Tulum Diving Center is a specialist operation focused on the unique underwater topography of the Yucatan. Based at the Hotel Casa Cenote, just ten minutes from the centre of Tulum, the centre has joined forces with Manati Divers to provide a dedicated hub for cavern and cave exploration.
The centre is defined by its focus on technical progression. While it welcomes all levels of divers, its core identity lies in its expertise in overhead environments, offering a structured path for those wanting to move beyond the reef and into the cenote systems.
The centre is led by Cathy Sytsma and Craig Gillespie, two Silver Course Director instructors with more than 75 years of combined experience. This level of expertise ensures that training is handled with a high degree of technical precision and safety.
Instruction is tailored to the individual or small groups, with a focus on private or semi-private sessions. For TDI specialty courses, the instructor-to-diver ratio is kept to a maximum of three divers per guide. The team operates in English and utilises PADI's digital learning platforms, allowing you to complete your theory work at home before arriving on site.
With two instructors on staff, the centre maintains a professional atmosphere dedicated to high-quality training standards. They manage all aspects of the student experience, from initial certification to advanced technical specialties.
The centre provides a comprehensive range of PADI certifications, starting from Discover Scuba Diving and Open Water Diver through to Advanced Open Water and Rescue Diver. For those looking to professionalise their skills, they offer Divemaster and Assistant Instructor courses.
Specialised training is a core component of the curriculum, with specific focus on Sidemount and cavern diving. The centre also offers technical training through TDI specialties, specifically designed for those navigating the complex cave systems of the region.
Dos Ojos is a world-renowned cenote system. While the illuminated areas are popular for snorkeling, the underwater sections offer incredible opportunities for cavern and cave diving through intricate formations.
The Caribbean Reefs provide a different environment, consisting of shallow reefs and coral gardens. These sites are accessible from the Open Water Diver level and offer a gentler introduction to the local marine life.
And some of the dive sites the centre runs.
The cenote and reef environments host a variety of species. You will frequently encounter Green sea turtle (Chelonia mydas) and various tropical fish species moving through the water columns. In the shallower reef areas, snapper schools and juvenile reef fish are common sights.
In the more complex environments, keep an eye out for cave-adapted crustaceans and freshwater crabs. These smaller inhabitants are a key part of the delicate ecosystem within the underground river systems.
Throughout the area, you may also spot larger pelagic visitors such as Barracuda (Sphyraena) or Tarpon (Megalops) passing through the coastal waters.
