I had a very nice weekend riding the Naheradweg over 2 days. We started at the Nahequelle (source of the Nahe), continued to Bingen (where the river meets the Rhein), and then home to Mainz.
Would absolutely recommend. The upper part (before Idar-Oberstein) is particularly beautiful, but it's all nice. Mostly on quiet trails with just a little bit of road riding. I found it to be a lot like the Mosel, but fewer tourists and with more hills. A complementary experience!
