Roll out from Parkeerplaats Westlich Berus and the castles start coming: Ruine Burg Siersberg, then Burg Bucherbach and Burg Püttlingen. Between them you slip through Gauberg nature reserve, with Die Ruthenstücker and NSG Eulenmühle / Welschwies further along. At Jagdschloß Karlsbrunn there's another castle, and Westlich Berus nature reserve sees you home. It's 91.1 km with 1055 m of climbing, almost all of it paved.
