There are many mysterious places in the Bohemian Paradise. One of the most mysterious ones includes the caves and rock corridors under the Trosky castle. All the visitors in the past and in these days are attracted to the cave under the castle especially by the legend of a fairy-tale treasure which has been hidden underground under the Trosky since the Middle Ages when the castle belonged to marauding knights. The mysterious Trosky has been magical since the times of the first settlement of this region. It is said to be the sacred place for the mythical Celts.

When you stand at one of the look-out points at the Trosky, have a close look at the surrounding hills. On almost all of them there used to stand a smallish castle, fortress or at least a wooden fort. And each of these buildings had an escape way out. Long time ago, these secret passages and underground underpasses crisscrossed the landscape.

The last time when an old secret passage was discovered was two years ago, directly under the today´s mansion Hrubá Skála. A large castle stood here as early as in the Middle Ages. This secret passage was discovered by chance. On the rock promontory in the rear part of the mansion, in the places where weddings in the open air are held, a part of the soil collapsed at the end of winter.

You can find innumerable mysterious places like these in the Bohemian Paradise. Quite often it is  enough to only have a close look in the surroundings of a historical monument. With your eyes half-shut and dreaming, you might hear the voices of squires at the small defence castle Kavčiny near Valdštejn. No marked tourist trail leads there nowadays. It is the Kavčiny castle that could be the symbol of the by-gone times and the fact that it stands away from the marked trails today only confirms the truth that even when everything around us changes, the mystery of some places remains unchangeable.

Another similar place of your holiday wandering could be Nudvojovice. At the edge of the hamlet there is a splendid little church whose history goes back to the very beginning of the Czech statehood. And much further away, the rock promontory above the Jizera River was one of the ancient connecting points in the landscape. It showed the way not only from the Labe region towards the mountain massive of the Krkonoše but also to the Lužice and the Jičín regions.

The Bohemian Paradise is a pleasant place to live and this was known not only to the old Slavs and mythical Celts. For example the America cave in the Klokočské rocks was inhabited as early as in the prehistoric ages. And when you are in the rocks surrounding the Rotštejn castle, look up and you will see the Kozákov hill towering majestically above you. It is said that you can view one quarter of Bohemia from its top. It can be believed. The mythical hill is full of life nowadays, apart from the look-out tower and everyday paragliding, the visitors are attracted by the deposits of precious stones. Directly below the hill there is an exhibition of precious stones every summer and there is also located a cutting plant. And fairies are said to dance on the meadows below the top at the dawn. Do you not believe it? Do come and enjoy the summer in the Bohemian Paradise.
