From Oberstein Old Town, the route goes steeply uphill past the church-in-the-rocks to the castle. The church-in-the-rocks is a sacred emblem of Idar- Oberstein. It was built around 60 metres high in the rock between 1482-1484, to atone for a fratricide. From there we hike parallel to the “Nahe- Felsenweg” Dream Loop. The route uses narrow paths via spectacular rock formations to provide great views of Nahetal. After a long incline, there comes a very natural section with beautiful, quiet stream valleys, ancient woods and fantastic views when crossing ranges of hills. Due to its length and some steep inclines, this leg is very demanding. Those wanting to break the journey can find accommodation options via the tourist information. The copper mine in Fischbach is worth visiting and can be reached on foot. At the end of the leg we reach Herrstein with its numerous half-timbered houses from the Middle Ages.
