By mountain bike

Very hilly circuit, varied terrain and landscapes at the meeting! The first descent is extremely fast... watch out for the pebbles! Due to forestry work on this circuit, we advise you to take advantage of it on the weekend!

After the ascent to Paradise and a ridge route, a descent through the undergrowth with three beautiful hairpin bends.

You will also walk along the Lambertière castle, the Longpra castle and the Servelongue wood.

The +: the multi-hike station, the spot for multi-activities and the picnic break

FIELD NEWS (June 2022): development work on forest tracks on Mont Servelongue. For your safety, do not enter the area if construction sites are in progress. Prefer the weekend!
