Boller Castle and the surrounding woods are a favourite local outing. A good way to go is via the Planet Path from the centre of Horsens to the castle (approx. 3 km), where you'll gain a new appreciation of the vast distances in the solar system on the way. The inside of the castle is not open to the public, but you are free to explore the beautiful garden and meander along the forest road through the valley to Boller water mill. (approx. 2,5 km)
From April 1 to October 15, the garden is open daily from 10.00 to 20.00.
