This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.
How to get there
About 4.5 km south-west of Tulum, just past the turn-offs to Dos Pisos and Monkey Dust. There is no key at ProTec any more: the cenote has a new owner, who has not (yet) made an arrangement with them. Diving only with the owner's permission; ask locally beforehand (e.g. at a dive centre in Tulum) whether and how that is possible now, and don't just turn up. Parking, tables, toilets; wooden ladder and platform. Fee unknown.
