 Distinctive signs mark the route at most junctions but acquiring a route map to keep on the journey or a GPS navigation device loaded with the route (available through the official site) is recommended.In Denmark, the path is fully signposted as National Route 9, with red N9 on a blue background.The ferry across the Grønsund runs only during the summer, about 15 May to 15 September, and during a short period in October.
