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 10.5%.
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).
