Sandy shores and hidden lakes: 10 ways to spend a beach day in Prague and beyond

Prague may be landlocked, but in summer it behaves like a city with a coastline. Heatwaves don’t send people to the sea; they send them to riverbanks, forest reservoirs and biotope pools scattered across the capital and Central Bohemia.

Some of these places feel like beach clubs. Others are quiet patches of grass with water you can actually swim in. Together, they form one of Central Europe’s most underrated summer swimming cultures.

Here’s where to spend a full beach day in and around Prague in 2026.

Set beneath the bridges of Štvanice Island, Baden Baden is Prague at its most relaxed and unpolished. Wooden decks stretch toward the Vltava, sunbeds appear wherever space allows, and the river becomes part of the scenery rather than just a backdrop.

People come for late afternoons that drift into night: drinks, sunsets, occasional DJ sets, and the rare brave swim in the river when conditions allow.

Getting there: Tram connections from Florenc or Náměstí Republiky to the Štvanice / Těšnov area, then a short walk across the island. Or take the pedestrian footbridge between Holešovice and Karlín, and get off halfway.

Come for: Sunset drinks, river atmosphere and central summer energy.

A little upstream, Kayak Beach Bar shifts the focus from swimming to activity. Beach volleyball, paddleboards, yoga sessions and a steady stream of riverside beers make it one of the city’s most social summer hubs.

Getting there: Tram connections to Výtoň, and then down to the embankment at Rašínovo nábřeží.

Come for: Active afternoons and group hangouts, not swimming.

Tucked into a green valley in western Prague, Motol Swim Centre is quietly re-emerging as one of the city’s more interesting swimming spots in 2026. Renovations are ongoing, but the site remains usable, and unusually, entry is free this season.

It’s not polished, and that’s part of its appeal. Temporary facilities, open grassy areas and a natural setting give it the feel of a place in transition: half retro swimming pool, half urban nature escape.

Getting there: Metro Line A or B to Anděl, then tram/bus connections toward Nemocnice Motol. It’s one of the easiest western Prague swim spots to reach by public transport.

Come for: A relaxed, slightly unfinished swim spot with no entry fee.

Hidden in forests on the city’s southeastern edge, Hostivař Reservoir stretches across sandy shores, grassy lawns and designated swimming zones large enough to forget you’re still in the capital.

One side feels lively and social, filled with paddleboards, volleyball and families. The other is quieter, framed by trees and walking paths that make it easy to disappear for hours.

It’s the closest thing Prague has to a full summer lake culture.

Getting there: Metro Line C to Háje (or A to Skalka), then a connecting bus toward Hostivař / Na Košíku / Hostivařská přehrada. From there, it’s a short walk into the forested lake area.

Come for: Full-day swimming, sandy beaches and classic summer crowds.

Lhotka has quietly become one of Prague’s most comfortable swimming spaces. Instead of chlorine, the water is filtered biologically, creating a clear, natural swimming experience that sits somewhere between a lake and a public pool.

Recent upgrades have expanded terraces and improved facilities, making it more comfortable without losing its calm, natural feel.

Getting there: Metro Line C to Háje, followed by a short bus ride toward Lhotka. The whole trip is usually under 30–40 minutes from central Prague.

Come for: Easy-access natural swimming and a clean, relaxed atmosphere.

On the far southwestern edge of the city, Radotín Biotope offers a stripped-back version of Prague’s biotope culture. Smaller than Lhotka and far less crowded, it’s built for slow afternoons rather than full-day social scenes.

The water is clean, the lawns are simple, and the atmosphere rarely rises above a calm murmur.

Getting there: Train from Smíchovské nádraží toward Radotín, followed by a short walk or local bus.

Come for: Reading, swimming and genuine quiet.

A long-standing Vltava fixture, Žluté lázně is part beach club, part public park, part seasonal festival ground. Volleyball courts, bars, food stalls and packed weekend crowds define its rhythm.

Getting there: Tram connections toward Podolská vodárna/Dvorce area, followed by a short walk along the river.

Come for: Social energy, riverside drinks and organized summer chaos.

Tucked between Zbraslav and Radotín, Lipence Lake is a former sand and gravel quarry that has evolved into one of Prague’s most appealing natural swimming spots. With its spacious lakeside setting, clear water and relaxed atmosphere, it feels worlds away from the city despite being just a short trip from the center.

The largest of five former quarry lakes, Lipence has become a popular summer destination for swimming, paddleboarding and outdoor gatherings. Families will find a playground and beach volleyball court, while groups often use the area for community events, teambuilding activities and even lakeside weddings.

It’s the kind of place where you can spend an entire day by the water and forget you're still in Prague.

Getting there: Take a bus from Smíchovské nádraží to Lipenská škola, then follow the roughly 1 km walking path to the lake. Cyclists can also reach it via Route 8100 between Černošice and Zbraslav.

Come for: Natural swimming, paddleboarding and a laid-back beach atmosphere close to the city.

A former sand quarry turned swimming lake, Lhota feels like a deliberate break from inland reality. Pale sand, pine forests and unusually clear water create a surprisingly Mediterranean atmosphere just outside Prague.

It’s one of the few places near the city where “beach day” feels literal.

Getting there: From Černý Most bus terminal, regional buses toward Brandýs nad Labem or Benátky nad Jizerou. From the nearest stop, it’s a short walk through forest paths.

Come for: Real sand, clear water and a proper summer escape.

When Prague wants to fully leave itself behind, it heads south to Slapy. The reservoir stretches along the Vltava, combining forested hills, marinas, beaches and quiet coves into something closer to a coastal landscape than an inland lake.

Some areas feel like summer resorts. Others are almost empty, even in peak season.

Getting there: Buses run from Smíchovské nádraží / Na Knížecí toward Slapy and surrounding villages such as Nová Rabyně. From stops near the water, beaches are usually a downhill walk.

Come for: Weekend trips, boating and full summer reset energy.

Before heading to a natural swimming area, it's helpful to know how water quality is monitored and what current conditions look like. Prague health officials regularly test natural swimming sites for indicators that can affect swimmer safety and comfort.

Those include: Bacteria such as E. coli and enterococci, which can indicate fecal contamination, cyanobacteria (blue-green algae), which may produce toxins harmful to people and pets, water transparency and clarity, and signs of algal blooms. General sensory qualities such as appearance, odor, and visibility.

As of June 2026, water quality in Prague's monitored natural swimming areas is generally good. Water conditions can change quickly, especially after heavy rainfall, hot weather, or algae growth. To stay up to date on swimming water safety, check the latest advisories and water quality reports from the Prague Public Hygiene Authority before you swim.
