By traveling together, we believe we can do more than just explore - we can help amplify new voices, create lasting connections, and foster a more meaningful kind of adventure.

🚂 Steam Train Adventure in Wallonia | Mariembourg → Treignes Festival
Kraainem Metro, Brussels, BEJoin Sunday Vacations for a different kind of day out in Wallonia: historic steam locomotives, countryside views, railway heritage, a lively festival atmosphere and a group of international people to experience it with.
We’re heading to Mariembourg for the Festival Vapeur 2026, organised by the Chemin de Fer à Vapeur des 3 Vallées (CFV3V).
## 🌿 Experience overview
For one weekend, the historic railway between Mariembourg and Treignes comes alive for one of Belgium’s special railway events.
Four historic locomotives - SACM, BR-64, AD09 and ELNA - are announced for the festival, alongside musical entertainment, railway modelling, food options, an artisan market in Treignes and other activities.
But you definitely don't need to be a train enthusiast.
For us, this is about slowing down, discovering a lesser-known corner of Belgium and sharing an unusual experience with new people.
Come solo, bring a friend, meet the group — and enjoy the ride. 🌿
