Sokolia dolina is one of the gorges of the Slovak Paradise. It was discovered as one of the last. The first passage (both ways) was held in April 1910. Recorded in 1912 the first winter crossing. In 1913 it marked for the first time. In the period 1979-1981 the transition paths were rebuilt completely, the most significant change is the passing of Zavojovy vodopad (the highest in the Slovak Paradise). Unlike the initial circumvention of the waterfall, the section passes directly today, more than 80 m long system of ladders, bridges and steps. Waterfalls: Bocny, Skalny, Zavojovy, Vysny. Sokolia dolina is part of the State Nature Reserve Kysel.
