The Krnsko jezero lake

The largest mountain lake in Slovenia lies at an altitude of 1391 m.

Access to the Krnsko jezero lake

18 km out of Bovec, there is a clearly marked, well maintained rocky trail. For the most part, it leads through the forest and will bring you to the Dr. Klement Jug House in Lepena. Uphill hiking time: 2.5 hours. Difference in altitude: 690 m.

This glacial lake is situated under Krn (2244 m), not far from the mountain lodge at Krnska jezera lakes (1385 m), the Duplje plain and the Dupeljsko jezero lake.

The Krnsko jezero lake is close to 400 m long, 150 m wide and up to 17 m deep.

It provides a habitat for 40 plant species – mostly algae – and 24 species of lower animals, predominantly small crayfish. Swimming is prohibited in order to protect the lake's ecosystem.

The lake offers beautiful views of Krn and the nearby summits. The lake is surrounded by colourful mountain flowers, including several endangered species such as the yellow Kerner Alpine poppy (P. alpinum subsp. kerneri), a species of aconite (Aconitum angustifolium) and white cottongrass (Eriophorum scheuchzeri).

The memory of the Isonzo Front is kept alive by the remains of fire trenches, caverns and wire fences.

The plural name of the Krnska jezera lakes refers to the Veliko (Krnsko) jezero lake, the Dupeljsko jezero lake and the smaller Jezero v Lužnici lake.
