If you want to get a breathtaking view of the Rhine River, then consider visiting Koblenz, a town that sits on the edge of the Rhine.
Frankfurt, Germany is the first German city I ever visited. I actually visited it on a Sunday and all the stores were closed. So I just walked around and enjoyed the architecture. You can do this too as well as enjoy walks along the Main river and across its bridges. Plus there are small neighborhoods to explore as well. I think you’ll like this city as much as I do. And it’s the financial capital of Germany and the capital of its region.
