Posted by Lake Brienz is one of the two large alpine lakes in the Bernese Oberland and lies east of Interlaken. Together with Lake Thun, it shapes the landscape of this well-known Swiss holiday region. Lake Brienz is slightly smaller than Lake Thun, but deeper and visually more dramatic due to the steep mountain slopes and waterfalls that reach directly down to the shore.
The lake is famous for its intense turquoise color, which is caused by fine rock particles carried into the water by mountain streams and glaciers. The surrounding alpine environment, with its rich flora and diverse fauna, makes the area especially attractive for nature lovers.
Location and geography
Lake Brienz is located in the heart of the Swiss Alps and is surrounded by some of the most famous peaks of the Bernese Oberland. South of the lake rise mountains such as Eiger, Mönch and the Jungfrau, all exceeding 4,000 meters. This alpine setting strongly influences the climate and outdoor opportunities around the lake.
The lake is around 14 kilometers long and just under three kilometers wide, with a surface area of about 30 square kilometers. Its maximum depth of roughly 260 meters makes it deeper than nearby Lake Thun. A full drive around the lake by car covers approximately 40 kilometers.
Lake Brienz and Lake Thun are only about two kilometers apart. Between them lies Interlaken, the main transport hub of the region. The River Aare flows out of Lake Brienz, through Interlaken, and into Lake Thun, naturally connecting both lakes.
