1. Heidelberg 6-Hour Tour from Frankfurt
Enjoy a morning tour to the romantic city of Heidelberg situated on the River Neckar, one of the most beautiful cities in Germany. It's simply magical. Visit the world-famous ruins of Heidelberg Castle, a stunning combination of architectural styles stretching from the Gothic period to the Renaissance. Stroll through the expansive courtyard and admire the views from the imposing terrace. Marvel at one of the largest wine barrels in the world. You then wander through the medieval town center. Here you will see the Old Bridge, the Karlstor, and the Church of the Holy Spirit. Admire the Haus zum Ritter (Knight's house) with its magnificent Renaissance façade and discover the old narrow lanes with their half-timbered houses. Heidelberg is also home to Germany’s oldest university and is full of interesting stories. And if you still have some time to spare, you can philosophize on Philophenweg (Philosophers' Way) or discover the excellent regional wines – the two go together quite nicely.
