Ascent
The hike starts from the little chapel of Kappel in Unterammergau, where you can park your car. From there you immediately turn left and follow the flat countryside road. After twenty minutes you will reach a junction, where you should turn right following the indications for Hörnlehütte. The road will start to climb, till becoming a trail in the forest. The trail eventually ends up at the Zeitberg, where the Hörnlehütte hut is located and you have wonderful views of the surrounding Alps.
Leaving Zeitberg, you start to climb the three horns (the Vordes, the Mittleres and the Hinteres Hörnle). After having enjoyed the views from the top of the Hinteres Hörnle, the descent begins.
Descent
From the Hinteres Hörnle you continue down following the trail to the Drei Marketen junction. Once there you take back the forest way, following the indications back to Kappel.
