Update: The Reef is Safe!
We are pleased to announce that on September 11, 2025, SEMARNAT officially revoked the Environmental Impact Assessment (EIA), citing significant environmental risks to the Villa Blanca Reef. Cozumel’s 4th cruise pier was effectively stopped due to legal and environmental pressures.
Just off the western coast of Cozumel lies one of the island’s most beautiful yet vulnerable underwater treasures — Villa Blanca Reef. A favorite among local dive professionals and visiting underwater explorers, this reef offers an unforgettable experience filled with color, life, and purpose. But today, its future hangs in the balance.
A Reef with Three Unique Faces
1. Iron Shore Reef – A Snorkeler’s Delight
This shallow reef lies just south of the Sand Dollar Sports Dive Center and is a fantastic spot for both snorkeling and swimming. With a maximum depth of only 10 to 15 feet, it’s easily accessible for all skill levels.
The reef is home to a rare and critically endangered elkhorn coral, making it a special place for nature lovers. You’ll also find plenty of curious sergeant majors swimming alongside you in the crystal-clear water.
It’s a safe and enjoyable location for both children and adults to explore the ocean’s beauty.
2. The Shallow Section – Where Hope Begins
Located directly offshore from Sand Dollar Sports, the shallowest part of Villa Blanca Reef is accessible right from the beach. It ranges from 10 to 30 feet in depth. This is the heart of our Coral Reef Restoration Program, where coral fragments are carefully grown and planted onto degraded reef patches. There are also dozens of reef balls, the Zoe Living Sea Sculpture, and multitudes of coral reef platforms. Our newest project involves growing elkhorn and staghorn corals from fragments that were collected from the reef. These corals are critically endangered and have almost disappeared from Cozumel.
This reef is also home to seahorses. The longsnout seahorse (Hippocampus reidi) is found hiding in the many sponges and algae that make up a large portion of this reef. They come in a variety of colors, including black, reddish-brown, orange, red, and yellow. If you don’t mind a slow dive among the sponges and algae, you just find one!
Snorkelers and divers can witness conservation in action — gorgonian fan corals swaying in the current, juvenile fish weaving through coral heads, and marine interns monitoring coral growth and biodiversity. It’s not just a dive — it’s a living classroom and a symbol of hope.
3. Villa Blanca Wall – A Deep and Dramatic Dive
Further offshore, the reef drops off into the Villa Blanca Wall, a spectacular dive site for experienced divers. The dive depths here range from 50 to 130 feet (the deepest point is 600 feet!). The wall can have strong currents that can change direction, but often they run south to north.
This sheer coral and sponge-covered cliff is filled with giant basket sponges, gorgonian corals, a variety of triggerfish, schools of jacks and yellow grunts, flounders, groupers, angelfish, as well as moray eels hiding in crevices. During eagle ray season (December – March), you might see a few eagle rays as well! Loggerhead turtles have also been spotted on this reef.
Villa Blanca Reef at Risk: The Threat of the Fourth Pier
Despite its beauty and biodiversity, Villa Blanca Reef is now under threat. The proposed construction of Cozumel’s fourth cruise ship pier, which is now on hold, would be located on top of this fragile ecosystem.
If the project proceeds, Villa Blanca faces:
- Dredging and sedimentation that would smother coral colonies
- Destruction of corals, sponges, and marine habitats–and our coral reef restoration projects
- Construction runoff and marine pollution
- Disruption to marine life migration and spawning
Because Villa Blanca lies outside the official Marine Park, it receives less legal protection — making it even more vulnerable to development. And this is why conservationists are working hard to make this a protected area to protect it for all ages to come.
Why You Should Dive Villa Blanca Reef Now
We invite you to dive Villa Blanca Reef now — while it’s still thriving, and while your presence can make a real difference. By diving with Sand Dollar Sports, you’re not only supporting a local dive operator — you’re directly helping to protect this reef. We donate a portion of all profits to fund our ongoing coral restoration efforts, and every dive helps fund science, education, and coral planting.
We are proud to be recognized as one of the most sustainable dive centers in Cozumel. Our credentials include:
Sustainability isn’t a trend for us — it’s our way of life. We believe that every diver is a reef ambassador, which is why we encourage all guests to become certified Green Fins divers.
A Glimmer of Hope Beneath the Surface
Despite the looming threat, there is hope. A passionate community of scientists, dive pros, citizen volunteers, and ocean advocates is working daily to restore and protect Villa Blanca Reef. From coral nursery maintenance to education and policy advocacy, we’re fighting for this reef — and we’re not alone.
Come dive Villa Blanca Reef. It might be your last chance, but we and others are working hard to ensure it will not get to that point. Book now to reserve your spot!
