The peat bogs are between 7,000 and 10,000 years old, having formed immediately following the last glacial retreat.
The Signal de Botrange is topped by a 24-meter-high stone tower built in 1923 to allow visitors to reach the 700-meter elevation mark.
The park experiences a unique 'micro-climate' that results in snow cover lasting significantly longer here than in the rest of Belgium.
The High Fens act as a natural water reservoir, contributing to the high water quality of the surrounding river catchments.
Certain areas of the park are designated as 'Zone C' and are completely off-limits to visitors to protect nesting grounds of endangered birds.
The soil acidity is so high that it prevents the decomposition of plant matter, leading to the preservation of organic materials for millennia.
The High Fens-Eifel Nature Park is a transboundary protected area spanning the border of Belgium and Germany, characterized by its unique raised bogs and heathlands. It contains the highest point in Belgium, the Signal de Botrange, reaching an elevation of 694 meters above sea level. The park protects rare flora such as the round-leaved sundew and the bog rosemary, which thrive in its acidic, waterlogged soil. Large sections of the plateau are strictly protected nature reserves where human access is restricted to designated boardwalks. The landscape was formed during the last ice age, leaving behind vast peat layers that continue to accumulate slowly today. It serves as a significant hydrological sponge, feeding numerous regional rivers including the Vesdre and the Warche. The park's climate is notoriously harsh, featuring higher precipitation and lower temperatures than surrounding lowland regions. Visitors can explore various wooden walkways designed to prevent erosion of the fragile bog ecosystem. The area is also a habitat for diverse wildlife, including red deer, wild boar, and the rare black grouse.
The raised wooden boardwalks during the 'golden hour' or when low-lying mist creates a dramatic atmosphere over the heather.
Always stay strictly on the wooden boardwalks; the surrounding moorland is fragile and potentially hazardous to walk on.
Bring multiple layers of clothing, as weather conditions on the plateau can change rapidly from sun to heavy mist or rain.
Check the park's color-coded fire and access status boards before entering, as some zones close during high fire risk periods.
Attempting to walk off-path onto the spongy moorland, which is both prohibited and dangerous due to deep, unseen peat bogs.
Some trails are subject to seasonal closures for wildfire protection; always consult the dynamic access map provided at the Nature Centre.
Dogs must be kept on a short leash at all times to protect wildlife; picking plants or disturbing wildlife is strictly prohibited; stay on marked paths.
