Profile and sections
In Otoch Ha you reach a T right away, at about -8 m. To the right runs about 600 m of passage, to the left about 520 m of decorated rooms with jumps and pinched sections to Cenote Aktun Hu (bat cave, with its own surface). The cave is nicely decorated but very silty, and the line can be hard to see. It is an 'all-time favourite' per opencaves.info.
Otoch Ha lies behind Rancho San Felipe and is part of the Aktun Hu/Nohoch area, part of Sistema Sac Actun (Maya: ‘white cave’): 379.6 km surveyed, down to -119.2 m (QRSS, Jan 2025).
Practical: fee unknown.
- Depth and profile
- Mostly -8 to -10 m, max about -13/-14 m
- Configuration
- Sidemount recommended: tight, awkward entry in backmount; otherwise roomy enough for scooters
- DPV: DPV-suitable
- Long E tunnel suits scooter + stage dives (documented); pinched, decorated rooms toward Aktun Hu and a very silty entry need care
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 14 m (trimix or deco may be needed)
- 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.
