Find a bench and relax on Grunderinseli, the island on Lake Thun

Take a winter walk to Grunderinseli or enjoy the view as you barbecue your food over the fire. Grunderinseli is a fantastic island on Lake Thun and a great place to visit at any time of year.

Grunderinseli lies approximately 50 m from the bank of Thun’s Lachen Quarter and is connected to the mainland by a wooden walkway. Cross the walkway and enjoy the fantastic view of the Eiger, Mönch and Jungfrau, as well as Oberhofen Castle on the opposite bank. Are you looking for the perfect spot for a barbecue?
