Ulm - Firedrichshafen (Bodensee)

up to Bad Waldsee Donau-Bodensee cycleroute. Be careful in Dellmensingen: here the sign is missing after turning from Langen Straße into Werdensteinstraße, which should guide you immediately left into Wasserturmweg. Moreover, in Ochsenhausen on Schloßstraße (at the height of the end of the monastery): here the sign points left into the forest path, which can drain the last strength from your legs. Actually, the main route goes along the road to Rottum and I recommend that too! In the forest between Graben and Osterhofen, the main route actually goes left up a gravel ascent through the woods, which you can save by just going straight (the green and white cycling sign to Waldsee even points in that direction). From Bad Waldsee we were fed up with the Do-Bo-Radweg and only rode on the road, meaning no more searching for the often washed-out blue signs, just asphalt and above all no unnecessary kilometers and height meters any longer.
