Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.
The dive
The water is ~9 °C, the air 12 °C. Visibility and flow vary with rain, as in the Veci.
Profile and sections
The water is ~9 °C, the air 12 °C. Visibility and flow vary with rain, as in the Veci.
This is Oliero's main cave, explored in 1822 by Alberto Parolini and a show cave since 1832 (~30 min boat tour, a hall with a 14 m high flowstone 'waterfall').
Practical: local centres ask for a higher certification here than for the Veci.
- Depth and profile
- Show-cave lake to -13 m (Wikipedia). Dive section: deepest point -63 m at 870 m (1989), further in back to -12 to -20 m; connected to the Veci.
- Configuration
- Low: at the lowest points just over half a metre high. Sidemount is the obvious choice; backmount only if you can stay very low and streamlined (estimate). Water ~9 °C.
- DPV: Not DPV-suitable (estimate)
- Low passages: a scooter makes little sense here (estimate).
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 63 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
Inside the Parco Grotte di Oliero; booked through the same system as the Veci (Ivan Team, online, at least 3 days ahead, €10 per diver). The Siori is also the show cave: in season visitors go in by boat as far as the inner jetty.
