Thun; the town where Lake Tunn and the Aare River are in the Interlaken region; the tourist is called a town because Switzerland is not big and because it looks like a town; it is actually the 10th city in Switzerland. The town of Tunn is not really a place on Lake Tunn, but it is named after Lake Tunn; 20 minutes from Bern to this train, 40 minutes from Interlaken; It is separated from Interlaken on the edge of Lake Tuen, so you can ferry here from Interlaken, and the scenery along the lake town described in previous notes can capture one or two. Tuen Castle is an iconic building, the one in Figure 1; Overlooking the city, you can climb the castle or take the Ferris wheel;
