The Mill of Altwies


One of the emblematic places of the Moulin d'Altwies is its adventure park. The latter is a large course in the trees with many ropes and platforms guaranteeing fun and variety for both adults and small adventurers.


Le Moulin has a unique route in the region: Le Duo Parcours. The latter helps to strengthen team cohesion because it is only done in pairs and therefore, it strengthens the bonds with your teammate. To finish on the hats of wheels, take a seat at our famous 250m zip line which offers a magnificent view of the terrain during the descent.

Another strong point of the Moulin is the Eurotrack, a 12-meter-high ramp which culminates at a 42 ° incline. The latter is crossed on four wheels offering thrills guaranteed.

In addition to this, you need to know more about it.
