Summer has officially arrived in Prague and nothing says summer like an afternoon by the water. Swimming is actually a really important part of the summer for Czech people and the city of Prague is home to many “koupaliste” (places for outdoor bathing). The downside to many of the more central “koupaliste” is that they can get a pretty crowded, especially when the sun is shining and it can be tricky to swim without having to duck and dive to avoid kids and other swimmers.
One way to avoid the crowds this summer is to venture out a little further and take a splash in one of the many lakes and reservoirs in and around Prague. These natural swimming spots are popular with swimmers as well as those who are just looking for a relaxing afternoon and maybe a quick paddle. They offer visitors a lot more space, a greater sense of seclusion and also the opportunity to take in a little Czech nature.
My 2 favourite “koupaliste” in Prague are Dzban Lake in the Divoka Sarka nature reserve and Hostivar Reservoir. Both locations are easily accessible by public transport from the centre of Prague. They both also offer a huge area of open, clean water for swimming in addition to an expanse of grassy terrain for sleeping, sunbathing, reading, playing a casual game of frisbee or sipping a cold beer.
Dzban Lake
Dzban Lake is a great spot for relaxing and swimming on the southern shore of the reservoir. Visitors can enjoy sun loungers for chilling and sunbathing, family-friendly activities, sports facilities, refreshments, and clean toilets. It’s the perfect place to unwind, have fun, and spend a sunny day outdoors.

Entry fee: 90 CZK
How to get there: The lake is a 15 minute walk from Nadrazi Veleslavin Metro station (A Line), or a 10 minute walk from Nad Dzbanem tram stop (trams 20, 26). See its location on Google Maps.

Facilities:
- Showers, toilets and areas for changing

I visited this place regularly last summer and paid my first visit of 2017 yesterday afternoon. I was impressed by how much they had improved and modernised the facilities since my last visit but most of all I was pleased to see that it still had a really pleasant, relaxed and peaceful vibe. There was plenty of space for swimming and lounging. We were even able to throw a football around without causing anybody any problems.

Hostivar Reservoir
Hostivar Reservoir is set in a beautiful and peaceful location within the Hostivar Forest Park, just a few minutes from the center of Prague. It’s the city’s largest natural swimming area, surrounded by some of Prague’s most stunning nature. The site features both a main beach and a nudist beach, making it a great spot for families, sports lovers, and anyone looking to relax or swim in a natural setting.

Entry fee: 90 CZK
How to get there: The reservoir is a 10 minute walk from Haje Metro station (C Line). See its location on Google Maps.

I have only visited this reservoir once but I was really impressed with it. The surrounding nature is gorgeous and even though it is undoubtedly very popular, its size meant that it didn’t feel overcrowded. There’s even a stretch of golden sand, for those wanting that authentic beach atmosphere.
