I was stationed with the Army in that part of Germany (it was West Germany at the time) in the late 80s. I’ve traveled back several times since then.
There’s nothing golf noteworthy.
I would do non-golf sightseeing. You’re close to Salzburg. Also Herren Chimsee Castle. And Munich. And Berchtesgaden. You also might luck out and find a local town beer fest which I always preferred over the more commercial venues in Munich.
If you’re intent on playing golf, and don’t mind a 2 hr drive, Club Augsburg, just south of Augsburg, was Bernhard Langer’s home course. There’s nothing special about it (I played it once).
Another course I think is OK but would be about 90 minute drive is Feldafing
https://www.top100golfcourses.com/golf-course/feldafing Back in the 80s, there was a hard rumor that American service members could play Feldafing for 8 DMs because Eisenhower set the rate in perpetuity when he was NATO commander in the 1940s. I never put this theory to test but looking over the website it’s not bad and it has wonderful lake views. Also, Andechs Monastery (and brewery) is close by.
