From there it runs between the Karwendel range to the east and the Wetterstein range to the west over the Scharnitz pass and the Austria-Germany border to Mittenwald; at the Scharnitz pass it runs for a short distance along the upper reaches of the Isar river. It then bends to the west, running to Garmisch-Partenkirchen between the Wetterstein range to the south and the Ester Mountains to the north.
