If you have a few weeks before you go, you still have time to order a copy of the Flieger Taschenkalender from any German flying shop on the web for 18 euros. This compact handy little blue book, is a real help to touring Germany. It is a mini-AIP with detailed airspace maps and all the necessary details and contact numbers for German airfields. The listings and format mean that you do not need to speak German to get the info from it. This is a Top Tip Guide for touring Germany.
My own personal recommendations for lovely German airfields with nice restaurants and beautiful scenic surroundings would be:
Dahlemer Binz up in the lovely Eifel region
Altena (EDKD) which is perched 1500 feet up in the hills to the east of Dusseldorf.
Bergneustadt auf dem Dumpel (EDKF) which is another picturesque field to the North East of Cologne.
Koblenz (EDRK) for fantastic views overlooking the Mosel river.
Vilshofen (EDMV)

There are so many more, but hope this sets you off, you can check out all the airfield plates and info on

Have Fun!
