Next to Kobarid, in the Triglav National Park, you will find the Alpine Krn Lake. The lake is not only the most beautiful glacial lake in the Krn Mountains (2,244 m) but also the largest glacial lake in Slovenia. It is only accessible by hiking and every year, countless tourists admire it.

The solitary lake is 300 meters long, 150 meters wide, and offers a perfect view of the surrounding barren mountains (Julian Alps). The deepest point of the lake is 17 meters.

Swimming and fishing are prohibited in the lake due to its very sensitive ecosystem.

More about Lake Krn

The water is home to 40 plant species, mostly algae, and 24 inferior animal species, dominated by tiny crustaceans. The area around the lake is full of vibrant, colourful alpine flowers, including endangered species.

The Krn Mountains and Lake Krnsko were once the sites of the bloody events of the Isonzo Front and the dark period of the Rapallo border. The remains of ditches, caves and barbed wire testify to WWI.

The greenish lake fits in perfectly with the alpine landscape. It is a picturesque place that many photographers visit. If you’re lucky enough and there aren’t many tourists, fabulous pictures can be taken.

Good to know: The plural form of Krnska Jezera refers to Lake Veliko (Krnsko), Lake Dupeljsko and Lake Ložnica.
