Nature, Sports, Tours Bike-Club Tour through the valley of Nagold 9. May 2013 Herbert Started the tour via Ehningen, Aidlingen, 7-Tannen and past Holzbronn into the Nagold-valley, then return “up” out of the valley at Iselshausen (Picture). Now I’ll see how I return home, probably via Mötzingen and Öschelbronn and Herrenberg.
