The Ourthe is born within the natural park

From the east and west, the two Ourthes are born and ride through meadows, along nature reserves or hiking and mountain biking trails. At the confluence, the Ourthe continues its way of meandering meander, lined with deep forests from which emerge remarkable rocky ridges.


Nature's lovers can find, beyond 500 meters high, some gratings cross moors and peat bogs of great biological interest. Extensive open lowlands complete the landscape. In this unspoilt nature, the villages have settled in the valleys and still have a beautiful built heritage.

The logo of the two Ourthes Nature Park reflects different elements of its identity. The twin rivers travel the territory to the confluence; crossing a characteristic relief composed of a succession of hills, deep valleys, dense and steep forests and open landscapes on vast lowlands.


The human presence is added to these elements ... living, tourist, naturalist or simple passerby, each finds its place in this natural and preserved universe. As a little nod to nature, the majestic silhouette of the royal kite, returned after a few years of absence hovers softly in the sky.
