Zurich's Lakes and Rivers Are Open for Business — Here's How to Get Started in Water Sports

Zurich sits on one of Europe's most swimmable urban lakes, and this summer the city's outdoor bathing facilities — the famous Badis — are reporting their highest early-season attendance in at least five years. The numbers tell the story: the Zürichsee shore counted over 12,000 visitors across its public bathing stations during the final weekend of June alone, according to figures from Stadtwerk Zürich. For anyone who has not yet taken the plunge, literally or otherwise, the window to start is right now.

The timing matters for reasons beyond sunshine. Water temperatures on Lake Zurich hit a comfortable 22°C last week, a threshold that coaches and clubs generally regard as ideal for introducing adults to open-water swimming. The city has quietly invested in aquatic infrastructure over the past three years — new changing facilities at Strandbad Mythenquai on the western lakeshore opened in May 2025, and Seebad Enge, tucked beneath the Quaibrücke on the left bank, completed a refurbishment of its wooden deck and entry pontoons in April this year. Both are within a 15-minute tram ride from Zurich Hauptbahnhof.

Where Beginners Actually Go First

Most first-timers in Zurich get pointed toward one of two organisations. Schwimmschule Zürich, which operates courses out of the Hallenbad Altstetten on Hohlstrasse, runs adult beginner swim courses every six weeks starting at CHF 185 for a seven-session block. The school has been placing adults in open water since 1998 and typically graduates around 400 new adult swimmers per year through its structured programs. Hallenbad Altstetten stays open until 9 p.m. on weekdays, which solves the problem of working around office hours.

The second entry point is the Limmat itself. The river cuts straight through the city from the Zürichsee northward, and floating or swimming the Limmat — known locally as Limmat-Schwimmen — has become something of a civic ritual on summer evenings. The Flussbad Oberer Letten, a restored industrial bathing site in Kreis 5, is the most popular starting point. Entry costs CHF 8 for adults, and the current does most of the work. Lockers, showers and a small kiosk are on-site. Current checks are updated daily on the city's water sports portal at stadt-zuerich.ch/sport.

For those wanting to move beyond basic swimming, the Zurich Kayak Club — Kanuclub Zürich, based at Werdinsel near the Höngg district — offers introductory paddling courses on the Limmat starting at CHF 120 for a two-day weekend module. Stand-up paddleboarding has its own entry infrastructure: ZüriSUP, operating from a trailer at Tiefenbrunnen on the eastern lakeshore, rents boards from CHF 25 per hour and gives complimentary 20-minute safety briefings with each rental.

What You Actually Need Before You Go

The practical checklist is short. For lake swimming at any of the Badis, no equipment beyond a swimsuit is required — but a tow float, available at most outdoor sports shops on Bahnhofstrasse or at Ochsner Sport near Bellevue for around CHF 30, is worth having for open-water visibility. Wetsuit rental is available at Tiefenbrunnen from late May through September, typically at CHF 18 per session, useful in early season when water temperatures are still below 18°C.

Water quality on both Lake Zurich and the Limmat is monitored weekly by the Cantonal Laboratory of Zurich. The lake has met EU bathing water standards consistently since 2019. The data is public and updated Tuesdays on the canton's environmental portal.

The Badis begin winding down their extended hours after mid-August, so there are roughly six weeks of peak conditions remaining. Schwimmschule Zürich's next adult beginner cohort starts 14 July, with registration still open online. For anyone sitting on the fence, the infrastructure, the water quality and the calendar all point in the same direction.
