@jaapio@phpc.social And I mean... I do hope you are planning to travel from Coblenz towards Frankfurt via the Rhine Valley. I recommend the western route. Although the Marksburg is worth a visit. But you can cross the Rhine in St. Goar. The Loreley is IMO much more impressive from below. And if you're into German monstrosities after winning the 1870/71 war against france: The Niederwald-Monument is ... at least providing an impressive view 😁 https://en.wikipedia.org/wiki/Niederwald_monument
