It offers views of green meadows, forests, the typical alps as well as the eternally white peaks of the Eiger, Mönch and Jungfrau beyond. During the summer months and between Christmas and New Year, the steamship Blümlisalp clatters and puffs its way across the clear blue waters of Lake Thun in the middle of this landscape. Your trip on Lake Thus can start at any jetty round Lake Thun. Select the boat trip on Lake Thun that most appeals in terms of departure time or itinerary. Trips leave from Interlaken West and proceed along the Neuhaus nature reserve, on towards the St. Beatus Caves and Beatenbucht, to Spiez, Gunten, Oberhofen, Hilterfingen, Hünibach and then ultimately on to Thun. The entire trip from Interlaken to Thun takes around two hours and 10 minutes.
