Often referred to as the “Hyon waterfall,” this waterfall near Mons intrigues visitors with its natural appearance. However, contrary to what its name suggests, it is not a natural waterfall, but rather a waterfall linked to a hydraulic structure built on the Hyon stream.

A waterfall created by a hydraulic structure
The waterfall visible today was formed by a weir or small dam, originally designed to regulate water flow. Over time, vegetation and erosion have given it a more natural appearance, which is why the site is often mistaken for a real waterfall.
This type of development is common in Belgium, where the moderate relief rarely allows for the formation of marked natural waterfalls.
Why do we still refer to it as a “waterfall”?
The term “Hyon waterfall” is primarily a common name. Locally, the waterfall is known by this name because of its visual appearance and the sound of the water pouring over it, reminiscent of a small waterfall.
This discrepancy between the popular name and the technical reality makes it an interesting curiosity to discover.
A quiet, green spot near Mons
Located just a few minutes from Mons, the Hyon waterfall is set in relatively green surroundings. The banks of the stream and the surrounding paths provide a pleasant setting for a short walk.
This is not a developed tourist site, but rather a discreet place, appreciated by locals and curious visitors looking for little-known spots.
A place to observe with respect
As this is a hydraulic structure and not a protected natural site, it is important to remain cautious and respectful. The site has no specific infrastructure and can be slippery in wet weather.
Keeping the site quiet and clean will help preserve this unusual little corner in its current state.
