End your city tour with a visit to a local tavern to taste its famous Kölsch beer. As an alternative, examine the historic architectural styles on display throughout the Cologne Cathedral during a guided tour.

Ludwigshafen is your gateway to a choice of four excursions. Visit Heidelberg, the perfectly preserved medieval city nestled in the Neckar River Valley along Germany’s Castle Road. Discover the iconic red sandstone Heidelberg Castle and Great Vat, an 18th-century, 49,000-gallon wine cask. For a more active adventure while in Heidelberg, join a guided hike up the Philosopher’s Path, aptly named during the Romantic Period, and enjoy panoramic views of the city. Alternatively, you can visit one of Germany’s oldest cities, Speyer, known for the largest Romanesque cathedral in Europe—a UNESCO World Heritage Site—and the medieval Old Gate, Altpörtel. Or pedal along the river Neckar to the picturesque medieval city center of Ladenburg and enjoy some free time to explore the shops. (B,L,D)

Tour the city by foot or on a guided bike tour that takes you through three countries: Switzerland, France and Germany. Alternatively, go on a full-day excursion to Lucerne, or opt for one of the morning excursions and visit Lucerne in the afternoon. With either Lucerne excursion, you’ll have the opportunity to see its Lion Monument – the figure of a dying lion carved into a hillside in memory of the Swiss Guards massacred during the French Revolution in 1792 – which Mark Twain described as “the most mournful and moving piece of stone in the world.” You’ll also see Lucerne’s spectacular medieval walls and towers, dating back to the 13th century.
