The dive
The Bätterich is a karst spring in Lake Thun and the outlet of the Siebenhengste-Hohgant system (catchment ~40 km²). Stirred-up sediment can strongly reduce visibility.
Profile and sections
The Bätterich is a karst spring in Lake Thun and the outlet of the Siebenhengste-Hohgant system (catchment ~40 km²). Stirred-up sediment can strongly reduce visibility.
The first dives were in 1969 (to -60 m). In 2007 a collapse zone at -31 m was passed, with a dry continuation beyond. The spring is also dived by teams from abroad.
Practical: the best period is winter and late summer.
- Depth and profile
- Entrance in a funnel at ~-12 m (-21 m according to one source) · then down to ~-45 m, middle section around -20 m, deep section to -79.9 m (2007) · restriction at -68 m · length >300 m
- Configuration
- Backmount (double 20 l with stages) and CCR have been used here. Water 6–8 °C: drysuit; teams use heating. Trimix and deco needed for the deep section.
- DPV: DPV possible (estimate)
- Explorers used scooters (2010: one was left at the restriction at -68 m); for a cave of a few hundred metres the gain is limited.
Who can dive where
- At least Full cave
- Configurations: Backmount / twinset / Sidemount / CCR / Small cylinders / no-mount (speleo sumps)
- Goes down to 80 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
Park at Sundlauenen on the north shore of Lake Thun. From the car park, swim ~200 m east along the shore and descend at the first boathouse; a funnel in the lake bed leads to the entrance.
