About This Swimming Area
Lake Brienz, east of Interlaken in the Bernese Oberland, features stunning aquamarine hues from glacial silt, perfect for swims near Iseltwald's pebble beaches. Hike 10 minutes from the boat dock (bus from Interlaken Ost) to secluded coves with Giessbach Falls views. Depths plummet quickly, but surface swims stay shallow. Temps: 18-23°C (64-73°F). Ideal for intermediate swimmers seeking tranquility away from crowds. Check Lake Brienz navigation schedules to avoid barge paths. Practice Leave No Trace by using provided bins.
Safety Considerations
Cleaner than most lakes, Brienz still harbors risks: steep drop-offs 20m offshore cause panic dives, per local rescue logs. Minimal currents, but katabatic winds whip up 1m waves. Boats from Giessbach ferry demand visibility. Glacial cold layers induce shock; enter feet-first. No lifeguards, so buddy system essential. Avoid evenings when visibility drops. Stats: fewer incidents than Aare, but tourists underestimate depths. Use Swiss Flood Reporter app for levels post-rain.
Essential Gear
REI Co-op swim buoy, rock-pro shoes like Chacos, thermal rash guard, dry bag for clothes, headlamp for late swims, first-aid kit with cramps relief.
Emergency Tips
