Valley of the Semois

During this three-day guided bikepackingtrip you will discover the Semois valley in the French Ardennes. Steep rocky slopes and wide forests along the winding Semois form the ideal decor for exploring with a packed mountainbike. Would you like a little more luxury? Discover the new option 'Overnight stay in a tree house'.

During this bikepackingweekend "Valley of the Semois" you will experience the beautiful surroundings of the valley. You will explore it by mountainbike along with al the necessary equipment such as sleeping equipment, food and water. This allows us to travel independent for a few days, away from busy society, to fully enjoy the nature and the adventure.

This trip has a total of 72 kilometers spread over two daytrips. You will be self-sufficient for eating, drinking and sleeping outside. We will give you all the advice you need to do this properly. There is no need to buy special bikepacking bags because you can rent them from us at a low price.

New option!

Would you like a little more luxury and less luggage on your mountain bike? Then choose the option “Overnight stay in tree house”. You spend the night in one of the two fairytale tree houses along the banks of the Semois. The tree houses are equipped with a wood stove, a cozy warm evening is granted!

Two weeks before the start of the trip, Trailgrip organizes an information evening. At the moment we are handing out a lot of tips, you will receive an detailed briefing and we will deliver your bikepacking bags if you have chosen to rent them.


Monthermé - Roc La Tour | 40 km

When the bikes our ready we leave the small port of Monthermé taking the bridge over the Meuse. A short but steep climb takes us out of the valley while the beautiful rock massif "Roc La Tour" appears in the distance. Enjoying a short downhill, we arrive in "La Roche Aux Corpias" where our route crosses the Semois and climbs to "Point de Vue du Liry". Here waits us a great view of the Semois, which winds its way through the countryside and the village of Tournavaux.

Winding paths between the many deciduous trees in this area lead us to the next viewpoint "Col du Loup ". We descend on a challenging single track towards Nohan Sur Semois. This idyllic place is the ideal opportunity for a picnic. After replenishing the water supply, we cross the Semois again over an old pedestrian bridge in the village of Naux. This bridge is gratefully commemorated as the only bridge in the region that was not blown up during the second world war.

We climb out of the valley and stretch our legs at the old forest house "Le Champ-Bernard". After a few more easy kilometers we end this day at "Roc La Tour". A cozy campfire, an unforgettable view and a drink are the ideal setting to enjoy this hard but beautiful day.

If you choose the option "Overnight stay in a treehouse", after "Roc La Tour" you will descend six kilometers to the banks of the Semois. This brings the daily total of this option to 46 kilometers.


Roc La Tour - Monthermé | 32 km

Strengthened by a powerful breakfast, we leave the Semois behind and head into the deep deciduous forest. If you have opted for an overnight stay in a tree house then the day starts with a climb towards "Roc La Tour" which brings the daily total to 38 kilometers.

The morning is characterized by the many forest paths that lead us along drinking fountains and lots of natural beauty. In the small village Les Vieux Moulins D'hargnies we stop for a picnic. In "Auberge Le Balcon en Forêt", a drink gives us the necessary energy to resume our tour in the afternoon.

A final climb takes us to "La longue Roche" a viewpoint on the spectacular meander of the Meuse around the town of Monthermé. We end our adventure with a technical downhill towards the small port of Monthermé. But we will not say goodbye before one last drink on this unforgettable adventure!

Start and endpoint

Starting- and ending point of this trip is at the small marina beneath the bridge of Montherme. We choose this place for different reasons. You can leave your car at the free parking space. If you travel by train, the trainstation is only 3 kilometers away.


Adventure and nature share a first place on Trailgrip travels. So don't expect a luxurious bed, but relax on a campfire and a warm sleeping bag. Spending the night in a treehouse with stove is also an option we offer.

Trailgrip provides a few tarps for this trip. These are waterproof sails that protect us against wind and light rain. The tarps are tensioned between our bikes or trees. This allows us to camp as true adventurers under the starry sky.

In case of bad weather conditions or on request of the participants, there is the option of giving preference to a campsite at each end point. These accommodations are not included in the price of this weekend.
