Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.
The dive
You descend under a large overhang at a half-dry entrance. Inside are air domes with platforms (Heaven's Gate, Disneyland).
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, Casa Cenote (Manatí), Gran Cenote, Calimba (Kalimba), Dos Palmas, Otoch Ha (Nariz), La Concha, Ho-Tul / Cuzan Nah, Outland, Pedrín Fenómeno, Chun-Ya
Profile and sections
You descend under a large overhang at a half-dry entrance. Inside are air domes with platforms (Heaven's Gate, Disneyland). The Blue Abyss is about 3 km of swimming or scootering from Nohoch: with trimix and long deco it is an expert dive.
Nohoch Nah Chich means ‘big bird house’ in Maya. The system is about 67 km long and connected to Sac Actun; it is part of Sistema Sac Actun (Maya: ‘white cave’): 379.6 km surveyed, down to -119.2 m (QRSS, Jan 2025).
Practical: cave divers may dive here independently or guided; the entrance fee is not known. If you want to dive Outland, a cave further along the same jungle track, collect the key to its gate and the instructions here first.
- Depth and profile
- Mostly shallower than -15 m; Blue Abyss shaft about -35 m, deepest passages to about -72 m (ProTec reports deeper)
- Intro level
- Recreational cavern line (since Nov 2024) and shallow main lines.
- Configuration
- All configurations; Blue Abyss via Pet Cemetery sidemount only
- DPV: DPV-suitable
- Long ornate tunnels; the Blue Abyss is ~3 km in, a ~3 h scooter round trip ('DPV needed')
Who can dive where
- At least Cavern
- Cavern zone / easier part: at least Intro to cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 72 m (trimix or deco may be needed)
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.
