The dive

Part of Sistema Sac Actun. Also in this system: Dos Ojos, The Pit (El Pit), Taak Bi Ha, Nicte-Ha, Pet Cemetery (Cenotes Sac Actún), Dreamgate, Nohoch Nah Chich, Casa Cenote (Manatí), Gran Cenote, Dos Palmas, Otoch Ha (Nariz), La Concha, Ho-Tul / Cuzan Nah, Outland, Pedrín Fenómeno, Chun-Ya

Profile and sections
Calimba is part of Sac Actun (Gran Cenote / Ho-Tul). With maze sections (Much's Maze), many jumps and long distances, navigation is complex; off the Gran Cenote line there is a jump to Bosh Chen, a cenote with a skylight. Not suited for your first cave dive here.
Sistema Sac Actun (Maya: ‘white cave’) has 379.6 km surveyed, down to -119.2 m (QRSS, Jan 2025).
Practical: it has become a lot pricier in recent years (opencaves.info). A traverse to Gran Cenote is possible, but that one is closed to divers.
- Depth and profile
- Shallow (exact depth unknown)
- Configuration
- Sidemount recommended; stages are common
- DPV: Not DPV-suitable (estimate)
- Small, maze-like cave (Much's Maze, Boa restriction, many jumps); sidemount and stages rather than a scooter
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Experienced divers only
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.
