Check out the location

Surrounded by nature

Les Ondes is located in the picturesque Walloon village of Nadrin, part of Houffalize municipality. Les Ondes belongs to a family of ancient woodlands, Wallonia’s Natural Heritage – Le Hérou – and the Ourthe River. We revere nature, treating it with tenderness. Beavers here have room to build dams and the food forest burgeons with fruit trees and herbal plants. Nature is our companion and home. And that’s a feeling we’re eager to share with you during your stay at Les Ondes.

Explore the surroundings

Test your limits

Les Ondes is all about the power of nature. You’ll experience that on your own and as part of the group. We set up all kinds of activities to test your limits, e.g. rappelling from the rocky Le Hérou spur, a trip down the rushing river, or a bivouac in the woods. It’s the perfect environment for creative team tasks and personal development. But experiencing the natural world? That’s always at the heart of what we do.

Testimonials

Les Ondes is a green oasis in the Belgian Ardennes. It’s the perfect location, with fun activities nearby. Guests really do come first here. I’ve been before, and I’ll definitely be back.

Deborah Verschoor, docent Hotelschool The Hague

“Les Ondes voelt telkens weer een beetje als thuiskomen. Het huis omarmt je met nostalgie én modern comfort en de tuin nodigt uit om te vertragen, samen te genieten en te focussen op wat er écht toe doet. De omgeving van Nadrin geeft opties genoeg om te wandelen, fietsen, het water op of in, … om na al die actie te kunnen ontspannen in Les Ondes in de hot tub, sauna of rond het kampvuur. ...

Cathy Mostmans, Leadership Coach & Trainer

The Les Ondes Team are masters of hospitality. Meeting them on arrival feels like a hug from an old friend. Everything is exactly as it should be. And with all the gorgeous hiking trails, it’s the perfect base for Infinite Walk.

Les Ondes is the place to be for a fun weekend with a group or family. The grounds are gorgeous and equipped with everything you need. We booked a follow-up weekend pretty much instantly. That says it all, right?

By now, Les Ondes feels like coming home. Every year, we get the chance to enhance Noeste’s teamwork in a relaxed, friendly setting. Sam Steen, Managing Partner at Noest Les Ondes always feels a little bit like coming back home. It’s where you come to unwind. At the same time, nature here gives you the boost you need to get going again.
