Tour Highlights

  • Join us in this fabulous location for a ‘packed to the rafters’ short break away of freshwater swimming and walking

  • Swim to the picturesque 17th Century pilgrimage church on Bled Island

  • Enjoy the challenge of swimming the 4km length of beautiful Lake Bohinj, Slovenia’s largest lake

  • Cross over into Italy to swim in the stunning Lago del Predil

  • Walk along stunning trails through Triglav National Park to dip in the cool waters of the Kazjak waterfall

  • Swim down the glacial-fed Soca river

Enjoy a freshwater swimming holiday in Slovenia and discover why the country is considered to be one of Europe's true hidden gems. Swim in the emerald green waters of Lake Bled and the crystal clear Soca River, take in the stunning scenery of Triglav National Park and even cross the border into Italy to swim Lago del Predil on this unforgettable short escape.

On this trip we’ll be based in the small town of Bohinj, the central hub for all our excursions by land and water. This includes a swim to the 17th Century church on Bled Island, crossing the beautiful Lake Bohinj, and exploring the National Park and Kazjak waterfall by foot.

To get the most out of this amazing experience, we will be combining swims with walks to see as much of the local area as possible, with occasional help from a canoe or rowboat. In order to experience the best swimming that Slovenia has to offer, we spend time travelling to and from different locations, which makes for quite a busy trip, with evening returns to the hotel on Days 2 and 3.

With such an action-packed four day adventure, we know it's important to recharge your batteries and the Hotel Jezero on the banks of the Bohinj Lake is the perfect place for it. The hotel offers comfortable accommodation, beautiful scenery, friendly staff and there's even a pool if you just can't get enough of swimming.

Daily Itineraries

Please note that the below daily itineraries are an example of the swims that may take place during the course of your trip. However, actual swim locations and distances will vary according to local weather and sea conditions. Your SwimTrek guides and local boat pilot will determine the most suitable swim locations each day and will communicate the plan with all guests as soon as possible.

Trip Schedule

Start Point: Hotel Jezero, Lake Bohinj.

Start Time: 20:30 on Day 1

Finish Point: Hotel Jezero, Lake Bohinj.

Finish Time: 14:00 on Day 4

Day 1

We meet at the hotel bar for welcome drinks and a short briefing on the plans for the rest of the trip. The acclimatisation swim is held the next morning.

Day 2

We take a short van journey into Bled where we hold an acclimatisation swim, followed by a day of swimming in this famous lake. The first swim is across to Bled Island, home to the Pilgrimage Church and where we’ll walk the 99 steps to enjoy the stunning view. It’s then back into the water as we cross to the lake’s western shore where there will be time for a technique advice session with your swim guides.

After a stop for lunch, we take an optional 20-minute walk up the steep path to Mount Osojnica, which offers stunning views of the lake and the surrounding mountains. On our return to the shore, we swim a full length of the lake, finishing at the lakeside lido. The late afternoon/evening is free for you to either enjoy the view over Lake Bled from the medieval castle, get lost in the shops, cafes and restaurants of the town center or to relax by the lake, before meeting up again to travel back to the hotel.

Day 3

After breakfast we have a 1.5-2 hour scenic van transfer into Italy and onto the shores of the idyllic Lago del Predil for the first swim of the day. It’s then a short drive back into Slovenia for lunch at the popular alpine town of Bovec. Following this, we head into the remote centre of the Triglav National Park, and take a 20-minute walk for a cool, exhilarating dip underneath the secluded Kozjak waterfalls.

It’s then time to head to the emerald green Soča River, for a swim where the river enjoys a gentle current. The scenery is outstanding and the river swim makes a striking contrast to the lakes of the previous few days. The adventure continues on the way home, with a memorable return journey on the car train, taking us through the countryside to Bohinj arriving back in time for dinner.

Day 4

After the previous days, we have an early chance to stretch our legs, as we walk the length of Lake Bohinj. Following the walk we swim the 4km length of Slovenia’s largest lake. We may be accompanied by the schools of wild trout which frequent the lake. The dark green forests and surrounding mountain peaks guide our way. There are suitable get-out points along the way for those that would prefer a shorter swim. The swim finishes within 50 metres of the hotel, where you will be able to use the hotel’s sauna and shower facilities from 2pm to finish off your trip.

Location Summary

Lake Bled

One of Slovenia’s oldest medieval castles overlooks the stunning emerald-green Lake Bled. The lake is home to Slovenia’s only island, which is one of the iconic images of this country. The town of Bled offers a great place to relax after a busy day’s swim.

