The official climb begins on a concrete and rather flat surface. Suddenly, the forest appears, interspersed with cobblestones; that's where the real climb begins.

The Deux-Acren lock is the last one before the Dender River enters Flanders. After both Geraardsbergen and the upstream Walloon village of Deux-Acren were hit by a devastating flood in 2010 (which even claimed one life), plans were drawn up to carry out flood protection works on the Dender. Progress in Wallonia progressed faster than in Flanders: the dam works in Deux-Acren were completed in 2017.
