best way really is to come out of your place and turn left...towards
Englischer Garten... over leopold to ohm str. Cut thru 'til you reach the chinese tower and at the back of that keep heading east 'til you reach the Max Josef Brucke. Turn right before you go over the bridge and keep going until you hit the deutche museum.
From there you can cut over the river and keep going up-stream 'til you reach where we met for the trail stuff. (Marien Klause) At the back of that (facing away from the river) there is a steep climb up the hill to a tarmac-cycle path. Right turn on that and that will head you in the direction of
Grünwald. Or Bad Tölz or Tegernsee or Italy. Depending on how frisky you are feeling.
