Under normal circumstances and during floods | In case of dryness | When in doubt
Dinant Evasion does its best for that your kayak trip down the river Lesse takes place in optimum conditions. However, the river Lesse is vivid and changeable...all year round.
It is each's responsability to inquire about sailing conditions on the river Lesse, which can change very quickly in only just a few hours. If rain is very intense, the level of the water can sometimes vary from 10 to 20 cm in 12 hours time.
Seek advice before, whatever the season !
In the morning, before heading off, verify the level of the water by visiting our reference website of the Walloon Region :
