Depends greatly on the season and how long you have, but for a few tips:

Munich: Cool little artist district with a boat railway bridge - https://maps.app.goo.gl/13Zjw2usCbvcsr1UA

Inner city surf wave with a great spectating spot - https://maps.app.goo.gl/Ha1EQBvRoG1dLoyw5

South of Munich:

Murnau is a beautiful town with great views of the alps, reachable via train, and there is a great resteraunt near protected wetlands I can recccommend - https://maps.app.goo.gl/m9317uf5j7qKw8ML6

Cheimsee is also beautiful, little islands with a castle on a lake and a beergarden - https://maps.app.goo.gl/ZbxWRT7cDh66nzbS7

Further into the Alps you can find Königsee which is stunning, has great hiking, and plenty of history - https://maps.app.goo.gl/6fXAN1KwP8PqmTHc7

If you're into snowsports then now is a great time to get into the mountains and rent some gear to have a fun day. For hiking it is probably better to wait for the snow to thaw and then do a hut to hut treck if you can.

As a note, I do not reccommend going to see the Disneyland Castle, a.k.a. Neuschwanstein. It'll involve lots of crowds, a rushed tour, and a mediocre experience overall.

Enjoy!
