Roll out of Simbach am Inn and let the ride unfold: first the nature reserve at Untere Alz, then along the Salzach river to Schloß Wanghausen. Next comes Burg zu Burghausen, followed by the Vogelfreistätte Salzachmündung nature reserve and Ratzlburg castle. The Inn river and Herzogsburg round things off before you roll back into Simbach am Inn. All 68.7 km is paved, with 425 m of climbing along the way.
