Lake Thun and Spiez

The bigger, gentler lake, ringed with castles and vineyards and backed by the snow peaks. The boat from Thun to Interlaken is the slow, right way to arrive in the Oberland.

Overview

A lake of castles

Lake Thun stretches from the medieval town of Thun to Interlaken, with the Niesen's pyramid and the Bernese Alps along its southern skyline.

Spiez castle stands on a promontory above its bay, with vineyards on the slope behind. Across the water, Oberhofen castle rises straight from the lake with a slender tower and gardens.

At the outflow of the Aare, Thun has its own castle above a medieval old town. On the Obere Hauptgasse, the pavements run on raised terraces above the shops.

Boats link them all, ending at Interlaken West: the slow, right way to arrive.
