Ivarčko jezero is a small artificial lake tucked beneath Uršlja gora in the Ravne na Koroškem municipality. It holds the distinction of being the lowest-lying alpine lake in Slovenia, making it an easy and rewarding stop even for casual visitors.

The lake covers 1.2 hectares and reaches a maximum depth of 5 meters. Surrounded by greenery and framed by views toward the surrounding hills, it once hosted a well-kept recreation center with sports courts, sunbathing areas, and a proper beach. In recent years the area has fallen into disrepair, awaiting a new owner with a vision to revive it. Still, the lake itself retains a peaceful, natural charm and makes for a pleasant stop on a walk or bike ride through the Koroška region.

How to get there

• From Koteljami, following the road past the former small spa Rimski vrelec - about 3 km, an easy route also accessible by car

The lake lies close to the former lower station of the chairlift serving the Ošven ski slope, giving the area a winter character too during the ski season.
