Best Hikes in Belgium: Ardennes, High Fens & More

Belgium offers a surprising variety of hiking opportunities, blending lush forests, dramatic river valleys, rolling hills, and historic landmarks. From the rugged Ardennes in the south to the expansive heathlands in the north, these trails cater to beginners and seasoned trekkers alike. Whether you’re seeking serene nature walks or challenging ascents with panoramic views, Belgium’s paths deliver rewarding experiences year-round.

Why Hike in Belgium?

The country’s compact size makes it ideal for hikers, with well-marked trails accessible from major cities like Brussels. The Ardennes region dominates with its dense woodlands and waterways, while Flanders provides flatter, heath-covered routes. Expect diverse terrain: cascading streams, ancient castles, WWII remnants, and wildlife-rich moors. Trails are maintained by organizations like Nature and Forest in Flanders and regional syndicates in Wallonia, ensuring safety and signage.

Hiking here is enhanced by seasonal beauty—autumn foliage in the south or spring wildflowers in the north. Public transport connects many starting points, and nearby villages offer cozy accommodations and local cuisine like hearty stews or fresh waffles.

Iconic Trails in the Ardennes Region

The Ardennes, Belgium’s southern heartland, boasts some of Europe’s most picturesque hikes. This area features steep valleys, roaring rivers, and mist-shrouded forests.

Tros Marets Valley Exploration

This medium-difficulty trail winds through a verdant valley near Malmedy, showcasing diverse landscapes from meadows to rocky outcrops. Spanning 8 km, it starts at Ferme Libert and rewards with tranquil streams and wildlife sightings. Allow 3-4 hours, with some elevation for a moderate challenge. Ideal for photographers capturing golden-hour light filtering through trees.

Ninglinspo River Adventure

Follow the Ninglinspo stream on an easy 7 km loop near Aywaille, famous for its pebble-lined pools and small cascades. The path hugs the water, offering chances to cool off in summer. It’s family-friendly but can be slippery after rain—wear sturdy shoes. Highlights include serene glades perfect for picnics.

Hoëgne River Promenade

A network of trails along the Hoëgne River provides options from 2.5 km strolls to 21 km epics, all featuring mini-waterfalls and mossy boulders. The classic 10 km route from Promenade de la Hoëgne is easy-moderate, taking 3-4 hours. Pine-scented air and bird calls make it a sensory delight.

Waterfalls and Castle Circuit

This ambitious 19 km hike links two major waterfalls, viewpoints, and Reinhardstein Castle. Taking 5-6 hours, it traverses the High Fens with boardwalks over peat bogs. Moderate difficulty due to length and some steep sections; pack water and snacks. Stunning in autumn with fiery colors.

High Fens and Eastern Highlands

Belgium’s highest point, Signal de Botrange (694m), anchors the High Fens nature reserve. These moorlands offer vast, open vistas unlike the forested Ardennes.

Baraque Michel and Botrange Traverse
