Park in the car park at the entrance to the village of Sem.
(S/E) Follow the D208A road up to the junction with the Village path, which starts on the right.
(1) Continue along the road to reach the Col de Sem and its cross.
(2) Turn right and continue for a few dozen metres to reach the glacial dolmen at Palet de Sanson.
(3) Return to the pass via the same route.
(2) Head back down the road towards Sem and return to the junction with the Village path.
(1) Turn left onto it, follow the path down for 250 m and, after the first houses, turn right up the steps to return to the car park where you started.
(S/E) The circular route begins now. From the car park, which is on the right-hand side of the road as you come down from the pass, look for the stone shelter and take thePR®® short-distance hiking path, marked in yellow, which climbs to the left heading due south (accessible to small 4x4s). The path is wide and stony and climbs quite steeply through the woodland: the stream is on your left. Ignore the first path coming from the right and continue to a second junction.
(4) Take the path climbing to the right; this path, still the yellow-markedPR®®, is wide and well-marked. Follow it to reach a crossroads with several directions.
(5) Keep straight on thePR®® to reach the paragliding launch site at Col de Risoul.
(6) Go back a short way and turn right down the forest track. You will soon reach the Nagot Forest Shelter.
(7) Leave the forest road here and turn left onto a narrow path that is not always clearly marked and is sometimes overgrown with broom. Shortly after a small, fairly well-defined valley (thalweg), with a spring below, the path takes a sharp left-hand bend to reach the spring. Leave it on your left. Continue along the path, which is still rarely used and overgrown with broom. You will then reach thePR®® junction you passed on the way out.
(5) Turn right onto thePR®® again and follow it to the junction you also passed on the way out.
(4) Turn right towards the Ruisseau de Sem and cross it. Continue along the well-marked path, which then climbs slightly. Cross another stream, then pass a cross overhanging the path on the right before reaching the fenced-off Galerie de l’Auriette and the Anciennes Mines de Rancié, whose large cave-like entrance is on the right.
(8) Start a new descent on the left via a series of hairpin bends, passing in front of the Font du Minier. Return to the village of Sem. Cross the Ruisseau de Sem once more before returning to the village car park (S/E).
