Here are the new rules to follow: www.kayakslavanne.be/en/kayak-covid-19.
Reservations are required to come: www.kayakslavanne.be/en/booking/.
At the moment the level of the Semois is very low but kayaking is allowed. Sometimes you have to get out of the kayak and pull it. So kayaking becomes more difficult and more tiring.
You can check the water level, day by day: Water level of the Semois
