  • Explore and hike in this ancient forest, a UNESCO World Heritage site

  • Learn about the forest, including its ecological, economic and social role.

  • Get a chance to spot some local wildlife.


In the southeast corner of Brussels, running along the line that divides the capital region from Flanders lies the Forêt de Soignes, or Sonian Forest, as it is known in English.

Composed of ancient beech as well as oak trees and teeming with local wildlife, the forest was formally inscribed as a UNESCO World Heritage site in 2017.

The forest is an excellent location in which to hike as well as see much of Belgium’s native flora and fauna. As we pass through well-maintained trails, along lake shores and through thick green foliage, we will get the chance to spot some of the forest’s nearly 40 species of mammals.

Hiking in La Forêt de Soignes for a day is perfect for the ones living in Brussels or the ones travelling in Belgium for a few days and wanting to escape in the outdoor for several hours.

There are tons of different itineraries. I’ll define a program based on the time you have, your wishes and your fitness level. I’ll make sure we have a wonderful hike together.

If we’re lucky, we may even spy the elusive wild boar, which was thought to be extinct from 1957 until its rediscovery in 2007. Roe deer, bats, ducks and frogs are among the various other species of wildlife we may encounter.

There’s nothing quite like a walk in the woods to get the blood pumping and increase your appreciation for nature, so what are you waiting for?

Book me now and join me for both a fun and informative day of hiking through this magnificent forest and learn a little bit about my lovely country!

If you like the look of this trip, then I think you will also enjoy my half-day guided trail run in the Sonian Forest too!

About the Guide


Passionate about trail running, the outdoors and everything that nature provides to us, I got certified as a mountain leader by the Club Alpin Belge. I also work as a school teacher and devote my free time to my artistic pursuits.

Maps are another of my big passions. I collect them and spend hours looking at them and searching for the best itineraries in the Alps, the Andes, the Carpathians...and then I take you to explore them, running or walking.

My mission is to share with you the happiness that a high altitude lake can provide, the comfort that one can find in a rustic mountain hut and the excitement of walking along a mountain ridge. Looking forward to meeting you!

Il y a juste deux petites semaines, j\'ai participé à un weekend rando Trek Atout... Un superbe weekend ! Ok, la météo nous a fait un super cadeau : de la belle neige sur nos Fagnes! Mais tout de même, sans le \"président\" rien n\'aurait été pareil ! Nous avons été accueillis comme des amis, Thibault nous a emmené sur des petits chemins et sentiers magnifiques, nous avons appris à jouer au whist, nous avons partagé l\'apéro, Thibault nous a préparé une (demi)soupe sur un sol enneigé, nous avons échangé et beaucoup rigolé ! Je pourrais encore allonger la liste pour les non convaincus! ... Merci encore Trek Atout! (Depuis, je m\'entraîne encore plus à la course à pied en espérant un jour faire un trail avec TrekAtout).
