View of the High Fens Plateau

Highlight • Viewpoint

The "Hohe Venn" is a high moor with such special flora and fauna, that here everything is under nature protection. It is Belgium's largest nature reserve.

The landscape here is very open and overgrown with typical moorland plants. I have not tried it, but I'm pretty sure you would immediately sink knee deep into the mud as soon as you leave one of the trails. The view up here definitely makes for "wow" moments.

Olef Reservoir

Highlight • Lake

The Oleftalsperre was built in 1954-59. Due to cracks, the barrier had to be reinforced twice afterwards. Since 1965, the barrier has been used for drinking water, energy production and water level regulation for the Olef.

The height of the dam wall above the valley floor is 54.6 m, the storage capacity of the lake 19.3 million cubic meters.

High Fens

Highlight • Natural

A unique heather landscape heralds the High Fens, which one passes on this section. The fascinating high moor area is a gigantic water reservoir, so that there are numerous streams and rivers to be bridged on this section. Past the former station building of Sourbrodt, the Vennbahntrasse paves its way between the two lakes of Robertville and Bütgenbach and finally ends in Waimes (Weismes).
