Natural Swimming Spots in Vienna

Anyone who knows me is well aware that I’m happiest when I’m in or near the water. Summers in my hometown of Vienna can get seriously hot, and public swimming pools are, of course, a great way to cool off.

Vienna has plenty of pools – at least one in every district. But chlorinated water isn’t for everyone. Personally, I do enjoy going to the pool now and then.

Still, during summer, they often get far too crowded for my liking. On days like that, we prefer heading to one of Vienna’s beautiful natural swimming spots.

And there’s another bonus: unlike pools, these natural places are usually free to access. Especially on a hot day after a long day at work, when you just want a quick dip to cool down, paying 6 euros or more for half an hour in a packed pool feels a bit much.

Donauinsel (Danube Island)

Probably Vienna’s most famous recreational paradise – and for good reason!

Originally built in the 1970s and 80s to protect Vienna from recurring floods, the Donauinsel soon developed into one of the city’s most beloved spots for leisure and relaxation.

Stretching over 40 kilometers, the island offers countless freely accessible swimming areas, barbecue spots, and even designated zones for fans of naturism.

A wide variety of restaurants and snack bars cater to hungry visitors – whether you’re in the mood for Italian, Turkish, or Greek cuisine, you’ll find something to suit your taste.

The island is easily accessible by public transport. The areas around Copa Cagrana and the Sunken City are only about ten minutes by subway from the city center.

Those who prefer a quieter vibe will also find their place on the Donauinsel – just bring a bike if you want to reach the more secluded parts.

2. Mühlwasser

A real insider tip: the Mühlwasser is a picturesque old arm of the Danube.

This area is still largely untouched and even on the hottest summer days, it never feels overcrowded.

You can reach it by public transport too, though the bus journey is noticeably longer than to the Donauinsel.

In return, you’re rewarded with peace and quiet – relaxation guaranteed.

The quality of the water is excellent, and plenty of trees provide welcome shade on hot days

At Strandbad Stadlau, there is an entry fee, but you’ll find a well-maintained sunbathing lawn and clean toilet facilities. There’s also a restaurant on site.

Otherwise, food options around the Mühlwasser are sparse to non-existent – so best pack a picnic basket.

3. Strombucht

This is another old Danube arm.

The Strombucht lies in the middle of a residential area and is very popular, so don’t expect solitude here.

There’s no gastronomy to speak of.

Strombucht it’s accessible by public bus, though. As there are hardly any parking spaces, you’d better leave your car behind.

What I love about Strombucht is the little sandy beach that leads into the water – it makes entering the water so comfortable. And kids love digging and building sandcastles here, too.

4. Lobau

The Lobau is part of the Danube-Auen National Park – a true natural gem with riparian forests, ponds, and quiet old river arms.

Swimming is not allowed everywhere, as many parts are strictly protected. However, two ponds are both popular and legally swimmable: Dechantlacke and Panozzalacke.

Both are natural swimming ponds with relatively warm water. The Panozzalacke especially boasts a lovely grassy sunbathing area. Still, you’ll never be alone there in summer – these small ponds are just too popular.

5. Alte Donau (Old Danube)

The Alte Donau is one of Vienna’s most beloved recreational waters. Here, you can swim, bike, paddle, or rent a boat and explore the surroundings from the water.

Numerous swimming spots along the shoreline invite you to take a dip, and the water quality is generally good. Just like at other spots, you’re unlikely to have the place to yourself.

Alongside the free bathing areas, there are also traditional swimming facilities where you pay an entrance fee but get to enjoy various comforts like food options, tidy sunbathing areas, changing rooms, toilets, lockers, and more.

6. Donau -Oder Kanal (Danube-Oder Canal)

The canal was originally planned to link the Danube and Oder rivers but was never completed.

You can swim here, but there are definitely nicer swimming spots in Vienna. These days, the canal is mostly visited by anglers.

If you happen to be in the area, though, and feel like cooling off, go for it.
