Option Lake Cruise on Lake Thun
If you have good weather and you would like to take a lake cruiser, you could get off the train in Spiez. From the Spiez train station, it is about a 10 minutes "sign-posted" walk down to the landing, from where you could take a boat to Interlaken West. There are also a few restaurants right at the landing, if you did not have lunch yet or would like to sit down for coffee. Upon arrival in Interlaken West you would have to take a train or bus to Interlaken Ost (or walk for approx. 20 minutes along Höhenweg).

> The boat which would combine with your itinerary leaves from Spiez at 12:28, 13:28 and 14:28. The one at 13:28 presumably being a historic paddle wheel steamer.
