Závojový vodopád is one of the highest waterfalls in Slovakia with a total drop of 75 meter. In 5 stages the river Sokoli potok drops down, with a largest single drop of 20 meter. Závojový vodopád is part of the national park Slovenský raj and is located southwest of Letanovce.
From Letanovce drive south over a small road to Slovenský raj and park the car near Kláštorisko, the ruins of a 14th century monastery. From here a trail starts going east and bends to the south. I think there are signs and that the walk takes appr 60 minutes.
At the waterfall Závojový vodopád you can climb to the top over a system of several ladders, difficult to climb!
There are a lot of waterfalls nearby in the national park Slovenský raj, a great area to visit.
