Lake Krn, also known as Krnsko jezero, is the largest high-mountain lake in Slovenia and one of the most remarkable natural attractions in Triglav National Park. Lying at around 1,391 metres above sea level beneath the mighty Mount Krn, this glacial lake is surrounded by quiet alpine landscapes, limestone peaks and open mountain meadows. Its clear water, peaceful atmosphere and remote location make it a perfect destination for hikers, photographers and nature lovers exploring the Julian Alps and the upper Soča Valley. Because the lake can only be reached on foot, every visit feels like a true mountain journey and offers a deeper connection with Slovenia’s protected alpine nature.
