Possibility to take a break for a drink or a coffee, or even to have a meal (very good buffet) at the Pit Brasserie of the Spa-Francorchamps circuit (entrance via Ster, just report to the duty security guard in his office). Exceptional panoramic view of the circuit and the pits and paddocks. Cyclists are always welcome.

The Sacrawé raised bog (Plateau des Tailles) is one of the most valuable peatlands in the region. A boardwalk allows visitors to safely cross the delicate bog without damaging the vegetation. It is part of a marked circular trail with information panels and a small viewpoint. As the area is strictly protected, visitors must stay on the marked paths, and individual sections may be temporarily closed. The landscape is characterized by sphagnum mosses, cotton grass, and heathland, and provides habitat for specialized bog plants and animals.

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 Coo waterfall is artificial. Starting from a simple waterfall that appeared in the 15th century, the monks of Stavelot Abbey dug the large waterfall, crossing a meander of the river, to protect the village of Petit-Coo. The fact remains that it is very impressive and at its height of 15 meters is the pride of Belgium.
