About Brienzersee
The Brienzersee is about 14 km long and lies between steep mountains, which gives the water its green-blue color from glacier-fed rivers. Passenger boats have sailed it since 1839.
BLS boats depart from a quay on the Aare river next to Interlaken Ost and run to Brienz at the far end. Stops include Bönigen, Iseltwald on a small peninsula on the south shore, Giessbach at the foot of the waterfalls, and Ringgenberg and Oberried on the north shore.
The Lötschberg, a side-wheel steamship built in 1914, usually operates in the European summer. The rest of the fleet consists of motor vessels, some offering breakfast and sunset departures.
The season typically runs from April to early December, with more services from June to September. In winter, from December to March, Brienzersee boats do not run regular services.
Before you go
Practical information
Cidade Turismo reviews its information regularly, but something may have changed. Check with the place before planning your trip.
How much time to set aside
From one and a half hours (just the crossing) to a full day, with stops.
Best time
From June to September, when there are more departures and the Lötschberg steamship typically sails. In sunshine the water's colour becomes more intense.
How to get there
The quay is behind Interlaken Ost, a few steps from the train platforms. In Brienz the quay is opposite the station.
Tip
Iseltwald is very busy at the quay; arrive early if you want to walk the peninsula at a relaxed pace. For the Giessbachfälle, get off at Giessbach See and go up by funicular.
