Access: Park in the "Parc de Libertés" car park on the Ile de la Barthelasse. Leaving from Avignon, turn right after the Daladier bridge, you are now on the D228 (Route de l'Ison). After the Avignon lock located to your left, take the first road to the right to find the car park.
(S/E) Leave on the small trail the closest to the water (going directly east). Without making too much noise, you can see the various birds that inhabit these banks. The small path will join a large track. Stay on this track until the crossroads before the eastern arm of the Rhone.
(1) Opposite the eastern arm of the Rhone, take the path to your left along the fence, and go between the two stretches of water.
(2)When you get to a gate, turn right. Continue on this path until a metal gate signposted "Rhône/Ventoux". Turn right, a blue concrete post means you're on the right track. After the second blue post, turn right and then immediately left.
Stay on the largest path and you'll see where the Rhone splits. Go around to the left on the large path (west) and you'll come to the dam. Ignore the track that goes off to the left and join the access road to the Sauveterre dam.
(The site is currently undergoing work, so be very careful)
(3) Take the asphalt road to the left for a few meters and then turn right to go around the "Unnamed" power station. Pass the small canal, join the highest path that runs along the second arm of the Rhone.
(4) This is the northern tip of the Ile de la Barthelasse There's a viewing point over Mont Ventoux, Châteauneuf-du-Pape etc.
Turn left while remaining on this path, and go as far as the Villeneuve bridge.
(5) Go under the bridge, take an immediate left and join the track after having crossed a small canal. Stay on this track, with the road to your left and the small canal to your right.
Continue straight at the barrier.
(6) This path takes you back to the road that you cross to reach the car park(S/E).
