the valley is one of the true treasures of Liptov and definitively one of the most beautiful Slovak valleys. It is connected with Kvačianska dolina valley in one educational trail. Hiking through Prosiecka dolina is quite demanding, a section of it goes across a flooded river bed, especially in the spring. Some sections include ladder climbing. The trail through Kvačianska dolina is comfortable and wide and suitable for smaller children. The Oblazy water mills – an interesting technical monument, are situated at the end of the valley. The upper and lower mills – built at the beginning of the 20th century – have been reconstructed and set into operation, thus giving visitors an idea of the ancient technology of flour milling.
