Parking is available in Nans-sous-Saint-Anne, opposite or to the left of the town hall. Yellow and blue signposts.
(S/E) Head towards the church, which is worth a visit for its beautiful statues. Turn right up Rue du Château. At the foot of the beautiful turreted house, turn left up Rue Cretin (signposted Le Vernau). At the fountain, turn left towards Source du Verneau (green sign), passing beautiful old houses. After a small bridge, climb up to the waterfall on the right via a small stony path and a few steps. At the metal footbridge, despite the yellow and blue cross, continue with caution along the steep and slippery path on the left.
(1) Then return to the centre of the village, pass the church and the town hall/school and head towards the Sainte-Anne — Crouzet Migette hike. After the bridge over the Lison, follow the signs to the taillanderie.
(2) At the fountain, turn left. After a small stone bridge, follow the signs for Source du Lison — Creux Billard — Grotte Sarrazine on the left.
(3) At the lodge, the path forks; follow the left fork that runs alongside the Lison. If you wish to visit the Taillanderie, take the right fork.
(4) Go past a wooden footbridge and head towards the Grotte Sarrazine, a "wild cathedral" with a large archway 100 metres high and 30 metres wide carved into the limestone rock. Return and cross a footbridge, then a second one, and turn right at the Lison spring. Take the small footbridge opposite the spring and head right. Follow the signs to Creux Billard, then turn back.
(5) At the signpost, head towards Chêne remarquable — Nans-sous-Sainte-Anne along the path that climbs the hillside, following the yellow and blue markings. At the foot of a huge oak tree, turn right towards Crouzet-Migette.
(6) You will reach the D103, which you follow to the right until the first hairpin bend. Along the way, there is a viewpoint over the valley and the village of Nans.
(7) At the wooden cross, turn left onto the road in the bend and follow the GRP®. After 200 metres, the trail turns left onto a path that climbs through the forest.
(8) Join a carriage road that continues along Rue du Derouchou and pass in front of the Chevrie buildings. You will arrive at the D103.
(9) Cross it and catch up with the GRP® trail opposite, which descends to the right and reaches a road.
(10) Take the left-hand track. Be careful! Immediately after crossing the Château Renaud stream, leave the stony road and take a small stony path that climbs up to the right. It quickly becomes a more or less well-maintained and slippery track.
(11) You will reach a gravel path which you follow downhill to the right. Follow the GR® which runs along the edge of the pasture.
(12) The path seems to end in a cul-de-sac. Look for a small trail on the right that winds through the tall grass. You will enter the woods. Look for a sign for Nans-sous-Sainte-Anne on one of the first trees. The path then forks. Take the path uphill towards the viewpoint (sign) and follow the markings and crosses indicating which paths are closed.
(13) You will come to a crossroads marked by three signs. Take the left-hand path towards Vestige du Vieux Château — Belvédère.
(14) Turn back. About 700 m after the viewpoint, after a slight climb and about 20 steps after a sign for Vestige du Vieux Château, look for a small path on the right (a little further on, you will see the sign for Nans-sous-Sainte-Anne, which is not very visible from the path). If you miss it, don't panic, continue to the previous crossroads and go down to the right; the two paths rejoin. Go down to the point where you see the sign for 'Nans-sous-Sainte-Anne' and continue downhill to the left towards Nans.
(15) As you leave the woods, follow the sound of water and you will see the old axe factory and its water wheel through the branches. You will soon reach the lodge and return to the centre of the village and the car park (S/E).
