Walensee

The Walensee or Lake Walen is less than an hour southeast of Zurich. During spring and summer you can go hiking, especially along the north shore of the lake. Between Weesen to the west and Walenstadt to the east, there are areas for BBQs, swimming or just relaxing looking at the landscape. An hour's walk from Weesen is the waterfall Seerenbach, 305 m, the highest in Switzerland. It's worth the trip.
