Head out into Denmark’s second national park, the Mols Hills (Mols Bjerge) on the Djursland peninsula. Explore its hilly heathland, dotted with mulberry bushes, bogs, beach meadows and interesting sights, such as the ruins of Kalø Castle.
The area around Silkeborg and Skanderborg is known as The Lake District and here you’ll find Denmark's longest river, Gudenåen, and Denmark’s highest point, Yding Skovhøj. The area is also covered in a large number of beautiful lakes and you can take in formidable views across the whole region from The Sky Hills (Himmelbjerget) near Ry.
South of Viborg, in spectacular unspoilt landscape, you can visit Hald Lake and walk in the protected Dollerup Hills. To the west of Viborg is Kongenshus Memorial Park, with its impressive moorland as far as the eye can see. The soil is sandy and chalky and lime has been extracted from the areas around Mønsted and Daugbjerg for centuries. The abandoned mines and their network of tunnels are open to the public. If you’re feeling brave, head down into the dark and look for the large bat colonies that live deep underground.
Grejsdalen is a valley northwest of Vejle and Denmark's largest gorge. Walk in this unique scenery, with forest-covered slopes running down to the Grejs River. Close by are more beautiful valleys, such as the Vejle Stream Valley (Vejle Ådal) with great walks and trails.
