Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

An active resurgence in the Montsec de Rúbies, with visibility often only 1–2 m. An exploration cave, not a training dive. Biospeleologists visited it as early as 1910.

After rain an underground river flows through the whole gallery and the water rises sharply (S1B from -33 to -47 m, deepest point from -73 to -87 m). Dive only at low water.
Visibility often 1–2 m, sand banks almost up to the ceiling and collapsed zones: restrictions and line work in poor visibility.
Profile and sections

An active resurgence in the Montsec de Rúbies, with visibility often only 1–2 m. An exploration cave, not a training dive.

Biospeleologists visited it as early as 1910. Diving exploration has gone on since the 1970s, with major finds in 2012–2022 by Catalan clubs (incl. GEB Badalona and Otxola); in 2022 a push in a new branch stopped at -40 m.

Practical: the Pou del Naixement (1.5 m step down) needs a small ladder or steps.

Depth and profile
S1B to -33 m (-47 m at high water), side branch S1C 65 m · then dry galleries (Ferran Marqués 62 m, GEB 2012 214 m, Ibèrica 422 m) · Pou del Naixement → Nil gallery to -73 m (-87 m at high water) · 2,213 m surveyed, ~1,400 m underwater at high water
Configuration
Sidemount; low dry passages to carry through, sand and collapsed sections underwater (estimate)
DPV: Not DPV-suitable (estimate)
Dry carries, low passages and poor visibility

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

Next to the C-13 (km 70.870) in the Congost de Terradets, near a river bridge. Two entrances join after 37 m via a low passage; then ~80–200 m of dry gallery to the water, depending on the level. Everything has to be carried.
