Flussbad Oberer Letten

The Flussbad Oberer Letten is a free riverside swimming and sunbathing spot on the Limmat near Zürich Hardbrücke, in the Zürich-West district of Switzerland. Built on a former weir structure, the site consists of broad concrete and timber platforms, a small kiosk and grassy banks that lead directly into the fast, clear river. In summer it is among the most social places in the city, with swimmers, sunbathers, picnickers and volleyball players sharing the shore. Swimmers enter the river and drift downstream with the current, then climb out at marked exit points and walk back along the bank. The current can be strong and the water cold even in July, so the experience is better suited to confident swimmers. The bath is within walking distance of Hardbrücke station and the nearby Viadukt arches, which house shops, cafés and market halls, making it easy to combine a swim with lunch. Visitors typically spend two to four hours here, and the best time to arrive is late morning on a warm weekday. Weekends in July and August are crowded, especially after 14:00, and space on the platforms fills quickly. Photographers favour the view back toward the railway viaduct and the river bend from the downstream bank. Entry is free, and facilities are basic: changing areas, toilets and a seasonal kiosk offering drinks and snacks. There is no lifeguard guarantee throughout the day, so visitors swim at their own risk, and heavy rain upstream can make the Limmat unsafe. Dogs and glass bottles are usually discouraged, and local signage should be followed. Outside summer the site is mostly empty, though the riverside path remains popular for walking.
