About This Route
Lake Brienz, sibling to Thun, offers advanced SUP challenges with its 12-kilometer length and Giessbach Falls-fed waters in the Bernese Oberland. Route: Downwind run from Brienz village to Iseltwald, navigating 200-meter cliffs and alpine torrents. Deeper and windier than Thun at 558 meters elevation, it's for experienced paddlers facing consistent westerlies. Comply with federal shipping regs; SUPs must carry ID lights after dusk.
Safety Considerations
Fierce föhn-like gusts up to 40 knots barrel down from Brünig Pass; only paddle with pro forecasts from MeteoSwiss. Torrent inflows from Lombach and Aare create deadly whirlpools; scout from shore first. Timber logs from logging float unpredictably; evade actively. Water at 7-14°C demands drysuits. High boat density from sightseeing cruises requires right-of-way rules. Clean meticulously for quagga mussels, per canton mandates. Leash critical in surfable swells; practice eskimo rolls if touring.
Essential Gear
Advanced setup: Mustang Survival drysuit, Jimmy Styks leash, Starboard Generation LT SUP, Epic V5 paddle, throw rope, helmet, flare kit, and Garmin inReach.
