Exploring Casetas: Isla Mujeres’ Rediscovered Shipwreck

At Pocna Dive Center, we love uncovering forgotten corners of the sea. Every so often, our team sets out on exploratory dives to revisit sites that rarely see bubbles, and sometimes we discover something worth sharing with our divers. That’s exactly how Casetas became our newest addition to the wreck dives of Isla Mujeres.

The Story Behind Casetas

Casetas is part of the Chairel, a car ferry deliberately sunk in the year 2000 to create an artificial reef. What should have been a straightforward sinking didn’t quite go as planned. The ferry encountered weather issues during its descent, capsized, and landed upside down on the seabed.

Nature added another twist five years later. In 2005, Hurricane Wilma tore through the Mexican Caribbean and split the ferry horizontally, scattering its remains. The top and bottom sections were carried apart by 2.5 km (about 1.5 miles), creating two separate wreck sites.

For years, Pocna Dive Center has been taking divers to the lower portion of the Chairel, a popular artificial reef teeming with life. But it wasn’t until September 2025 that our dive team officially opened the upper wreck site—Casetas—to our divers.

Diving Casetas

Casetas rests at 24 meters (79 feet), making it ideal for experienced divers who are comfortable with deeper waters and drift diving conditions. Currents can be strong in this area, adding an extra element of adventure to the dive.

The wreck is broken into several pieces: a large section that allows light to penetrate and smaller fragments scattered nearby. Because Casetas has seen very little diver traffic over the years, it feels almost untouched. Schools of reef fish, curious barracudas, and other marine life make this site vibrant and full of surprises.

With careful planning and guidance from our team, Casetas offers a safe yet thrilling experience for those with the right level of experience.

By adding Casetas to our dive roster, Isla Mujeres now offers divers an even greater number of shipwrecks to explore, each with its own history, marine life, and underwater adventure. Combined with our other wrecks—including the Chairel lower section and sites featured in our shipwreck guide—Casetas helps make Isla Mujeres a premier destination for wreck diving enthusiasts.
