Kilchberg badi is located about 20 minutes by train or car from central Zurich on the Zurichsee. It also happens to be right next to the Lindt & Sprungli factory so provides a feast for the senses as you enjoy the cool, clear waters of the lake while wafted with the fresh chocolate smell. There's a large grassy area to spread out on (note: plastic-backed picnic rugs are not allowed) and lake access is via steps, a waterslide or from a rocky "beach" area. If the lake is too chilly, there's a man-made outdoor pool that's heated to the temperature of the cholcolate factory, 22°C to 26°C. Food is provided by Hiltl and is the usual delicious vegetarian buffet. And there's a nice kids area with a paddling pool and play equiment. On warm summer weekends this place is mobbed with families and the small carpark fills up fast, so it's worth arriving early to stake out a spot.
