Zamkovského hut was built by an avid mountaineer and mountain guide Štefan Zamkovský. Despite the communist nationalization, it did return to his descendants after 1992. It's now a sought hiking destination especially by families with children as the hike is quite non-challenging. On your way there you can also encounter the Great Waterfall.
