The Ploner See Lakeside Trail begins at Schlossberg 5 beneath Plon Castle, about a 15-minute walk from Plon train station, and requires no permit or fee to access. The 12 km loop climbs roughly 60 m up the Schlossberg viewpoint hill before descending to follow the shoreline of the Grosser Ploner See, the largest lake in the Holstein Switzerland Nature Park. The surface is a mix of packed gravel park paths near the castle, a paved promenade through Plon town, and a mostly dirt lakeside track through mixed forest along the eastern shore, which offers good shade in summer; the open promenade and castle hill sections are more exposed to sun and wind. Landmarks along the route include Plon Castle itself, a 17th-century ducal residence perched above the lake, the town promenade with its boat harbor, and a forested stretch near Fegetasche where the lake narrows and birdlife is easiest to spot with binoculars. A natural turn-around point for a shorter walk is the Fegetasche viewpoint, cutting the loop to roughly 7 km. There are no refuge huts on the trail, but the promenade in Plon has several cafes and a public toilet, and drinking water fountains are available near the harbor. The climb to the Schlossberg is the only sustained uphill section and is not technical, following a paved path suitable for most fitness levels.
