A delightful path in the Ruisseau du Blanc Gravier valley. It alternates between a forest path and a stream. It connects the pond with the Quartier Blanc Gravier.

Unexpected spot in the middle of the park, next to a viewpoint over the city (let's see if we can still see that far when the trees have turned green...), a reminder of a time when the walking routes were punctuated by https://www.dogwhistlings.com

Walking path in deciduous forest that becomes more hollow and beautiful as you descend. You may be accompanied by a stream in the wet season.

One of the many beautiful views of the Ourthe, here marked with graffiti paint. Very well visible from the E25 on the right side when you descend to Liège. Driven past and looked at it 100s of times. So, I was here know :-)

The Rochers du Bout du Monde are a natural curiosity of certain geological interest, also classified by the Royal Commission of Monuments and Sites. Located on the right bank of the Ourthe, 7 kilometers south of the city of Liège, from their height of 80 meters they dominate an old meander of the river, the course of which was modified during the construction of the E25 motorway in mid-1970s. Emerging from the Bois d'Embourg, this imposing massif is made up of shelly limestone banks inclined 40 to 45 degrees towards the south. Botanically, it is one of the northernmost xerothermal stations in Wallonia. Calcicolous plants such as the horseshoe grass (Hippocrepis comosa), the mountain libanotis (Seseli libanotis) or the bluish sesleria (Sesleria caerulea) in fact reach the northern limit of their regional area. The exposed rocks also host interesting communities of lichens. Among the fauna, it is worth highlighting the presence of a large population of wall lizards (Podarcis muralis), a rich population of snails and several species of unusual diurnal butterflies. Unfortunately, part of the rocks is gradually being colonized by the invasive false Japanese varnish (Ailanthus altissima), threatening the sustainability of the rock groups. Most of the forest slope including the Rochers du Bout du Monde is registered with the Natura 2000 network in site BE33014 - Vallée de l'Ourthe between Comblain-au-Pont and Angleur.

Small vertical limestone rock. The cave was inhabited in prehistoric times. There is a path leading there that can be very slippery in rainy weather.

Exceptional view but beware, caution is required because access is difficult and quite dangerous in the sense that there are no railings.. For the less adventurous, the viewpoint located further to the left, a few tens of meters, is to be preferred.
