Stavelot Tourist Traps

All the business around the Coo Waterfall is so pathetic. The waterfall itself is relatively impressive but nothing exceptional.
However it is generating many different touristic activities. The karting or the kayak rental could make sense but some other are more discussable.
For example, what is this ski-lift doing there? What about this fake Manneken P!ss where you have to insert coins to see it pee (a real trap btw)?
The worst thing is the souvenir shops, they are really selling anything, nothing related to the local artwork or culture but craps going from the Heavy Metal T-shirt to Egyptian artifacts.

Unique Suggestions: Walk around in the countryside...
