On the Panoramaweg to Burgruine Altes Schloss

Today is cloudy after a rainy night, so I left my hostel at 8:30am, planning to hike in the forest until mid afternoon, then treat myself to 4 hours at the Friedsrichbad.
It seemed a bit lame just to go back into town and go to the spa without actually doing something strenuous.
I found this landmark Gruner Stein easily enough after hiking up past a spring called Bernardus Brunnen, where I saw 2 different people drive up to fill some plastic water jugs.
