The Dutý Kámen nature preserve is located to the east from Cvikov. The noteworthy geological phenomenon - in English: Hollow Rock, is sandstone decomposed into unusual tiny columns. The little columns in a fan-like arrangement are 2 - 5 cm wide and up to 3 m high. The phenomenon is best visible from the 2.5-metre high rocky gnarl nearly in the middle of the ridge.

There is an old pathway on the rock ridge, with remnants of steps carved in the rock, and the path that will take you to the Karolínin Odpočinek, a platform to relax and look around, with a stone bench decorated with a relief of a crown. The neighbouring rock hides a small cavern. Just behind the platform you will come across the already mentioned rock mound with sandstone columns, sometimes nicknamed the Varhany (Organ).

The rocks at the southern end of the ridge will reveal a small yard where a relief of a head decorated with laurels, a lyra and a sword was carved in memory of the 100th anniversary of Theodor Körner, the poet. Next to the relief, there is a staircase carved in the rock that will take you to a lookout rock called Široký Kámen (i.e. wide rock): its top is equipped with an octagonal stone table and a bench. There used to be an astronomical-geographical orientation map and a sundial but the only preserved part of it is the clock face.
