2 Best Sights in Alken, The Rhineland

Genuinely medieval (12th–16th century) and genuinely stunning, Burg Eltz deserves as much attention as King Ludwig's trio of castles in Bavaria. For the 40-minute English-language tour, ask at the souvenir shop. This on-request experience guides you through the period rooms and massive kitchen, as well as a treasure vault filled with gold and silver. To get here, exit B-416 at Hatzenport (opposite and southwest of Alken), proceed to Münstermaifeld, and follow signs to the parking lot near the Antoniuskapelle. From here it's a 15-minute walk, or take the shuttle bus (€2). Hikers can reach the castle from Moselkern in about an hour.

This 12th-century castle towers over the village and the Burgberg (castle hill) vineyard. Castle tours include the chapel, cellar, tower, and a weapons display, and wine and snacks are served in the courtyard. Allow a good half hour for the climb from the riverbank.
