High mountain lakes

Why are high mountain lakes not for bathing?

High mountain lakes in Triglav National Park are among the most beautiful natural sights in Slovenia. They are clear, quiet, fragile and often look so inviting that visitors may feel tempted to swim in them.

Please do not do that. Bathing in high mountain lakes is not allowed because these lakes are extremely sensitive ecosystems. They are small, cold, slow-changing and much more vulnerable than larger lakes in the valleys.

High mountain lakes should be admired from the shore, photographed respectfully and left undisturbed. Their beauty depends on clean water, natural balance, silence and the absence of human disturbance.

Do not swim, wash or rinse anything in high mountain lakes

Swimming is not the only problem. Washing yourself, washing dogs, rinsing dishes, cleaning clothes, using soap, sunscreen, shampoo or other cosmetics in high mountain lakes and streams can damage the water ecosystem.

Even if the water still looks clear after one visit, repeated human use can slowly change the lake. Nutrients, oils, cosmetics, dirt and microorganisms can encourage algae growth and disturb the natural balance of these fragile alpine waters.

This is why high mountain lakes must be experienced with respect: look, breathe, photograph, enjoy the view, and leave the water untouched.

Seven Lakes Valley and Triglav Lakes

The Triglav Lakes, also known as the Seven Lakes, are one of the most famous high mountain lake areas in Slovenia. They are a symbol of the Julian Alps and one of the most precious parts of Triglav National Park.

Because these lakes lie in the protected high mountain environment of the park, bathing and other recreational activities in the lakes are not allowed. This also applies to dogs.

If you hike towards the Seven Lakes Valley, please stay on marked trails, do not enter the water, do not wash anything in the lakes, do not leave waste behind and do not disturb the peaceful alpine environment.

Zelenci Nature Reserve

Zelenci is not a high mountain lake, but it is another very sensitive water environment near Kranjska Gora. Zelenci is a natural reserve and the source of the Sava Dolinka River, known for its emerald-green water, wetlands and protected natural features.

Visitors should enjoy Zelenci from the maintained trail and wooden footbridge. The footbridge exists so that people can experience the lake and marshland without damaging the sensitive wetland ecosystem.

Please do not enter the water, walk into the marsh, leave the marked path, disturb animals or damage plants. Zelenci is a place to observe, not a place to swim.

Waterfalls and streams around Vršič and the Julian Alps

The area around Vršič Pass, Kranjska Gora, Trenta, the Soča Valley and the Julian Alps is rich in waterfalls, streams and clear mountain water. These places are beautiful, but they also need respect.

Some waterfalls and river sections may have official viewpoints, marked paths or designated areas where visitors can safely enjoy the water environment. Other places may be dangerous, protected, slippery, narrow, exposed or unsuitable for entering the water.

Please follow local signs and rules. Do not climb over fences, do not walk into closed areas, do not wash dishes or clothes in streams, and do not use soaps or shampoos in natural water sources.

Water near Erjavčeva koča

The stream near Erjavčeva koča mountain hut is not just part of the landscape. It is an important water source for mountain huts on Vršič Pass.

This water is essential for daily life in the hut. It is used carefully and responsibly because mountain huts are not connected to unlimited valley water systems. In a mountain environment, every litre of water matters.

Please do not wash, bathe, rinse clothes, clean equipment, use soap or let dogs enter water sources near the hut. Protecting water sources helps protect the hut, visitors, staff and the natural environment.

Where can visitors swim instead?

If you want to swim, choose official natural swimming areas in the valleys where bathing is allowed and managed. These places are better suited for swimming and have clearer rules, safer access and less impact on fragile high mountain ecosystems.

High mountain lakes, protected streams, waterfalls and water sources should be treated differently. They are places to admire, not places to bathe.

Respect water as life

Water in the mountains is not only beautiful. It is life for plants, animals, people, mountain huts and entire ecosystems. Clean water supports alpine lakes, streams, wetlands, wildlife, livestock, forests and visitors.

By not swimming in high mountain lakes, not washing in streams and not disturbing water sources, you help protect one of the most important natural treasures of Triglav National Park.

Final advice

Admire high mountain lakes from the shore. Walk respectfully around Zelenci. Enjoy waterfalls from safe and allowed viewpoints. Protect streams and water sources near mountain huts.

The best way to enjoy mountain water is to leave it clean, quiet and alive.
