Frankfurt City Highlights Tour (10am): Start your day with a sightseeing tour of Frankfurt by double-decker bus, showing you the many facets of the city including its mix of Baroque and modern architecture, lively plazas and impressive skyscrapers.
Listen to your audio guide as you cruise through the Museumsufer (Museum Embankment) and the sleek European banking center, marked by tall skyscrapers that characterize the city's imposing skyline. See the European Central Bank (Eurotower), the Stock Exchange, the Old Opera House and Goethe House, the former home of 18th-century literary genius Johann Wolfgang Von Goethe.
Admire the Romer town hall, constructed in the 15th century and once the site of celebrations during the elections and coronations of emperors. Continue to St Paul's Church, Frankfurt Cathedral (Gotischer Kirchturm) and Hauptwache, a famous Baroque plaza surrounded by modern buildings.
Rhine Valley Day Trip (11:15am): Your Frankfurt sightseeing tour is directly followed by a day trip to the lovely German countryside! You'll explore the UNESCO World Heritage-listed part of the Rhine Valley, from Rudesheim to Sankt Goarshausen.
Travel by air-conditioned coach past romantic villages, pretty vineyards and medieval castles all spread across the massive valley, which stretches 766 miles (1,232 km) from Switzerland to the North Sea.
Stop at a riverside restaurant for lunch (included) before continuing to Sankt Goarshausen, where you'll board a steamer boat for a relaxing Rhine River cruise. Pass iconic Loreley Rock along the way.
Back at the harbor, disembark and head to a wine shop for a wine-tasting session. Sample local wines and learn about local winemaking, and then take time to explore the town's wine bars and shops at your leisure.
On the way back to Frankfurt, stop in Rudesheim to briefly see the Drosselgasse, a 15th-century lane in Old Town. This narrow, cobblestone pedestrian street is brimming with lively restaurants, music venues, wine taverns and gardens.
You'll arrive back in Frankfurt around 7pm.
