About
Lake Thun, also known as the Thunersee, is an alpine lake that stretches between the town of Thun and Interlaken in the Bernese Oberland of Switzerland. It is an easy and pleasant place to spend an unhurried afternoon, whether you are passing through the region or building a visit around it.
What to expect
The lake is best appreciated from the water. Boat cruises run along its length, giving you a slow view of the shoreline and the surrounding slopes. The setting is the main draw: the lake sits beneath the Bernese Alps, and the mountain views change with the light and the weather, making each crossing feel different.
Because the lake lies between two towns, it works well as a day trip or as part of a longer journey through the area. Thun, at the western end, is the natural starting point for many visitors, while Interlaken at the other end offers further connections into the wider region.
Planning your visit
- The lake is open at all times, so you can visit whenever suits you.
- Boat cruises are the most rewarding way to see the lake and its mountain backdrop.
- Both Thun and Interlaken provide places to stay, eat and wait between sailings.
- Bring a light layer, as conditions on the water can feel cooler than on the shore.
For visitors who enjoy scenery, calm water and the feeling of being in the Alps without a demanding itinerary, Lake Thun is a straightforward and rewarding choice.
