Todays hike we did near Calw, in the Northern Black Forest. The hike was 14 km, 4 hours, 380 meter high difference. The majority of the hike lead over forest roads, after the half hike we took turns into smaller paths in order to get some trail feeling. The trails that been included into the hike lead to the Gimpelstein (rock formation), Rötelbachtal (River Valley) and the Stubenfelsen (rock formation). In generally the hike is recommendable, unfortunately you can see the over-tourism in the Black Forest at the moment. As many Germans are doing vacation at home. We saw at the camping/fire places a lot of rubbish including empty bottles, beer cans, tissues etc. This is really sad, Germans we can do better than that! It is fine to have a good time in nature, but leave no trace. Take everything back home again.
