Ruisseau de Soumiée

Highlight (Segment) • River

For one and a half kilometers you follow the Ruiseau de Soumiée ... which plays with your feet. We went there at the end of March and wearing waterproof high shoes (bottoms) kept your feet dry.

What is the best time of year to hike this loop?

The trail offers picturesque views year-round. However, due to its challenging and often muddy terrain, it's best enjoyed during drier periods, typically from late spring to early autumn. Wet weather can significantly increase the difficulty and slipperiness of the paths, especially in sections requiring scrambling or rope assistance.

Is this trail suitable for families or beginner hikers?

This trail is generally not recommended for families with young children or beginner hikers. Its 'moderate' to 'hard' difficulty rating, combined with steep slopes, muddy conditions, scrambling sections, and even rope-assisted parts, makes it more suitable for experienced hikers with good fitness and sure-footedness.

What gear and footwear are recommended for this hike?

Given the rugged and challenging terrain, sturdy hiking boots with good ankle support and grip are essential. Consider bringing hiking poles for stability on slippery or steep sections. Due to the potential for scrambling and rope assistance, gloves might also be beneficial. Always carry enough water and snacks, and be prepared for changing weather conditions.

Trail Reviews

Stijn
July 10, 2022, De wilde vallei van de Hermeton

This walk starts on the beautiful footpath on the banks of the Hermeton. Sometimes quite diagonally on the rock wall and regularly you have to go up steeply (there are rising ropes) because the path comes to a dead end. Then you climb out of the valley through the woods and descend back into the valley of the Ruisseau de Soumiée, a stream that joins a trail that you follow and often flows over the road. In this way we systematically climb back up and then you slowly descend back to your starting point, the village of Hermeton-sur-Meuse. Highly recommended!

How much fun can walking be? 🤩🚶🚶‍♀️ On this Easter day we left the Tour of Flanders for what it is and went to the Hermeton again. After last week's middle course, the lower course was now on the program. The middle course already appealed to us, so we drove to Hermetton-sur-Meuse in good spirits. Once again, this walk can be found on the site www.originelewandelingen.be, but for the written guide you have to pay a fee for a selection of "adventure walks". We already did that a few years ago. But the title "adventure walks" made us look forward to the walk even more. And once again it was a fun, beautiful, somewhat adventurous walk. Not that it was dangerous, but there are some passages where you have to go up and down using ropes to avoid a rock. When you follow the Soumiée much later, it becomes adventurous again. simply because you risk wet feet. You have to cross the Soumiée several times, which crosses the road at different times. Even though we are still early in the season, we didn't get our feet wet, but you can test here whether your shoes (bottoms) are waterproof. Just like last time, the course of the Hermeton is pure, untouched nature because humans simply cannot handle it. Not with machines anyway, luckily it worked with some ropes. One of the most beautiful walks we have undertaken. 🤩🤩🤩🤩🤩 For the collection: https://www.komoot.com/nl-nl/collection/1212328/-originele-wandelingen
