One of the most beautiful corners of the Czech Republic is in Eastern Bohemia: the spectacular Bohemian Paradise . This area of outstanding natural beauty is notable for its many massive rock formations that seem to stick up out of the ground like so many giants, seemingly unsupported and defying all laws of physics. Now a UNESCO Geopark, the region draws hikers and sightseers from across Europe for its stunning sandstone hills, natural bridges, and tall basalt columns and outcroppings, all accessible by a first-rate network of trails and scenic drives. It's a region that also boasts many fine old castles, including Kost Castle and Trosky Castle. Start your adventure in the town of Turnov, home to the Bohemian Paradise Visitor Center, where you can access a great deal of tourist-related information and maps of the region.
