The Rhine River stretches through France and Germany and I had the pleasure of traveling through the middle Rhine via boat tour. The tour lasted 1.5 hours and without air conditioning on the boat and being 98-100 degrees Fahrenheit, was plenty of time to be out on the river. The tour featured the main castles of the middle Rhine, which were all large and picturesque and beautifully surrounded by wineries and greenery. The houses, hotels, and businesses lining the river were romantic and Bavarian in design. This river of lush nature and history is worth a visit! Just be warned that many businesses, including restaurants, in the area do not have air conditioning and can be difficult to enjoy a visit.
