A fisherman can also indulge in this region. Along the Semois itself you will find several quiet places full of fish. To fish in the river you do need a fishing license, which you can get at the fish shop in Vresse. In Mouzaive (a part of Vresse) you will also find a trout fishing well, you can go here without a license but you will have to have your own fishing gear.
For specific culture & sports activities in the area, we kindly refer you to the website of the tourist office (office located in Vresse itself):
