Profile and sections
The line starts above water. After the tight entry you reach a T: right goes to Dos Pisos Norte, left about 2 km to Monkey Dust. The floor ranges from fine brown silt to black organic 'mung', with white formations. Really there is only one dive to do.
Dos Pisos (Spanish/Maya: ‘two floors’) is a system of five cenotes (Balam, Dos Pisos Norte, Dos Pisos, Monkey Dust, Zooz), about 14 km. Sistema Dos Pisos: 14.8 km surveyed, down to -24.4 m (QRSS, Jan 2025).
- Depth and profile
- Average about -6 m, max about -24 m
- Configuration
- First ~60 m small and silty: sidemount most comfortable; roomier after that
- DPV: DPV possible
- DPV dives are done here, but the first ~60 m is small and silty before the cave opens up
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 24 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.
