Mlava and Krupaj springs

The foothills of the mountain of Beljanica in eastern Serbia abound in powerful karst emergences. Two such wells are of particular interest due to their power, appearance and the way they emerge: the Mlava Spring, in the village of Žagubica itself, located where the northern slopes of Beljanica descend into the Homolje basin, and the Krupaj Spring (Krupajsko vrelo), at the western foot of the mountain, in the Krupaj river valley some 35 km from Žagubica.

The Mlava Spring is set in a natural amphitheatre which opens towards the northwest via the short valley of the outflow of the emergence. The well is in the shape of a pond some thirty metres across, its water deep green in colour. When at its height, its flow can reach 15 cubic metres per second, when it becomes whitish or reddish and clouded. The water in the pond ascends from a great depth. To date, divers have succeeded in descending the underwater funnel to a depth of more than 70 m without having reached the bottom of the siphon. Once the main water source for Žagubica, and a traditional gathering place for festivals and rituals, the Mlava Spring today is an attractive tourist spot, with tended banks and wooded slopes.

The Krupaj Spring once emerged from a cave with great force, accompanied by a roaring sound, but today is walled over with a concrete water gate, for use by the wool-carding and flour mill that is still in operation today. As a result, the cave mouth has been partially submerged by the pond which has formed. Near to the emergence there is a powerful thermal spring, with a water temperature of 26.50C.

Both water sources are protected as natural monuments of national importance, and include the immediate area, including 6 hectares around the Mlava Spring and 9 hectares around the Krupaj Spring.
