History:
Originally the USS Harlequin, this World War II-era minesweeper was intentionally sunk by the Mexican Navy in the 1980s to create an artificial reef. It was later split into two large sections by Hurricane Wilma in 2005. The stern offers fantastic penetration opportunities for certified divers. You’ll even find a bathroom still intact! From December to March, this site becomes a haven for spotted eagle rays, sometimes in the dozens. This is the most iconic wreck around Isla and a must for experienced divers.

History:
The sister ship to the famed C-58, the C-55 is a former minesweeper turned artificial reef. It now rests off the coast of Isla Mujeres. Though more compact in layout, it delivers an equally thrilling dive experience, especially for those who can handle its famously strong currents. Over time, storms have reduced it to smaller, scattered pieces, giving it a more chaotic and haunting appearance. From eagle rays gliding through the blue, to moray eels hiding in crevices, this site is bursting with underwater drama. When the season is right, eagle rays return in numbers. This makes it a highlight for advanced divers seeking that classic deep wreck vibe with a dose of wild beauty.

History:
The Chairel was once a familiar sight above the waves. It operated as a car ferry between Isla Mujeres and Cancun in the late 1980s. After years of faithful service, her journey didn’t end on land. She was intentionally sunk in 2000 to create an artificial reef. Now lying upside down, the Chairel has transformed into an eerie yet inviting dive site. Broad swim-throughs and shadowy corridors now teem with a diverse array of marine life.

Casetas is part of the Chairel ferry, which met a more dramatic fate after its sinking. Initially resting intact on the seabed in 2000, the wreck was later split horizontally by Hurricane Wilma in 2005, separating the top and bottom sections by 2.5 km (1.5 miles). The upper portion, now known as Casetas, has remained largely untouched by divers, offering wide-open swim-throughs and scattered debris that provide shelter for a vibrant variety of marine life.

History:
The Ultrafreeze was once a large, hardworking freezer cargo ship. It transported goods through the Caribbean. In the 1970s, a catastrophic onboard fire led to the deliberate sinking of the vessel to create an artificial reef. Today, her broken and scattered remains create an underwater maze that adventurous divers can explore. Twisted metal, towering hull sections, and thick marine growth make the Ultrafreeze one of the most dramatic and hauntingly beautiful wreck dives in the area.

6. Hondureño
History:
Once a hardworking shrimp boat, the Hondureño flew under the Honduran flag. It met its fate during the devastating Hurricane Gilbert in 1988. Powerful winds and raging seas forced her beneath the waves. She now rests upright on the seabed. Over time, the ocean claimed her, offering shelter to marine life like moray eels, snappers, amberjacks, and nurse sharks.
