The Treidlerweg is one of the premium hiking trails in Germany (German Hiking Institute):

Discover the “Palatinate jungle”, one of the few wetland landscapes that have international protected status and are still ecologically unspoilt. The circular route takes you along the Michelsbach brook, past fields yellow with irises and green with grass and reeds. Filled with fish and covered in water lilies, the natural ponds are a sight to behold.
