The lake of Thun is a mountain lake fed by water flowing down from the partly icy heights of the area. That is why it is also a rather cold lake. Even at the highest point of summer it reaches a maximum of about 22°C. However swimming out in this lake in the midst of a majestic mountain scenery is a most thrilling experience….
The lake is on an altitude of 558m. The Aare river meanders on flowing through Bern that lies another 20km down the river. In summer many people float down the river on rubber boats.
A great way to explore the lake is via boat. There are five different boats that crisscross the lake according to a set schedule stopping at the major villages on both sides of the lake.
In Interlaken it is easy to stroll across to the port for boarding a boat cruising the lake on the other side of Interlaken, called the lake of Brienz.
