Cave Decompression in Mexico: 12 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 9 publish course prices.
TecDiveTools lists 12 dive centres teaching Cave Decompression in Mexico. 9 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 10 of these 12 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 9 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

About the course
Combines cave diving with staged decompression, running mandatory decompression obligations while navigating a cave system. Teaches gas planning, stage management, and contingency thinking when both cave overhead constraints and decompression stops limit ascent simultaneously. For cave divers with decompression experience seeking to combine both skills.
Combines Full Cave and Decompression Procedures course standards. Requirements: cave navigation skills at depth, mandatory stop execution while managing cave environment, stage cylinder management in overhead, emergency procedures with limited ascent options, multi-level decompression gas switching
The centres listed above teach TDI Cave Decompression in Mexico. Requirements are set by the agency, not the centre, so they are the same wherever you train — what differs is price, class size and how much diving is included.
12 dive centres on TecDiveTools teach TDI Cave Decompression in Mexico: Playa del Carmen (8), Tulum (2), Akumal (1) and Puerto Aventuras (1). Each is listed above.
The cenotes are the benchmark place to train: around 24–25°C, very clear, with daylight cavern zones for a first course and some of the longest mapped cave systems in the world for full cave and beyond. The number of entrances and the variety of passage — decorated, wide, low, haloclined — let you train on different cave profiles in a single trip.
One centre in the TecDiveTools directory publishes a whole-course price for TDI Cave Decompression in Mexico: Deep Dark Diving, at $1,100. 2 centres charge by the day instead, which is not comparable with a course total. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
Between 4 and 6 days, based on the durations 3 centres publish for it in Mexico. The time depends on the centre's schedule, weather, and how quickly the required skills are demonstrated — agencies set a minimum number of dives, not a fixed number of days.
At the same tier in TecDiveTools' cross-agency comparison, dive centres in Mexico also teach IANTD Technical Cave Diver (29), NSS-CDS Tech Nitrox and Cave Decompression Diver (2) and PSAI Cave Decompression Diver (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
