Switzerland · Lake Thun

Lake Thun (German: Thunersee) is an Alpine lake in the Bernese Oberland in href=”” target=”_blank”>Switzerland named after the city of Thun, on its northern shore.

The lake was created after the last glacial period. After the 10th century, it split from Lake Brienz, before which the two lakes were combined, as Wendelsee (“Lake Wendel”). The culminating point of the lake’s drainage basin is the Finsteraarhorn at 4274 meters above sea level.

Lake Thun’s approximate 2500 km² catchment area frequently causes local flooding after heavy rainfalls. This occurs because the river Aare (German: Aare), which drains Lake Thun, has only limited capacity to handle the excess runoff. The lake is fed by water from Lake Brienz to the southeast, which is 6 metres higher than Lake Thun, and various streams in the Oberland, including the Kander.

Following World War II and up until 1964, the Swiss Government disposed of unused munitions into Lake Thun. The quantity of munitions dumped is reported to be from 3,000 to more than 9,020 tons.

Lake Thun is surrounded by a fabulous mountain scenery, a myriad of cozy villages, and the charming cities of Thun and Interlaken. There you can enjoy wonderful views of the imposing mountain landscape or historic castles and romantic lakeside spots, and combine the trip with a fine dining on board.

Lake boats sail Lake Thun all year round. In summer a magnificently restored historic paddle steamer plies the lake. On the sunny southern slopes between Thun und Merligen subtropical vegetation flourishes that has given the region the name the “Riviera of Lake Thun”. On the opposite side of the lake, in the Bay of Spiez, which is presided over by a beautiful castle, you will find small vineyards. Not to be missed are the twelve one-thousand-year-old Romanesque churches that dot the coastline, for example in Einigen.

The small town of Thun at the western end of the lake with the same name is the gateway to the Bernese Oberland. It boasts a medieval Old Town, a mighty castle and an attractive pedestrian zone. One of the best-known towns in the Bernese Oberland is Interlaken, at the foot of the Jungfrau Region. The town at the upper end of Lake Thun is an ideal starting point for excursions to the Bernese Oberland.
