The Blederija is a natural monument in eastern Serbia. It was placed under the state protection as the geological phenomenon and includes various geological formations in the watershed of the Blederija river, on the Miroč mountain.
Location
The reserve is located on the central-eastern slopes of the Miroč mountain. The waterfall, as the central feature of the area, is away from the closest village, Reka, from Brza Palanka and from the municipal seat of Kladovo.
Geography
The Blederija river springs from four karstic springs on the Miroč, at an altitude of, under the Topla Bara peak. The springs are away from each other. Some are icy cold, while the others are sub-thermal - one has a water temperature around, the other has a constant. The river forms several cascades in the heavily forested area before forming the tall Blederija waterfall after the flow of. Water falls over the tufa bar in the curtain style, forming the plunge pool in the form of tufa tub. It holds small lake with turquoise water color. Downstream there is another, even shallower lake. From there, after several cascades, the stream reaches the valley. There are several caves left of the waterfall and the scenic viewpoint on the location of former medieval town. The largest is the Sokolovica cave, from which the brook of the same name springs. It is away from the waterfall, downstream of the former town. The cave is neither arranged nor opened for the visitors. The Blederija continues in the southeast direction and receives rivers of Sokolovica and Suvaja. It's total length is only. After receiving the Ravna reka, it continues into the Danube under the name of Račka Reka or simply the Reka. The average discharge varies greatly and during the catastrophic 2014 Southeast Europe floods, the river heavily flooded its lower valley causing damage. However, during the normal water levels, the river can be crossed on foot in some sections, though there are several small bridges across it.
The area is today heavily forested and scarcely populated, but in the Roman period, the legionaries built a road through this valley, as a shortcut between the locations where the modern Danubian towns of Donji Milanovac and Brza Palanka are. It was used by the Roman army until the emperor Trajan cut the road through the Iron Gates gorge itself. The town was located on the river during the Middle Ages. The locality is today known simply as "Grad". According to the folk mythology, the water fairies bath under the waterfall.
Protection
The Blederija river's watershed was declared a natural monument in December 2019. Richness and variety of the complex's geodiversity are named among the reasons for state protection. The protected area includes four springs which form the river, a natural reservoir in the lower section of the river valley, the Sokolovica spring cave, a small limestone gorge and the water cascades. The area is placed in the II category of protection. Total protected area covers. Of that, is privately owned. Just north of the protected area is the much larger Đerdap national park, which includes the long Iron Gates gorge carved by the Danube, and northern section of the Miroč mountain. Established in 1974, the park was declared the first UNESCO global geopark in Serbia in July 2020.
Tourism
Until 2019, Belderija was almost unknown to the non-local population and was nicknamed :the best kept secret of Đerdap". Number of visitors grew since it came into the spotlight thanks tothe establishment of the natural reserve. Plans are made to build the proper road into the reserve, direct access path to the waterfall, tourist signs, guardhouse, etc. However, environmentalists pointed out that, even still rare visitors, litter the area, leaving plastic bottles and bags, and that access maybe should be limited.
