De Grønne Rails
De Grønne rails is a set of green rails in assorted lengths and steepnesses. There are high rails with kinks as well as knee high and short rails.
These rails are located in the eastern part of Hillerød. Go towards the hospital. Drive around. There are two roundabouts - at one of them there is a "Prima" supermarket. The green rails are right by that Prima supermarket (up the hill)
