After check in, we headed to the nearby town of St Goar, where we visited the Rhienfels castle ruins. Lesson learned: ruins are much more interesting when you know what you are looking at. Lesson two: Rick Steves is not the best at giving directions. We did wander around and see some cool things, but really feel that we would have gotten a lot more out of it if there had been a tour guide pointing things out for us.
There were sort of Boy Scouts camping out at the camp, which must have been awesome for them....but took away somewhat from our visit. Oh, well. Still an awesome view from the castle, and pretty extensive ruins to wander through.
