Every summer, thousands of people gather on the shores of Lake Zurich for one of the city’s most iconic traditions: swimming straight across it.
Around 9,000 participants enter the water together and follow a marked 1.5‑kilometre route from one side of the lake to the other. It is not a race. There are no medals. Just a shared experience that turns the lake into a moving line of swimmers stretching across the horizon.
The atmosphere starts long before the first strokes. Groups meet in the park, swimmers prepare along the shoreline, and boats wait along the route to guide everyone safely across.
Then, slowly, the entire crowd moves into the water.
Reaching the opposite side feels less like finishing an event and more like taking part in something that belongs to the city itself. Simple, local, and surprisingly memorable — especially on a clear summer day in Zurich.
