Lake Thun is one of the most beautiful in Switzerland. You can travel either from Interlaken or from Thun town. Thun is equidistant from Zurich and Geneva by train. We took a boat trip in the lake from Interlaken. The one hour ride takes you amidst the beauty of the lake and it's beautiful shore. You find number of waterfalls and picturesque villages around the lake. The green water of the lake , blue sky above and snowcapped Alpine mountain around the lake makes the entire trip very enjoyable.
