The climb to Büchereck from the Gutachtal is a short, steep climb mainly through forests. The climb starts at the beginning of road L107, south of Gutach. Soon a road sign announces that the slope will be 18% but this is a strong exaggeration. The steepness that I measured over intervals of 250 m does not exceed 12%. After the relatively easy first few hundred meters (7%), the road steepens to approximately 10%. Over the next 3 kilometers the mean slope (8%) is not extreme but since a few parts are definitely steeper, climbing is harder than those 8% suggest. The final kilometer has a more gentle slope (5%). Views are rare with the exception of the first and the final few hundred meters. Road conditions were excellent when I made the climb (2014).
