Thun

Recommended stay: 1 day
Getting around: Thun's old town, notable for its rooftop-level walkway along Hauptgasse (shops are entered from a raised terrace above the street, with the street itself below), is compact and walkable. It sits on the main rail line to Bern (about 20 minutes) and Interlaken (about 20 minutes), and CGN-style boats on Lake Thun connect it to lakeside villages and Interlaken as a scenic alternative to the train.
Hours: The castle museum (Schlossmuseum Thun) has seasonal hours, generally shorter in winter with some weekday closures; lake boats run roughly April to October and are reduced or suspended in winter.

Thun sits where the Aare river flows out of Lake Thun, with a medieval castle (Schloss Thun) on a hill overlooking the old town and, on clear days, the Bernese Alps rising beyond the lake. The town's most distinctive quirk is its main shopping street, Obere Hauptgasse, where the roofs of the ground-floor shops form a raised pedestrian terrace at first-floor level — you can walk along the rooftops of one row of buildings, a layout that's unusual even by Swiss old-town standards.

Thun functions as the gateway to Lake Thun, and the lake boats connecting it to villages like Spiez and on to Interlaken are one of the more relaxed, scenic ways to see the region's alpine backdrop without a car. It's typically a half-day stop — old town, castle, a walk along the river — either on its own or paired with a boat trip up the lake toward Interlaken.
