Vltavou until you reach the dam of the Lipno lake, cross it, turn right at the end and continue along the right bank of the Lipno lake about 16 km through Přední Výtoň to the village of Svatý Tomáš, where you park at the church. The red hiking trail will lead you along a forest path with a slight incline to the ruins of Vítkův Hrádek Castle (about 300 metres).
Vítkův Hrádek Castle
The castle was founded by Vítek of Krumlov in the middle of the 13th century. It is the highest placed castle in Bohemia (1,053 m above sea level) with the largest preserved residential tower, the so-called Donjon, measuring 17.5 x 14 metres.
In winter season, the castle's residential tower is open only on weekends, but in good weather the observation deck offers the most beautiful views of Šumava, Lipno lake and the Alps in Austria. On weekends, you can also buy small refreshments in the castle area.
