In 2020, renovation work was undertaken on St-Luc’s large bisse which has been recorded since 1593. The start of the route is either at the Achelli parking lot, or the Bella-Tola postal stop. Head for the centre of the village of St-Luc and the church, then follow the signs behind the historical Maison Bourgeoisiale. Take the Tsarirre path for 200 metres and then the Fortoûna road for 400 metres, before turning right and ascending for about 80 metres. From there, let yourself be guided by the peaceful trickling of the water running through the forests, meadows and mayens. On the way back, pass by the Prilet B&B, before crossing the old village of St-Luc and reaching the starting point of your loop.
