One of the famous sights in Garmish Partenkirschen is Partnach Gorge (Partnachklamm in German). After the beautiful open views of the mountains, and the green lake, you can cool down between those vertiginous walls.
INFO & PLANNING TIPS - Partnach Gorge
Partnach Gorge is a fascinating place where a tunnel has been carved in one of the wall to allow us to walk all the way up (702 metres (2,303 ft) long) and admire the cliffs that can reach 80 metres (260 ft) high. Walking along this tunnel gives a unique perspective on this narrow gorge.
Looking down you will see the glacier water flowing between those walls and looking up you get small waterfalls on a peak of the green lush forest above.
It is a great destination for a one day excursion from Munich.
