Continue straight ahead and, at the foot of a second staircase, turn right and leave a large kiosk and then some ponds on your right. At the bridge on the right, climb the stairs on the left.
(5) Wander around the upper part of the park as you please (suggested route): artificial stream, ponds, modern sculptures, beautiful trees, etc.
(5) Climb the paved path that goes around the large pond on the right (it is the first path on the right when you reach the top of the stairs coming from the lower area). Ignore a path on the right and go around the top of the artificial waterfall on the left. Continue, passing a dovecote on your left. At the crossroads immediately ahead, continue straight ahead and pass a ping-pong table. At the end of the path (not shown on the map), take the Allée de l'Hôtel de Ville on the right for a few metres, then turn left onto Rue Jean Douat.
