(S) Set off from the swimming pool car park, taking the small road leading to Smarves. At the next Fork in the road, turn right until you reach the junction with the cycle path along the Route de Gençay.
(1) Turn left onto the cycle path, go past the roundabout and continue along it until you reach the junction at the Ferme des Eulées.
(2) Take the dirt track on the left. Keep heading south-east and ignore the paths on the left. At a junction (elevation 137), continue straight ahead. Then ignore a path on the right and start a left-hand bend along a field.
(3) Follow the path at the edge of the woods that runs alongside the field and enter the forest, staying on this path. You will come to a multi-way junction; ignore the first two paths branching off to the right and left and continue straight ahead. A few metres further on, you’ll come to a second three-way junction along a plot of land with a hut on the right; take the small path on the right running alongside this plot. Continue along this path until you reach a small hut at a junction.
(4) Then take the path on the left. Continue along this path, ignoring a turn-off on the left, until you reach a junction.
(5) Turn right and walk for a few hundred metres until you reach the next junction with theGRP® des Trois Batailles de Poitiers.
(6) Continue straight ahead towards Château Saint-Pierre.
(7) At the junction, after the descent and before heading back up towards the castle, turn right onto the path called Vallée de Montfrère. At the next Fork in the road, turn left and follow the path for about 1.8 km, ignoring the side paths and taking a wide bend to the left. You will reach the Étang du Bois de Saint-Pierre.
(8) Turn left onto a path that climbs towards Château Saint-Pierre, mostly via steps. At the entrance to the château, cross the grounds and exit through the gate opposite. Continue along the path to the playground.
(9) At the junction by the playground, take the path on the right to the swimming pool car park (S/E).
