Halloween Night Trail 2026

If you love it when the forest changes its face as soon as night falls, the Halloween Night Trail in Marchaux-Chaudefontaine is going to be a treat for you 🌙.

Here, in the Doubs, you’re in for a true moment of adventure in Bourgogne-Franche-Comté: trails that smell of humus, tree silhouettes that play with your imagination, and that “Halloween” vibe that puts you right in the mood without going overboard 🎃.

Two formats, two moods: the 10 km if you want to treat yourself and keep some juice for afterwards, or the 18 km if you want to extend the outing and treat yourself to a solid dose of nature in nocturnal mode 🔦.

After the effort, stick around: go breathe in the fresh air in the Chailluz Forest (perfect for an easy recovery), take a detour to Besançon to see the Citadel, or head through the center of Baume-les-Dames on the banks of the Doubs 🍂.
