I was OPFOR in Hohenfels but fortunately was able to make an escape to Grafenwoehr as a staff puke. Boonie troops complain about Graf but I really loved being stationed there.
I left in '94 but here it goes…
Unless something has changed, the US Military has a hotel in Garmisch, Bavaria. The area is absolutely breathtaking and there is hiking galore. Same for Berchtesgaden, Bavaria; make sure to visit the Eagle's Nest while you're there.
To my knowledge, sleeping in a tent is prohibited but between the jaegerschnitzels and hefeweizens, you won't feel shortchanged hiking hut to hut in the Bavarian alps. I have more hiking experience near Berchtesgaden (about an hour west of town if memory serves) than Garmisch but you can't go wrong in either location.
Now for some thread drift.
Definitely cross the border and visit/do the tourist thing in Salzburg, Austria when you visit Berchtesgaden.
Prague, Czech is a doable weekend trip from Graf. This was the most beautiful city I've ever visited but I was there shortly after the cold war ended and crime was on the rise. Hopefully the city is as I remembered it.
Make sure you visit Budapest as well. Hungarians may seem harsh at times but I really enjoyed both of my visits there.
Regensburg and Nurnburg are two popular cities for GIs stationed in Graf/Hohenfels to terrorize on the weekends. I think Regensburg is the prettier of the two but I spent more time in Nuremburg since my ex-girlfriend lived there; make sure you catch Nuremburg's Kris Kindle market in the winter. Great place to buy presents and to stay warm drinking gluhwein and eating bratwurst.
Munich for sure and might as well check out Oktoberfest while you're there. We arrived before lunch and were greeted by a very drunk and very naked German who was kind enough to mumble-sing to the hundreds of attendees in that particular tent. Oktoberfest is certainly not for the prude or easily offended but otherwise is not to be missed.
Bavarian crystal is highly sought after and in the '90s, affordable. The exchange rate and currency has since changed so can't say how it is now.
While not necessarily the most high-speed of units I've ever been assigned to, my time in Germany was certainly the most enjoyable of my short career.
