The trip across the bottom of Belgium, the Nimy-Blanton-Perrones, Centre and Charleroi-Brussels canals, and the River Sambre are pretty much pass-through territory; just not very exciting.
Occasionally there is what some people (like us) find interesting. At the junction of the Brussels-Charleroi Canal and the River Sambre, the waterway passes through a working steel plant. I think the guide books would call this "an industrial outlook."
There's also a long section where the walls of whaterever plant is on the other side have been covered with some really interesting art.
By just about lunchtime on Sunday we were tied up on the city quay wall in Namur. We'd reached the Meuse and even the air smelled French!
