Great view of Königssee from the Jenner summit
Your starting point is the Explorer Hotel Berchtesgaden. From there, hike towards the Jenner until you reach the Hinterbrand parking lot.
You hike along a wooded path towards the Jennerbahn mid-station. Follow the forest road signposted to the Königsbachalm.
When you reach the junction at the Wasserfall-Alm, keep left. Then follow the path to the Mitterkaseralm. From there, the path winds up to the Jennerbahn mountain station.
Almost there
From the mountain station, it's about 15 minutes to the summit. From here, the path climbs gently to the viewing platform. The effort is definitely worth it, as the view from the top of Lake Königssee, about 1,200 meters below, and the east face of the Watzmann are simply breathtaking.
If you can tear yourself away from the magnificent view, you can return to the valley the same way. There are several places to stop for a break along the way :)
