About This Route
Lake Silvaplana at 1,821 meters in Engadin Valley exemplifies high-altitude diving, with ultra-clear waters revealing rocky bottoms and icebergs in spring near Silvaplana village. Depths to 72 meters host vendace fish; sites include Corvatsch drop-off. Access via Engadin Airport boats or shore at Chantarella. Extreme altitude mandates PADI Altitude Diver certification; DAN Europe altitude tables critical for DCS prevention.
Safety Considerations
Low barometric pressure increases decompression stops 20-50%; computers must compensate. Icy waters (4-14°C) heighten hypothermia; drysuits only. Windsurfing traffic requires SMB. Rapid weather from Maloja Pass; dive windows short. Follow Swiss Alpine Club guidelines for high-altitude ops.
Essential Gear
Extreme drysuit (Santi), Shearwater Perdix 2 Ti altitude computer, heated undergarment, extra thermal layers, emergency beacon.
Emergency Tips
High-alt DCS aggressive; immediate descent to lake level, oxygen, heli-evac 144 to St. Moritz then Zurich chamber.
Conquer Engadin highs safely with expert prep.
