Are you ready for the ultimate swimming adventure? On August 16, 2020, we swim from Lake Walensee to Lake Zurich. We manage the 18 km long route through the Linth Channel in a group under the guidance of experienced swimming coaches. If you are able to swim in the standing water about 4 kilometers nonstop (crawl), you are ready for this challenge. Sections can also be covered on foot.

The Linth canal swimming is unfortunately fully booked. We have a waiting list, but we cannot guarantee participation. We ask for your understanding that we cannot expand the group size infinitely for safety reasons.


We swim together from Weesen to Schmerikon. The distance is 18 kilometers (about 17 kilometers in the channel and 1 kilometer in the lake). This corresponds to about 7 to 9 kilometers (depending on the current) in the standing water. The Linth Channel is swimmable throughout. A special experience are the rapids at Ziegelbr├╝cke. It can be disembarked there and also otherwise time and again and partly distances can be covered on foot (continuous dam path) or on the SUP*. A total of four joint stops are planned, including a food stop. You should be able to swim about 4 kilometers (crawl) in the standing water. The water temperature is much cooler than in Lake Zurich. Wearing a neoprene is therefore mandatory, it is recommended to carry a swimming buoy (neoprene can be rented with advance booking and fee at Tempo Sport).
