During this unique boat trip, we sail on the Brussels-Charleroi canal and experience lockings at the Lembeek lock and the large Ittre lock. Arrived at the foot of the Ronquieres inclined plane, the ship takes its place in a large water basin. In this water tank, we 'track' upwards and bridge a level difference of 68m. In the afternoon, we reach the large Strépy-Thieu ship lift, with which we descend 73 m.
