Set at the confluence of the Rhine and Lahn Rivers at the borders of Westerwald and Taunus, Lahnstein is also wedged between two UNESCO World Heritage Sites: the Upper Middle Rhine Valley and the Upper German-Rhaetian Limes. The gorgeous forests, wetlands, and meadows provide ample opportunity for hiking, cycling, and relaxing. Among this spectacular nature, several magnificent, fairy-tale-like castles dot the landscape. Highlights include the hilltop 13th-century Lahneck Castle, and the massive, UNESCO-listed Stolzenfels Castle. The enthralling Rheinanlagen Park is another must-see, with its gorgeous river boulevard and grand historic sculptures. Take a river cruise to see all the sites from the comfort of the boat. The wider area is also famous for its wine - make sure to visit some of the nearby estates to taste for award-winning varieties.
