The dive
This is an expedition/speleo dive, not a regular cave dive.
Profile and sections
This is an expedition/speleo dive, not a regular cave dive. Sa Oche is a temporary spring and the overflow of the Su Bentu–Su Gologone system: after heavy rain a lot of water pours out and the cave 'roars' (together called 'the voice of the wind'). The sump connects to Su Bentu, a large system with an underground river.
The cave was surveyed in 1980 (R. Loru, L. Fancello, D. Vacca, Gruppo Grotte Nuorese). In October 2019 the CNSAS cave rescue trained the rescue of two injured cave divers in the connecting sump here.
- Depth and profile
- Cave ~400 m with three lakes; the terminal sump to Su Bentu is >100 m long. The cadastre gives -64 m of relief; the depth of the sump itself is not known.
- Configuration
- Sidemount or small cylinders: you carry your gear through the cave and past the lakes.
- DPV: Not DPV-suitable (estimate)
- Short sump after a gear carry: no scooter.
Who can dive where
- At least Full cave
- Configurations: Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- 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
Valle di Lanaittu (Oliena): park at the 'Rifugio', then the footpath (same start as the nuraghic village Sa Sedda 'e sos Carros). Paid entry. Wide entrance with three lakes; the terminal sump lies beyond them.
