The Prachov Rocks are a rock formation in the Czech Republic that are approximately 5 km (3.107 mi) west of Jičín. Since 1933, they have been a protected natural reserve. The region where the formations are located is called Bohemian Paradise. The formations are made of sandstone, originally in the form of a plateau.

Since its formation over 60 million years ago, the rock has been eroded by wind and rain into the unique forms found at the site. Several of the individual rock towers have inspired names due to their appearance, such as "the Leaning Tower," "Devil's Kitchen," "the Monk", "the Elephant," and "the Eagle."

A chateau called Hrubá Skála is located high up on a rock platform. The original mansion was built in the 14th century but was extensively damaged over the years and re-built several times, finally in the style of a Renaissance chateau. The property is now operated as a hotel and spa.

Kozákov is the highest hill in the area. There are a tourist chalet and a lookout tower. Kozákov was originally a volcano. Thus, it is a place where precious stones are found. The treatment of these gems has been connected with the history of the city of Turnov called “The heart of the Bohemian Paradise” for several centuries.
