Refresher Course: Casa Cenote & Dos Ojos
Refresh your diving skills in Tulum’s iconic cenotes with Mexidivers Tulum. Practice essential techniques while navigating the crystal-clear waters of Casa Cenote and the light-filled caverns of Dos Ojos.
Tulum’s Riviera Maya coastline is home to some of Mexico’s most captivating cenotes—natural freshwater sinkholes formed by collapsed limestone that connect to vast underwater cave systems. Situated on Carretera Tulúm-Boca Paila, km 5, near the Hotel Zamas hotel zone, Mexidivers Tulum offers a standout refresher diving course that plunges divers into two iconic cenotes: Casa Cenote and Dos Ojos. This 4.5-hour experience is designed for certified divers who haven’t been underwater in a year or logged fewer than 25 dives, providing a safe yet thrilling way to regain essential skills.
The course begins with an open-water dive in Casa Cenote, where shallow depths (max 8 meters) and crystal-clear waters welcome adventurers into a unique ecosystem. Here, freshwater mingles with seawater, supported by roots and mangroves visible above and below the surface, fostering vibrant aquatic life. The second dive takes place at Dos Ojos, one of the most famous cave systems in the area.
The course focuses on the “Barbie Line,” a cavern with expansive galleries and filtered sunlight that highlights stunning limestone formations. Maximum depth on this dive is 6 meters, making it ideal for skill practice while experiencing the otherworldly atmosphere of cavern diving. Mexidivers Tulum’s expert instructors guide every moment, ensuring divers relearn vital techniques like buoyancy control and mask clearing in a supportive environment.
Equipment rental and round-trip transportation are included, allowing guests to concentrate fully on the water. Entrance fees to the cenotes are paid separately at the sites. What makes this offering truly special is its setting: the intersection of jungle and sea within geological marvels that Titanically shaped the Yucatán Peninsula.
Mexidivers stands out in Tulum’s outdoor scene by combining technical dive refreshers with evocative, locally rich underwater environments. Whether rekindling a passion or shaking off rust, this trip is a prime gateway into the breathtaking natural wonders beneath the surface in Quintana Roo.
