Jezerské jazero is a peaceful mountain lake tucked away in the Spišská Magura range in northern Slovakia, and it has a rather unusual origin — it was formed by a natural landslide of flysch rocks. Sitting at 919 m above sea level, this intimate little lake feels like a hidden gem waiting to be discovered.

The lake is compact — 110 m long and 74 m wide — but its well-preserved water surface and lush, marshy shoreline give it a timeless, fairy-tale atmosphere. The banks are carpeted with typical wetland and aquatic plants, including brooklime, water speedwell, and great water dock. In spring and summer the surrounding vegetation is a vivid green, while autumn transforms the scene into warm golden tones. It is a wonderful spot for nature lovers, birdwatchers, and anyone seeking a quiet escape in the mountains.

• Village of Jezersko — the lake lies within the cadastral area of this village and serves as the natural starting point; a gentle, easy walk suitable for all ages.

• The lake has been protected as a nature reserve since 1967 — please stay on marked paths and avoid disturbing the marshy vegetation zones.
• The protected area covers 2.18 ha.

What makes this lake truly special is its geological backstory — it owes its very existence to an ancient landslide, making it one of the most quietly fascinating natural curiosities in the Spišská Magura hills.
