Start at Bois de la Gueule (Vita trail).
(S/E) Follow the tarmac road heading east-south-east, which starts opposite the start of the Vita course. When you reach a farm, take the road on the right. At the next crossroads, turn left onto the path running alongside the forest.
(1) After about 20 metres, follow a path on the right (south-southeast) which is not very visible at the start.
(2) At the junction with a wide tarmac road, turn left towards the motorway. Take the first street on the right. You will come to a path running alongside a small stream. Follow it to the left. At the end of the path (small bridge), cross the main road and continue on the pavement on the right.
(3) Go under the motorway bridge and take the path on the right that goes down to a crossroads. Then turn right to go back under the motorway. Next, take a path on the right that goes up the left bank of the Versoix (do not cross the bridge). This path leads to a tarmac road that takes you back to the main road.
(4) Cross the road, then follow it to the left and cross the Versoix.
(5) Take a look at the hydroelectric power station and follow the yellow markings on the right, which lead to the water supply canal to the power station. Cross the bridge and follow the canal upstream to its source. Cross to the other bank, either via a bridge in the middle of the canal (yellow markings) or by staying on the same bank and crossing the bridge at the water intake.
(6) Take the path on the right, which climbs steeply away from the river. At the junction with the tarmac road, cross over and take a wide path slightly lower down, which runs alongside large horse paddocks. When you reach the tarmac road, take it to the right, descending once again towards the river.
(7) To the right of the road is a large picnic area. Cross the Bossy bridge, then take the path on the left and stay on the path near the river. Continue to follow the river on its right bank for several kilometres until you reach the Sauverny bridge, which marks the French-Swiss border.
(8) Opposite the bridge, a path (marked in yellow) turns right and passes between a few houses before crossing fields: follow the yellow markings, turning left and then right.
(9) Pass in front of the Courtois Farm, then continue straight ahead and first turn left then right towards the Geneva Astronomical Observatory, which you will go around on the left.
(10) From the car park, take the access road (barrier). At the first crossroads, follow the wide dirt track straight ahead (south-east). Then take the first track on the right to join the main road.
(11) Continue straight ahead on the wide dirt track before taking the first path on the left. At the next junction, turn right. After crossing a stream, turn left and then immediately right. At the T-junction, turn right. Ignore the two paths coming from the right and continue to the woodcutter's hut.
(12) Turn left and you will immediately return to the car park where you started (S/E).
