermediate divers. 

If you’re a diver who enjoys spotting marine life like nurse sharks and reef sharks, YOU WILL LOVE these sites near Ambergris Caye, as those were the animals we consistently spotted. 

Most of the dives feature coral canyons, swim-throughs, and overhangs that make the underwater landscape especially fun to explore, while the depths remain within typical recreational limits (most of our diving time was spent between about 60-100 feet). 

If you enjoy diving without lengthy boat journeys, you’ll  appreciate that these dive sites are all less than a mile from the piers of San Pedro on Ambergris Caye. After just a five minute boat ride, and a backward roll entry from the boat, you’re underwater swimming with the nurse sharks.

Ambergris Caye Diving Logistics

Planning a dive trip to Ambergris Caye is fairly straightforward, but here are a few helpful things to know:

Getting there
Most travelers fly into Belize City, then continue on to Ambergris Caye either by a short flight or a ferry ride. We took the ferry, which means we first had to take a shuttle from the airport to the ferry terminal in Belize City, wait for our scheduled departure, and, finally, board the boat for the 1.5 hour ride to Ambergris Caye.

Choosing a dive operator
There are plenty of dive shops to choose from, especially around San Pedro. Many offer similar packages, so when choosing, consider group sizes, schedule, and online reviews. I chose Blue Heaven Dives and Tours based on their high reviews and small group sizes.

Is Diving Ambergris Caye Worth It?

If you’re wondering whether diving Ambergris Caye is worth it, here’s my honest take after multiple dives along the Belize Barrier Reef.

What I loved:

Dramatic underwater landscapes

The biggest standout for me was the scenery. The steep canyon walls made each dive feel dramatic and immersive. I often felt that the landscape itself was the main attraction.

The Chimney

The chimney was my absolute favorite. The way sunlight streamed through the openings above created one of the most beautiful underwater moments I’ve experienced.

Large Marine Life Encounters

While there weren’t many large schools of fish (something I usually love), Belize more than makes up for it with bigger marine life

Nurse sharks followed us like puppy dogs on almost every dive.

Reef and even bull sharks were common sightings.

Seeing a dolphin underwater (for the first time ever on a dive) was a huge highlight and something I won’t forget.

These encounters were exciting and a huge part of what made diving here feel special.

More Affordable than other top dive destinations

My most recent diving experience outside Belize has been in Hawaii (shore diving in Maui and Manta Ray Night Diving on the Big Island), and one thing that really stood out here is the cost. Diving in Belize is significantly more affordable, especially when it comes to dive packages and overall trip costs. It’s a wonderful option if you’re looking for great diving without the higher price tag.

Downsides:

More INvolved Travel Day

Getting to Ambergris Caye took us a full day of travel—a non-direct flight from Denver, followed by a shuttle to the Belize City ferry terminal, and then a 1.5-hour ferry ride. It’s not the hardest destination to reach, but it’s not the easiest either.

Fewer Large schools of Fish

I always love swimming through big schools of fish, and we didn’t see many during our six dives. That said, nearby Hol Chan (where we snorkeled on our last day) is known for more of that kind of experience, so it may be possible to find if you add Hol Chan to your dive sites.

Similar dive landscapes

While the dives were beautiful, many sites had a similar look and feel—especially the canyon-style walls. I personally loved the scenery (so this didn’t bother me) but if you’re used to highly diverse dive environments, this might feel a bit repetitive after several dives.

Tips for Diving Ambergris Caye

Bring a wetsuit if you get cold
Water temperatures are generally warm, and many divers wear just their BCD over a swimsuit. If you get chilly easily like I do, pack a wetsuit top or shorty wetsuit. I wore mine on our third and final day of diving, and it was the only day I didn’t get cold in the water. You can find a link to the wetsuit top I use on my “Snorkel Essentials” amazon storefront.

Stay on Ambergris Caye
This is probably obvious, but it wasn’t to me when I started planning our trip. Initially I looked for places to stay on Caye Caulker, the quieter, neighboring island that is known for being slower-paced. From what I could tell, dive operators there run trips to sites in front of Ambergris Caye, which adds extra boat time. Leaving from the docks in San Pedro on Ambergris Caye meant our boat rides were only 5–8 minutes to the dive sites—a huge convenience that I appreciated.

Snorkeling Ambergris Caye

On our fourth and final day we switched from diving to snorkeling and visited Hol Chan Marine Reserve (including Shark Ray Alley). If you’re wondering what snorkeling is like on Ambergris Caye, check out the post: Snorkeling Hol Chan Marine Reserve
