Emergencias
- 112, or Rega 1414 (say 'Tauchunfall', diving accident). For a cave accident, Spéléo-Secours Suisse, which has its own cave-diving rescue team, is alerted through Rega. DAN Europe: +39 06 4211 5685.
- Hyperbaric chambers (GTÜM list, Jan 2025): HUG Geneva, Rue Gabrielle-Perret-Gentil 4, 1211 Genève 14, 24/7, +41 22 372 22 44 · HBO-Zentrum Basel, Kleinhünigerstrasse 177, 4057 Basel, +41 61 631 30 13 (30 min advance notice) · mobile emergency chamber in Mendrisio (close to the Sorgente Bossi), 24/7, +41 91 800 18 32. Rega decides where you go (2009 arrangement: German-speaking Switzerland to chambers in Germany, Romandy to Geneva, Ticino to Italy).
Acceso y normas
- Access differs per site. Sorgente Bossi (Arogno, TI): only after online registration and approval by Underwater Training CMAS.CH, which the municipality put in charge of access (Full Cave minimum, dive medical, search-and-recovery insurance, booking and key pick-up; regulations of 3 December 2024). Lac souterrain de Saint-Léonard: show cave, not open to divers. Bätterich, Gelber Brunnen and Rinquelle: no permit or ban known; the Rinquelle cave may only be entered by cave divers.
- Drinking water: many Swiss karst springs are captured for drinking water. In groundwater protection zone S1 around a capture, only installations and activities that directly serve the drinking-water supply are allowed (BAFU) — so no diving there. Ask the canton or municipality beforehand about any spring not listed here.
Gases y carga
- Gas: Lake Thun: Dive Center Thunersee in Hilterfingen (trimix and O₂ per its SSI listing; outdoor station air or nitrox 36% to 200 bar). Eastern Switzerland: Tiefenstein in Horn on Lake Constance (trimix 18/45, O₂, helium, 24 h stations) and Divepad in Urdorf near Zürich (trimix, O₂, helium, 24/7 with an app subscription). Ticino: ask about fills when booking the Sorgente Bossi; compressors at the spring are banned. Western Switzerland: DiveStation (Neuchâtel) and plongee.ch (Puidoux), see the Doubs and Jura region.
Agua y temporada
- Season and water: cold (Bätterich 6–8 °C, Rinquelle 6 °C, Saint-Léonard 11 °C): drysuit and heating. Bätterich best in winter and late summer (dangerous currents during spring snowmelt); Rinquelle practically only in winter at low flow; the Sorgente Bossi reacts slowly to rain and can be dived almost all year.
Día de descanso
- Non-diving days: the Beatushöhlen show cave at Sundlauenen, close to the Bätterich (~1 km lit); a boat tour on the Lac souterrain de Saint-Léonard (2026: 19 March–1 November, 10–17 h, online booking); the walk to the Seerenbach falls and the Rinquelle from Betlis (by car or boat via Weesen).
