The Innerste cycle path runs between Clausthal-Zellerfeld and Sarstedt over 105 beautiful kilometers. Advanced culture along the way Numerous sacred buildings and secular mansions are located on the Innerste cycle path. A highlight is the Marktkirche in Clausthal-Zellerfeld – the largest wooden church in Germany. In Hildesheim, St. Andreas with the highest church tower in Lower Saxony, St. Michael's Church and the cathedral with the famous thousand-year-old rose bush are the highlights.
