Swimming Holiday in Slovenia

Slovenian Lakes and River

Join in our Slovenian lake swimming holiday adventure in the heart of Europe. At the junction of the Alps, the Mediterranean and the Pannonian Plain, it will surprise you with its diversity and lush natural beauty. Slovenia is known as a land of pure water, and its numerous green glacial lakes and crystal clear rivers make it a perfect location for our lake swimming adventure.
Trip details:
  • Duration: 4 Days (3 Nights)
  • Tour Type: Lake and River Coastal and Crossing Swimming

We are based in the small secluded town of Bohinj, overlooking the vast waters of its famous lake, which dominate the area. Bohinj provides a perfect gateway for exploring the fantastic landscape of this region and each day of our trip features a varied itinerary of swims and hikes so that our guests get a real sense of what Slovenia’s adventure heartland has to offer.

Our trip takes us through Triglav National Park, swimming in the stunning glacial lakes and exploring the lush forest and magnificent waterfalls. Lake Bled, with its unique island church, cliff-top medieval castle and mountain backdrop, is just one of the highlights of the tour.

This trip is suitable for all levels of swimmers, including non-swimmers and complete beginners. For details about the expected swimming speed please see our FAQs.

At Strel Swimming we pride ourselves on running smaller groups, so we are able to offer a tailored programme for those individuals who may not wish to participate in all the swim adventures. Alternative options are often available to those guests who may wish to combine some walking and sightseeing with shorter swims.

The safety and enjoyment of all our guests is very important to us, so we can provide separate escorted walks around the swimming venues or the chance for a ´dip´ rather than a swim. No motorised boat traffic is allowed on the lakes/river.

– Swim to the 17th century church on Lake Bled
– Swim past Vila Bled, a former holiday villa of Marshal Tito of Yugoslavia
– Swim the length of Lake Bohinj and enjoy the picturesque mountain backdrop

Day 2
We take a short ride to Lake Bled for a day of swimming in its crystal clear water. No motor boats are allowed on the lake so our only companions will be the small rowing boats taking visitors across to Bled’s famous island, home to its small 17th century church. After a short acclimatisation swim in the Zaka bay on the north-western shore of the lake, we swim across to the island where we walk up the ninety-nine steps to enjoy a panoramic view of the lake. Following a short break, we jump back into the water and swim across to the far side where we eat lunch on the beach.

Before our afternoon swim we climb a nearby hill to a viewpoint offering amazing views of the lake and the Julian Alps. Our final swim of the day crosses the full length of the lake (a famous rowing course), finishing at the lakeside Lido where it is time to relax, take a shower and participate in an optional stroke analysis session with your swimming guides. The remainder of the afternoon is at leisure for you to enjoy the lake views, visit the historic castle, or enjoy Bled’s famous ‘kremsnita’ cake in one its many cafes.


Day 3
Today we cross the border into neighbouring Italy, where we swim the full length of the stunning mirror-like Lago del Predil. We take a quick break on the shore before the short drive back into Slovenia for lunch at the popular rafting town of Bovec. We then venture into the remote centre of the Triglav national park and hike through the forest to reach the picturesque Kozjak waterfalls, where we take a refreshing dip in the pool at the base of the falls.

Later, we head to the pristine turquoise waters of the mighty River Soca for a longer swim – an enjoyable contrast to both the thunder of the waterfall and our serene lake swims. Our adventures on this day culminate in an unforgettable journey on the car train, taking you through the Julian Alps back to Bohinj.


Day 4
We start the day with walking around the Lake Bohinj and enjoying the panoramic views of the Bohinj valley, across the lake to Mount Triglav and the Julian Alps. (Mount Triglav is a well-known Slovenian symbol, appears on the Slovenian flag and its 50 cent coin and is Slovenia’s highest peak at 2864m).

We then get ready for our final challenge: swimming the full length of Lake Bohinj (4km). Motorised boat traffic is not permitted on the lake so our only companions are the trout and other fish, which can clearly be seen in the pure water of the lake. A shorter swim (1.5-2km) option is available.


Itinerary changes
Please note that our swims are carried out in the natural environment and we rely on the current weather conditions. As a consequence, sometimes on-trip changes in the planned itinerary are required.

Weather Caveat
Your safety is of utmost importance to us. In the event of adverse weather conditions at any of our swimming locations, we may need to adapt our itinerary or amend some of the swims described above.  Our team always includes local guides who know the safest and most picturesque places to swim, so rest assured you won’t miss out!

Environmental and safety factors in Lakes
Slovenian lakes are clean, fresh water lakes. As with any open water activity, swimmers should always be aware of the risk of Weil’s Disease (Leptospirosis).  The risk of infection in Slovenia is extremely low, but guests should inform their swimming guides immediately if they feel unwell. The incubation period for the disease can be several weeks, so contact your GP immediately if you feel unwell after you have returned home.
