The starting point is at the Rocher de la Dube climbing site, between Mérigny and Rives, on the edge of the D50.
Follow the yellow markings of the route proposed by the Brenne Regional Nature Park, entitled: Between the cliffs and hillsides of the Anglin.
(S/E) Join the D50, which passes at the foot of Rocher de la Dube, and follow it carefully north-west for 400 metres. Go up a path on the right, then turn left twice. Further on, leave a path descending to the left and join a small road.
(1) Follow it to the right for 50 metres, then take a farm track on the left. Turn right to climb up to Beauchapeau.
(2) Turn right and immediately follow the road on the left. Continue straight ahead at the next intersection towards La Vieille Grange. Pass a track on the right and cross the hamlet. Continue along this small road to Rives.
(3) Carefully follow the D50 to the right and, just after a bridge, take a carriage road on the left. Pass Rocher St-Berthomé and its cave and go to the end of the road to reach the site of the old Moulin de Braud.
(4) Go up the grassy path on the right that passes in front of a house. It becomes a gravel path in the undergrowth and a carriage road at the edge of the woods as you approach Fournioux.
(5) Carefully follow the D3 to the right, cross the hamlet and continue on the D3 towards Fontgombault for 300 metres.
(6) Take a farm track on the left, then turn right. Carefully cross the D3 to take the small road opposite, towards Coreil.
(7) Follow the track to the right, which turns left further on. Then continue straight ahead on a forest track, leaving the track that veers off to the right.
(8) Be careful because 100 m further on, continue straight ahead south-east along a path not marked on the IGN map (but present on OSM), leaving the previous path turning right. Follow the yellow markings, ignoring the various forest tracks.
(9) Follow the track to the left for 25 metres, then turn right onto a forest track (signposted yellow and blue routes). Continue straight ahead to leave the woods and cross a field. Leave a path on your left and pass under high-voltage power lines, then join the small D95 road at Pertuis au Loup.
(10) Turn right and follow the road carefully for 400 metres. Take a path on the right in line with the high-voltage power line, then, 30 m further on, turn left onto a stony path in the undergrowth which will take you back to the starting point (S/E). You can then climb up to the right for a 300 m round trip to the Rocher de la Dube (caution: steep ascent and descent!).
A hike that we were unable to complete.
