Park in the Mistral car park in Guilherand-Granges (opposite the stadium).
(S/E) Go to the northern end of the car park, close to the children's playgrounds. Turn right and join the cycle path (Voie Bleue). Follow it to the left for a few metres and continue to the right on a path closer to the Rhône. After an observation platform, the path rejoins the cycle path. Continue to the right on the cycle path until the next junction about 50 metres further on (fixed bars of the fitness trail on the left).
(1) Turn right and continue along the banks of the Rhône to return to the Voie Bleue. As before, follow it to the right to cross a footbridge reserved for pedestrians and two-wheeled vehicles (at the end of the bridge there is a fountain on the left). Take the path furthest to the right, which turns left and continues along the riverbank. Stay on the right-hand path closest to the Rhône, ignoring the paths on the left. When the space opens up, the path soon reaches a junction with the Voie Bleue.
(2) Turn right and continue along the Rhône. Cross a ford (water intake on the left) and continue straight ahead on the cycle path (ignore a path on the right that is not shown on the map). After about one kilometre, at a place called Le Moulin, cross another ford and a barrier (snack bar on the left in season).
(3) Continue straight ahead on the tarmac road for about 500 metres, then turn off for a moment to cross a picnic area with a car park. At the far end, you will find a signpost. Turn right towards Châteaubourg, pass a barrier and immediately turn left to rejoin the cycle path. Follow the railway line for almost a kilometre on the tarmac road until you reach a crossroads.
(4) Turn right onto the road, which quickly curves to the left and crosses an area of orchards. When the road makes a sharp left turn (with Châteaubourg in sight), leave it and follow the path on the right that enters Île de la Traverse and leads to the foot of the castle.
(5) Turn right onto Rue du Quai Saint-Louis, then left to go up Rue de l'Apuya. Leave the street on your right and you will arrive at Rue du Château. Continue left at the corner of a beautiful building, then the street quickly turns right and becomes Rue du Petit Puits. Start the descent, leave the street on your right and arrive at the bottom of Rue du Rhône. Follow this street to the right until the next intersection.
(6) Turn left at the corner of the cemetery and continue along the tarmac road. Continue through the orchards, pass another cemetery (on your right) and you will reach a crossroads. Continue straight ahead (ignore the road on your left) and you will reach the crossroads you took on the way there.
(4) Follow the same route as on the way there.
(3) Pass the ford (snack bar on your right), the car park and the picnic area, and continue along the same path to Île de la Grande Traverse and the cycle path junction after the bend.
(2) Continue on the cycle path on the right, pass a water intake and follow the path that turns left into a bamboo grove. Follow the Voie Bleue straight ahead, ignoring the paths on either side. Cross the footbridge, the cycle path slopes to the left and, just after that, leave the path on the left taken on the way there and continue straight ahead on the Voie Bleue. Cross the fitness trail (fountain at the end of the BMX track) and return to the crossroads you passed on the way there (horizontal bars on the right).
(1) Continue straight ahead on the cycle path until you reach the children's playground and car park (S/E).
