We are based in the Bela Krajina region in southern Slovenia in the small town of Metlika.

We meet at 18.30 (pm) at the hotel lobby for the trip briefing. We go through the trip’s plan and you get to meet other fellow swimmers. Dinner at your choice. We can organise and recommend a venue for an evening meal.
We take a short 20min drive to Kolpa river bank. Before we start our first swim, we do a short 200m acclimatisation swim to make sure everyone feels comfortable swimming in the river. Our first mill-to-mill 2.5km swim takes us from Adlesici (Old Barn dam) to Podbrezje (Kuzma farm dam). The river width is about 100-150m and we follow the spectacular flora and fauna of the protected Kolpa Nature Park.
At Podbrezje we sit down to have lunch overlooking the beautiful river valley. For those interested in history, you will have a chance to look at one of the oldest Slovenian watermills including a sawmill wheel. The mills on Kolpa river (a total of 48 were built in the 18th and 19th century) are an important part of Slovenian cultural heritage and today only two remain active, some remain open to the public.
After an afternoon break, we go back into the river, starting at Fuckovci, where the river steadily flows all the way to Griblje dam. The total swimming distance is about 3.5km with a current assist. On the way, we usually pass local river swans and ducks while hearing birds singing from the trees. On arrival at Griblje dam, we enjoy a local traditional dinner alongside the river bank. Drive back to Metlika.
After a good overnight rest and warm breakfast, we make our way back to the river to continue our wild swimming adventure! We jump back into warm Kolpa at Griblje dam to swim 3.3km towards the Krasinec dam, one of the most scenic dams on the river.
The river valley in this section is incredibly peaceful and green. You hear nothing but birds and will often spot fish underneath you. Kolpa is rich with local fishes and we often meet some on our journey. Overall, there are over 40 different fish species living in the river.
At Krasinec dam we film your swimming stroke for video analysis. Lunch at the local restaurant or picnic on the river’s bank. Before we start the afternoon swim you can try a natural massage under the river stream at the watermill. All you need to do is lie under the river fall at the right place and enjoy the massage!
Our afternoon swim takes us from Otok (Island) mill to Krizevska village mill covering a distance of 2.5km. On the way, we are joined by the Lahinja river at the Big Berry confluence. We follow the lush greenery as we navigate down the crystal clear Kolpa river stream. For most of the swim, you are able to see all the way to the bottom of the river’s bed. On arrival at Krizevska village dam, we have a drink and make our way back to the hotel. Video analysis before dinner with some good tips to help you improve your stroke technique. For the evening meal, we recommend dining out at one of the local restaurants in the old town of Metlika and visit one of the wine cellars. This region is known for producing excellent wine.
For our final day, we head back to Kolpa’s Nature Park to do the longest swim on the trip (4km). We join the Kolpa at Vukovci mill and swim all the way to Vinica dam. On the way, we pass two other mills at Ucakovci where we need to make two short walks around the dams. These short stops are a great way to stretch our legs and rehydrate during the swim. For everyone, it is also a chance to take a break or make the swim shorter if you want. Our escort team follows us on the river as well as on the road. As we approach the Vinica village there is a small bridge and campsite where we aim to exit on the left side. Drive back to the hotel. The trip finishes at around 14h.

NOTE! It is highly unlikely, but in case there would be a substantial water level and flow increase during your trip, we will find an alternative venue to swim for this day.
The water temperature during July and August ranges between 24-26C on the places where we swim, so wetsuits should not be required. However, if you feel more comfortable wearing a wetsuit, please bring it with you. We will help you dry it and have it ready for the next day.
We have limited wetsuits on location to use, but bear in mind that they may not be your perfect fit. If you intend to swim wearing a wetsuit, we recommend you bring your own that you know is comfortable.
Water shoes or Aqua shoes
On this trip we cross several river dams where we need to get out of the river and walk around to the next entry point. You need to have good water shoes that you can put on and off easily to get into and out of the river. There may also be stones and rocks in the river at exit and entry points and shoes with a good grip will help you with your footing. Open flip-flop sandals are not the best option. Please bring something like Aqua Water Shoes.
We do short walks on this trip along the river, usually after lunchtime to stretch legs and we visit some local sights such as: watermills, castles, restaurants, etc. We advise you to bring a good pair of light walking shoes (trainers) as there are some uneven rock surfaces.
Up to 16 people.
In addition to normal items, we recommend to bring the following: at least 2 swimming costumes (one wet, one dry), at least 2 pairs of swimming goggles (one clear and one tinted recommended), sweater/fleece, towel, hat, small daypack, jacket, waterproof sun cream, walking shoes (trainers) and aqua shoes (water shoes).
Your safety is of the 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 at least one local guide who knows the safest and best places to swim, so rest assured you won’t miss out!
Environmental and safety factors in Lakes
Slovenian lakes are clean, freshwater 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.
