The usual approach is the passenger boat from the Seelände landing in Schönau am Königssee, about 35 minutes each way. There’s a car park by the mainland landing, not at the church. A several-hour alpine hike is the only foot approach in summer, so the boat is the practical choice for an ordinary visit. Church admission is free, but boat travel is charged separately. Boats normally run year-round unless the lake freezes; fog, storms, high water and other disruptions can affect service. Sunny weekends and holidays bring queues, so go earlier and leave room for your return trip. Check the timetable before setting out.
