From Quimperlé, take the D790 towards Le Faouët. At the Croix Loc Yvi crossroads, turn right towards the village of the same name, then park near the Saint-Diboan Chapel.
(S/E) Walk through the hamlet towards Kerfourcher and, at the bottom of the valley on the left, you will see the consecrated fountain of Saint-Diboan (Sant Tu pe Du) with a converted washhouse enclosing an Iron Age Gallic stele, discovered by chance by a farmer working the adjoining field in the mid-19th century, thus likely confirming the sacred nature of the site prior to the advent of the Christian era.
(1) Take the path opposite the fountain on the right-hand side of the village road. At the confluence of the Loc Yvi and Kerfourcher streams, turn right and continue down towards the River Ellé. You will reach the rocky outcrop known as ‘Lo(ñ)ch Louarn’ (the fox’s lair).
(2) Turn right, follow the Ellé downstream, cross the small wooden bridges provided to help you cross the “frouds” and climb towards Roche Pempic, a rocky promontory overlooking the Ellé: take care, as the path is narrow in places and the drop-off is as steep as a cliff.
(3) Head back down towards the Ruisseau de Pempic, then turn left again towards the Ellé. Follow the river, keeping to the right.
(4) Turn right to begin the climb up onto the plateau towards the hamlet of Kermec, then head left towards “Toull Bahadoù”, a former café-theatre known for its “rixes” (hence the place name), popular with revellers, paper-makers from Kerisole and other farmers returning from Quimperlé.
Turn right onto Rue de Kerluandre, then right again towards Pempic / Loc Yvi. Head straight for the Chapel of Saint-Diboan (S/E).
