The Vrabinec (German Sperlingstein) is a well-known dominant in the Elbe valley and a nature reserve. From its summit, which you have to climb up in in the last part, you have a wonderful view of the lovely Elbe valley. However, the ascent is quite strenuous and a head for heights is necessary on the summit.
The slopes are very steep, up to 40°. In the upper part, various forms of weathering are visible (needles, columns, frost block huts and slopes, frost cracks and boulder heaps).
The first written mention of Vrabinec Castle dates back to 1403. Archaeologically, the settlement dates back to the 13th century. In 1415 it was bought by Zikmund Děčínský from Vartenberk. In 1444 the castle was conquered by the army of the Lusatian Six Cities Union. It was abandoned in 1515 at the latest.
