From the parking in Lenggries follow the street until you reach via the grassland the Tratenbach. Cross it and follow up the forest road until the cozy Denkalm. From there you have a nice panorma view of Lenggries and the Brauneck on the other side. The Alm is worth going to also in bad weather, it lays westwards and offers you a long sunset. If snowy you can sledge down. Otherwise turn right at the Tratenbachbridge and follow the stream until the youth hostel of Lenggries. Take the Leitenweg and Bachmairsgasse to get back to your starting point.
