Trôs Marets Waterfall

Highlight • Waterfall

Certainly a waterfall after a thunderstorm or after the snow has melted. Usually just a cascade in summer, but still a photo highlight.

Hoëgne River

Highlight • River

The Hoëgne is the most important tributary of the Weser and has its source on the Venn plateau near Baraque Michel. The valley of the Hoëgne is of remarkable botanical interest, not only because of the liverworts, mosses and ferns that grow there, but also because of its floral richness.

The trail was laid out at the end of the 19th century and inaugurated by Queen Marie-Henriette. As you walk, you will discover the centenary footbridge "Le Centenaire", a section of the Hoëgne that becomes a torrent as far as Belleheid and two waterfalls along the river that bear the names of King Leopold II and his wife... (marked path No. 55).

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.

The earliest mention of the town of Coo, under the Latin form “collo”, dates back to 1307. A mill, whose existence is documented from 1483, was fed by the water of the Amel. It is very likely that the monks of Stavelot Abbey created a meander along the river to feed the mill and not to create a waterfall, but it is likely that the water sometimes had to overflow and spread over the nearby rocks … Source: http://tourismestavelot.be/de/wasserfall-von-coo
