Intro to Cave in Tulum: 15 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 6 publish course prices.
TecDiveTools lists 15 dive centres teaching Intro to Cave in Tulum, Mexico. 6 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). 14 of these 15 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, 10 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
First formal cave certification beyond Cavern, introducing basic cave navigation and single-line-following technique with conservative penetration limits before progressing to Full Cave. Teaches jump-free single-line navigation, silt-avoidance finning, and team communication specific to cave environments, without yet allowing the complex multi-line navigation Full Cave covers. Deliberately designed as a bridge course—TDI limits penetration distance and duration here specifically so divers build cave comfort in stages rather than jumping directly to unrestricted cave access.
Divers must perform jump-free single-line navigation, demonstrate silt-control finning, maintain team communication and awareness, complete 4 dives with limited penetration (no fixed depth, limited by gas and distance), accumulate 80 minutes of bottom time minimum across 2 different cave locations, and execute emergency procedures safely.
The centres listed above teach TDI Intro to Cave in Tulum, 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.
15 dive centres on TecDiveTools teach TDI Intro to Cave in Tulum, Mexico. 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.
