Most of the Klostersee is a free outdoor pool with showers, changing rooms, toilets and sunbathing areas. In the Seecafé you can sit, have a drink, eat a little something and watch the hustle and bustle.
The Antoni pond is also ideal for a break in an idyllic setting in winter. But then it's just frozen over - and the idea of dangling your legs in the water is probably only half as pleasant. 😜
