La Pierre Saint-Martin N°15 – Facile 2h30-7km

Departing from the Serre forest house, located 1 km after the hamlet of Dourbes, this walk runs along the foot of the imposing Dourbes bar and passes by the Pierre de Saint Martin. Legend has it that it bears the footprints of St Martin, who to flee the devil had crossed the bar by clearing a passage and thus created the hole of St Martin.
