At approximately 37 meters, the top of the Anticline, also known as the Homalius Rock and especially the Falize Rock, is literally the highest point in Durbuy. It has been a highlight for many visitors for years, thanks in part to the surroundings and beautiful water features. The rock is somewhat older than the average visitor. It's said to be more than 300 million years old. However, the rock layers are much older: around 375 million years old. The name Anticline comes from the geological phenomenon known as an anticline. It's the opposite of a syncline. While the former is a fold formed over many years, with the innermost layers being the oldest and the folds running downwards, synclines have folds running downwards. Such folds can form for various reasons and range from very small to large, as seen here. Originally, everything was, of course, horizontal. The inverted U-shape created by uplift in Durbuy is not only beautiful to see but also special. And Durbuy has beautifully highlighted this. Another beautiful anticline can be found in Han-sur-Lesse, also in the Famenne-Ardenne region, albeit in the province of Namur (here we are in Luxembourg), where it has been given the name "Tête de bouc" (Tick of the Rock). There's a waterfall and a large water feature at the end of the expansive pond in front of the rock, which you can also climb. And everywhere there's space to admire it all while sitting and relaxing—or enjoying the water. Don't forget the many smaller works of art and curiosities, and take a look in the water.

Built in the Middle Ages, only the keep and a few architectural elements remain from that period. After its partial destruction in the mid-17th century, it was restored and transformed into an elegant pleasure palace. The French-style park and gardens, redesigned in the 19th century, are part of the Parks and Gardens of Wallonia, designated as an exceptional cultural heritage site. They are free to enter during the castle's opening hours. Magnificent rose beds adorn the grounds. To learn more about the park and its grounds, you can download audio guides at https://www.modave-castle.be/les_jardins.

Roughly 20 routes on the main rock and a good handful further to the left - all between 4 and 6b+, although the mix is quite good.

A must-see is this steep part of the Ourthe Valley, bucolic and ideal for climbing, as well as the memory of Charles Quint in the ruins of the Lognes castle! Hiking there is a varied pleasure between the relaxing banks of the river where fishermen and kayakers compete, and the impressive rocks to be bypassed by steep paths. Go hiking there, fun is guaranteed!

Impressive natural phenomenon. Exposed in the old bed of the Ourthe. On the town square there is still a small anticline visible on which the castle is partly built.

Beautiful geological phenomenon that the Ourthe literally brought above water here. The origin of this earth movement must be more than 350 million years ago. Fascinating
