Really very beautiful.

Picturesque Chefna valley. One of those beautiful streams here, originating on the plateau of the Parc Naturel des Sources. The steep drop and rocky bottom make it unique. The water cascades over the boulders in waterfalls and pools. It flows gently now (July), but it will be raging in the rainy season.

The Ninglinspo valley appeals to the imagination of many nature lovers, if only for the name alone. And rightly so, because it is one of the most beautiful areas in the Ardennes in which the most unique mountain river in Belgium flows, the Ninglinspo, a small tributary. of the Amblève. It is a rugged but at the same time breathtakingly beautiful canyon-like environment that is very popular with hikers and nature lovers. This is an extension of the normal walk that also takes you along another river, the Chefna.

The Cascade la Chaudière is a waterfall in Sougné-Remouchamps. The Ninglinspo, a tributary of the Amblève, drops about ten meters there. The waterfall is located in a hiking area, and it is possible to swim in the small lake at the foot of the waterfall.
