[Switzerland] Recommended city Thun

I went to Thun in Switzerland. Thun is located west of Interlaken, and it takes about 1 hour and 20 minutes by express train from Zurich. From Bern, it takes about 18 minutes by express train. There is a large lake called Lake Thun, and many people swim in the lake in the summer. In addition to the lake, there is also Thun Castle, a castle built in the 12th century. Compared to Zurich and Bern, there are fewer people, so I think it is an easy city to visit. When we had a picnic near Lake Thun, swans and many other water birds came. It is very easy to access from the capital Bern by express train, so I recommend it. #Spring0yenTrip
