Start from Allinges Church. Car park located between the D233 road and one side of the church (if there is no space, park in the car park opposite the church).
Signposts are located at all major intersections. Yellow signposts with arrows are found at various points, indicated in the description only where necessary. This system is supplemented by signposts along most of the route.
Round blue markings (usually on the ground)
(S/E) From the car park next to the church, with your back to the church, take the small street opposite which climbs towards the castles. At the end of the tarmac road, after about 100 metres, turn right onto a shaded path towards the castle car park. At a fork (signpost), take the right-hand path and continue on fairly level ground through the woods.
At a T-junction, cross a stream and follow a wider path on the left. Continue steadily uphill on this stony path through the woods. Ignore a path leading down to the right (this is theGRP® Littoral du Léman) and continue uphill, following the occasional red and yellow markers. At the top of the hill, you will find the castle car park on your left.
(1) Follow a small road on the left towards Château Neuf and Château Vieux. Climb uphill, pass under two successive stone arches and enter the Château Neuf estate. At the top of the hill, you will come to a junction with signposts.
No signposts
(2) Turn right towards the chapel, pass at the foot of a statue of Saint-François de Salles and turn left onto the castle terrace to visit the chapel. Retrace your steps.
Round blue signposts (usually on the ground)
(2) Head towards the viewpoint opposite (panoramic view of Lake Geneva). Continue to the right (north-east) towards Château Vieux. Walk down along the railings, pass an information sign on the right-hand side of the path and continue towards the ruins of Château Vieux. Climb up to the ruins via a path and steps on the left-hand side (north). Go through a gap in the wall and under a narrow porch. Turn right and climb up to the foot of the keep (small terrace with a flagpole flying the Savoy flag).
(3) Go back down and continue to the right (east-northeast) and stay on the north side of the ruins. Go down along the railings and, at a signpost, turn left. You will reach an information board. Leave Château Vieux through a gate in the surrounding wall.
No signposts
(4) At the crossroads immediately after leaving the enclosure, take the left-hand path towards Allinges (main town). Descend, following several hairpin bends. At a hairpin bend to the right (signpost), leave the path and take a narrower path on the left (be careful not to miss this discreet start).
Red and yellow markings
After a few dozen metres, at a crossroads, turn left (marker; look for a signpost further on). Descend on a wide path and ignore vague paths on either side. At the crossroads at La Rottaz (signposted "Altitude 585"), turn left towards Allainges (main town).
No markings
After a few metres, at another crossroads, turn left (west) and continue downhill. At the houses and as you approach the D233 road, turn left and climb briefly up a stony path. After a few metres (signpost), leave this path, take a grassy path on the right and pass at the foot of a rock block on the right-hand side.
Climb a path interspersed with wooden steps. At the top, follow a discreet path that veers to the right (do not take the wide path further to the left). Opposite a house, turn right and descend. Return to the first crossroads you came to on the way out and continue straight ahead to the church (S/E).
