The world-famous gorge is located close to Zasip. The gorge was carved by the Radovna river between the hills of Hom and Boršt. The 1.6km gorge ends in the 13m Šum waterfall. A stone railway bridge, built between 1904-1905 and designed by the architect Robert Schonhofer, crosses the gorge just before the waterfall. The bridge is 33m high and 65m long; its main arch measures 41m. A stroll through the gorge offers an exceptional experience for anyone interested in plants, animals, and geology. The 110-year old hydroelectric power plant which is located beneath the waterfall was built to supply energy during the construction of the Bohinj railway, particularly for the Hom and Karavanke tunnels.
