From Vaison-la-Romaine, head towards Roaix via the D977 and, after about 3 km, park your car on the right-hand side on the lay-by just past the hotel “La Bastide de Vaison”
(S/E) Take the dirt track, turning your back on the D977, to join the small tarmac road.
Join the road on the left – a former railway line – and follow it for about 1 km through fields and vineyards, passing the hamlet of Saint Estéve on your right.
(1) After a copse, turn left onto the path running alongside the field which follows the Sausses ravine to join the D977 departmental road.
(2) Follow it to the right for about 500 metres, then cross over to join theGR®®4(marked with red and white signs).
(3) Turn left onto theGR®® towards the hamlet of Saint Just; walk past it until you reach a three-way junction.
(4) Take theGR®® to the right towards the chapel and leave theGRP®® (yellow and red markings) on your left. Turn right, following the markings, and cross the Bois de Darboux. Join a dirt track and follow it to the left.
(5) Leave the track and turn right, cross the stream known as the Rieu (take care – it’s a narrow grassy path) towards Mont Vert to reach a dirt track. Follow it to the left until the next junction, staying on theGR®®.
(6) At the junction, turn left to climb through the forest, still following theGR®® for about 1 km. Then turn left and leave theGR®®4to follow a localGR®® trail (marked in yellow and red) towards the Notre-Dame d’Aubusson Chapel.
(7) Continue along theGRP®® to the right, heading up a steep climb to the chapel.
(8) Head back down via the small path through the woods behind the chapel, then leave the woods and walk along a track bordering the vineyards to rejoin theGR®® de Pays and a tarmac road.
(9) Follow the tarmac road to the right towards Séguret, through fields and vineyards for 800 metres until you reach the second junction.
(10) Turn left towards “Derrière le Château”, a path that is half dirt track, half tarmac, still following the GRP®®.
(11) On reaching the hamlet of Derrière le Château, turn right to climb, first along the edge of the vineyards and then very quickly into the woods, until you reach the keep overlooking the village of Séguret.
(12) After exploring the area, head back down to Séguret via the steep little path, which leads to the village entrance. Join theGR®®4via the tarmac road leading out of the village towards the school, on the Route de Sablet.
(13) Before you reach the schools, when you arrive at the place known as Notre-Dame (chapel), take theGR®® to the right for a short climb, heading towards the chapel and Le Fournas via the Chemin de Sommier.
(14) Turn right into the woods to pass through Le Fournas. Follow theGR®® through the forest to reach the junction with theGRP®®, which leads to the Notre-Dame d’Aubusson chapel, about 1 km away.
At the junction, leave theGRP®® to your right and turn left to retrace your steps along the route you took on the way out, arriving back at the starting point (S/E).
