Try Speyer EDRY or Schwabisch Hall EDTY or Augsburg EDMA or Hamburg EDDH.
I just love euroga for the great answers one gets. Thanks to everyone and it seems sensible to wait a while until the weather warms up.
Heidelberg hasn’t been mentioned yet… It’s within easy reach from Mannheim, which has an accessible airport but don’t waste your time in the city. I’m a fan of Heidelberg’s old town, though it is quite touristy and you will hear lots of English…
If Düsseldorf ends up on your list and you have spare time (probably not during a shorter trip like that) and feel like meeting up, I’ll be happy to. Düsseldorf is really good on a Wednesday night from very early spring to very late autumn on Ratinger Straße. It’s the nicest place to be among people. Virtually EVERYONE will be out there on the streets, sipping “Alt”, the local beer, chatting, near the Rhine..
Berlin, as others have mentioned, is a different league altogether and is THE place where stuff is just happening.
Fly down South, to Bavaria. There’s no GA airport in Munich but in Augsburg (40 miles) and Landshut (50 miles). I can help you get it organized.
Berlin, Hamburg, Dresden would be my other choices. Dresden is great for GA, and the city is beautiful. For Berlin you fly to EDAZ and take one of the rental cars which are offered in the Tower. There’s also a good hotel at the field, owned by the airport. I do that 2 times/year
Weimar is nice and full of history. There is an airfield near by where you can sleep in small bungalows. Heidelberg is beautiful, too. You can go there by train from Mannheim Airport very easy. For Hamburg I can recommend landing in Uetersen, the public transport in Hamburg is great. Speyer has a nice town and the famous Technikmuseum in walking distance to the Airfield. Everyone of the Frisian Islands is worth a trip, although Juist has the shortest way to the Beach. Leipzig is great and Dresden, too. If you fly south along the Rhine, be sure to fly along the valley from Koblenz to Bingen where the Rhein features many old castles. Best flown low and slow. Münster has many churches and with Osnabrück nearby you have the most important cities for the end of the thirty years war. EDLT or EDWO would to the trick.
