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.

Nice to explore the cave. Beautiful spot. After visiting the cave you continue your walk via a very steep descent.
