The Boarderline Downhill is the first trail construction project of Mountainbike Freiburg e.V.. The trail starts at the top of the Roßkopf and leads over around four kilometers and 450 meters in altitude down to the Freiburg youth hostel.
The trail is constantly maintained, but it is not a closed mountain bike trail - so you should expect pedestrians at all times. Also important: The trail is intended as a pure downhill ride. So only ride from top to bottom, never against the direction of travel.
