Profile and sections
The water is 10–11 °C. Visibility gets poor towards the end of the main gallery.
According to GAEM this is the largest sump in central Spain. GAEM (Madrid) has explored it since 1995 with other clubs; in 2023 the Piedruca gallery connected the sumps.
Practical: the spring lies at an altitude of ~1,205 m, so set your computer for it.

- Configuration
- Sidemount recommended: the passage starts at ~1.7 × 1.2 m; backmount is tight (estimate)
- DPV: Not DPV-suitable (estimate)
- Tight passage (~1.7 × 1.2 m) and poor visibility further in; little gain

- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 44 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.
How to get there
Small opening ~10 m behind the spring outlet, on the left bank of the Tajo in the Parque Natural del Alto Tajo, at ~1,205 m altitude. Groups of more than 3 and exploration need authorisation from the Delegación Provincial (Guadalajara); scuba diving has its own rule in the park plan — request permission in advance.
