Tour Highlights

  • Join us in the epic Slovenian Alps for an unmissable adventure of freshwater swimming and walking

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

  • Enjoy the challenge of crossing the 4km length of beautiful Lake Bohinj - Slovenia’s largest lake!

  • Cross over into Italy to swim the stunning glacial waters of Lago del Predil

  • Walk forested trails through Triglav National Park to the Kazjak waterfall

  • Swim among the highlands down the glacial-fed Soca river

Ready for a freshwater swimming holiday you’ll never forget? Travel with us to the Slovenian Alps and discover why this country is one of Europe's true hidden gems. Swim the emerald waters of Lake Bled and the crystalline Soca River - take in the stunning scenery of Triglav National Park and even cross the border into Italy to lap Lago del Predil on this unforgettable short escape.

During 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.

To get the most out of this amazing experience, we will combine swims with walks to uncover as much of the local area as possible, occasionally aided by a canoe or rowboat. 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, with mountainous surrounds on the banks of Bohinj Lake, is the perfect place for post-swim recoveries and social meetups. The hotel offers comfortable accommodation, beautiful scenery, friendly staff, and there's even a pool if you just can't get enough of the water!

Who is this camp for?

This trip is for swimmers who love freshwater swimming and inspiring mountain scenery.

Swimmers should have a basic understanding of open water swimming and be capable of completing the average swim distance and average daily swim distance (over the course of two swims) prior to the start of the trip.

We have given this trip a ‘Moderate’ grading. Most swimmers comfortable in the open water will be able to take part and enjoy one of these trips.

Sample Trip Itinerary

Please note that the below daily itineraries are an example of the swims that may take place during your trip, however, actual swim locations and distances will vary according to local weather and swim conditions. Your SwimTrek guides and local boat pilots 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, Slovenia

Start Time: 20:30 on Day 1

Finish Point: Hotel Jezero , Lake Bohinj, Slovenia

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 crosses to Bled Island -home to the Pilgrimage Church - 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.

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 centre, or to simply 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 to find the secluded Kozjak waterfalls.

It’s then time to head to the emerald Soča River – we wade in for a swim where the river has 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 doesn’t stop on the way home either, with a memorable return journey on the rickety car train (an unexpected highlight!), taking us through the countryside to Bohinj and 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 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 who might 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.


Hotel jezero  bled  small
Hotel Jezero

Hotel Jezero is the pearl of Bohinj located on the banks of its picturesque lake. Shadowed by the Julian Alps, this hotel is the perfect base for your weekend of walking and swimming as you can relax back on the hotel deck overlooking the lake or continue your activity in the hotel pool or gym.

Location Summary

Lake Bled

One of Slovenia’s oldest medieval castles overlooks the stunning emerald waters of 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 adventure. The mountain peaks of Pršivec and Storeč Vrh dominate your surroundings. It’s a glacial lake and 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 in Triglav National Park, 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 and Adriatic seas, 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 sits up at an altitude of 960-metres. Fed by Rio de Saletto, the lake is surrounded by trees and rugged cliffs. The water quality here is exceptional and the picturesque views are very hard to top.

Trip Grading

We have given this trip a ‘Moderate’ grading. Most swimmers comfortable in the open water will be able to take part and enjoy one of these trips.

Swimming Distances

Swim Distance Swim Distance
Osojnica – Bled Island 1km Crossing of Lake Bled 2km
Soca River 2km Bled Island - Osojnica ¾km
Crossing of Lago del Predil 1½km Crossing of Lake Bohinj 4km

*Please note that these swims are an example of what may take place during your trip and should be used as a guide only. Actual swim locations and distances will vary according to local weather and swim conditions.

Swimming Conditions

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 Conditions

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.

Weather Caveat

In some countries, tipping (gratuities) is not part of the culture - in others it has become an expected norm. We believe that tipping is done entirely at your own discretion. If you have been provided with excellent service it may be something you wish to do. Your SwimTrek Guides can advise on local norms for service providers like boat crew, waiters or taxis. Nothing is expected for your SwimTrek Guides but many groups like to present something to the Guides at the end of the trip.

Responsible Travel

SwimTrek is conscious of the importance of protecting the world’s natural wonders. We are acutely aware of our responsibility to not only take care of the natural environments which we are lucky enough to explore, but also to educate our guests about the importance of conservation efforts and responsible tourism. It’s for this reason that we have worked so closely with our partners to ensure that our trips are conducted in the most responsible and sustainable way possible, working tirelessly to minimise the impact of our presence on local marine life and the natural habitat.