Lake Bohinj

This is Slovenia's largest lake, which lies to the west of Lake Bled. It’s one of the region’s hidden gems and an ideal base for our tour. The mountain peaks of Pršivec and Storeč Vrh dominate the surroundings. It’s a glacial lake and also a great place to relax and enjoy the serenity that this area offers.

Julian Alps

The Julian Alps, named in honour of Caesar, form Slovenia’s dramatic northwest frontier with Italy. They are located in Triglav National Park which is named after Slovenia’s highest peak (2864m). The Sava and Soča rivers, which we cross during our tour, are the largest two in the region. They rise in the Julian Alps and then flow down to the Black Sea and Adriatic respectively.

Triglav National Park

First protected in 1924 and now covering some 838 km², the Triglav National Park is the only National Park in Slovenia and one of Europe’s oldest parks. Named after its highest mountain, it covers 4% of Slovenia's total land mass and is almost entirely covered by the eastern Julian Alps.

Lago del Predil

Located just 2 miles from the Slovenian border in Italy, this idyllic and remote lake is at an altitude of 960m. Fed by Rio de Saletto, the lake is surrounded by trees and cliff faces. The water quality is exceptional and the views unsurpassed.

Environmental Lake Swimming

These lakes are some of the world's cleanest freshwater lakes, however water quality can be an issue with water runoff from fields. Bluegreen algae and Weil’s disease are all possible contaminants. If you do feel unwell at any stage during or after the trip, you should go to your GP immediately, telling them what you have been doing.

Walking Distances

Most walks take place on recognised paths and tracks, however there may be cases where we walk along trails or other unsealed surfaces and care should be taken in these areas. The walk on Lake Bled gets quite steep and rocky towards the top, so a pair of sturdy trainers or walking sandals will be required.


Please note that, due to this area being an alpine region, weather conditions are unpredictable and temperatures can drop overnight. Therefore, the temperatures below are indicative and should be used as a guide only.

Weather Caveat

For safety reasons, we rely on decent weather conditions when carrying out our swims.

  • My first but definitely not my last SwimTrek - I rediscovered my love of swimming after a wee break from it, thanks to beautiful Slovenia and brilliant guides and fellow swimmers :)

    Renee, Italy - 2019
  • The whole experience was amazing. There was a perfect combination of swimming, hiking and time to explore the local area. The trip was a fantastic way to experience Slovenia and was incredibly well organised.

    Katherine H, UK - 2019
  • It’s all too easy to get caught up in the day-to-day of life and its perpetual demands, to then lose sight of what’s most beautiful while providing for our loved ones and our selves. SwimTrek restores that vision, reminding if not showing us what riches can abound in and around the water: Nature, adventure, wonder, health, camaraderie, and community. Thank you, SwimTrek, not for the trip of a lifetime – because I’ll soon take another with you – but for a trip that’s life affirming.

    Beowulf S, USA - 2019
  • My first experience of Swimtrek was amazing! I loved every minute of it. From the briefing through to the end of the trip it was non stop fun - we packed so much into each day! Our guides Kelly and Sarah were incredible, making sure everyone was able to swim at their own pace and moving seemlessly from one activity to the next even when faced with some pretty unusual weather! I'll definitely be back.

    Anna, UK - 2019
  • Don't hesitate, book, do the training and have the experience of a lifetime. Just incredible, loved every single second, and cannot wait to do another one. Thank you swimtrek - you were brilliant!

    Rebecca L. IRL- 2018
  • There was a moment on this holiday when swimming flipped from being something that served a purpose to something I fell in love with. Swimming in the crystal clear Lake Bohinj with the sun on our backs is a memory I won’t forget. Absolutely amazing.

    Graham S. UK- 2018
  • Swimming in the crystal clear waters of Lake Bled and Lake Bohinj was a truly life-affirming experience.

    Michael S. UK- 2018
  • I signed up for this trip as I wanted to get fit, loose some weight and achieve something for myself after having my gorgeous baby 10 months ago. I swam 4 km down the length of beautiful lake Bohinj. I have made new friends, I feel fit and positive about myself, I have lost 1.5 stone through all my training and am very proud of myself! Thank you swimtrek!

    Mary C. UK- 2018
  • The sense of achievement I got after swimming the 4km of the beautiful Lake Bohinj is still making me smile a week after coming home.
