We stopped at the Niederwald Monument after having walked the nearby trails that day. The monument is very well done and I appreciated that all of the signs were in English. I thought the displays did a nice job laying out the history of the monument and its connection to King Wilhelm and the WWII years (Hitler even held a rally here in 1933!). First, make sure you ride the Seilbahn tram up to the monument, as you’ll get great pictures of the monument behind the many vineyards. At the top, you’ll have the chance to see some great trails and see some fantastic views of the Rhine. Finally, there were bathrooms and a small cafe up near the monument as well. Highly recommend you visit Niederwald Monument.
