Go to the Sommet Bucher car park, turn around, then take the road downhill and park just after thefirst bend below the road.
(S/E) Walk down the road for 100 metres, then turn left and walk uphill. The trail starts just past two blockhouse entrances on the left; continue straight ahead (south).
(1) Several paths lead to the Col des Près de Fromage: take the one heading due south, which is the most direct.
(2) Ignore a path on the left, continue south and you will soon reach the Col des Prés de Fromage.
(3) From the pass, continue south towards the Chapelle Saint-Simon.
(4) When you arrive in front of the chapel, above a fountain, take the path that climbs to the right at the edge of the forest. It sometimes disappears but reappears! Climb up to a clear plateau on the right. Continue until you find a well-marked path.
(5) Follow the regularly cairned path that crosses the Bois des Vallonnets and heads south towards the valley between the Pointe de la Selle and the Combe Arnaude ridge.
(6) At the foot of the valley, look for your next destination, the cairn at point 2745 between the Crête de la Rousse and Pointe de Rasis. Climb up the valley, heading south-south-east, and cross the stream several times (no particular difficulty).
(7) Follow the ridge to the right (south-west) and climb Pointe de Rasis.
(8) Continue south on the wide, grassy Crête de Rasis.
(9) At the end of the ridge, make a sharp turn to the right and descend towards the pylon (near the place called Le Passet on the map). Go around the pylon on the right to join a path further west.
(10) Follow the path to the right (north-west) and reach Col Fromage.
(11) Head north towards Fontaine Rouge.
(12) At the fork, keep right on theGR®®5(red and white markings), still heading towards Fontaine Rouge (north).
(13) At Fontaine Rouge, follow a forest track north and leave theGR®® which veers left.
(14) At the fork, take the path on the right that climbs to Col des Prés de Fromage.
(3) Follow the path north for about 100 metres.
(2) At the fork, take the path that branches off to the right. When you reach a small pass, be careful to turn right to reach the orientation table (no sign).
(15) Descend to the small pass, turn right then left to rejoin the clearly visible road (S/E).
