From Embrun, head to Caléyère via the D465, then to the Château de Caléyère. On leaving this hamlet, park on the right just before a building with several doors facing you, on which there is a sign reading “No parking – Turning area”.
(S/E) To the left of this building, take theGR®50long-distance footpath which leads you to the Sainte-Marthe stream.
(1) Cross the stream (fording point and a makeshift footbridge if necessary). Look up to spot two crosses on a tree above the signpost: one red and white, the other yellow and white. Head towards this tree, leaving theGR® to begin the climb to the right along the stream, on the upper bank.
There is a climb of nearly 400m on a zigzagging path, somewhat disrupted by forestry work in one section, but pink paint markings will guide you through this area. Along the way, you will find a stone on the ground bearing the number 82 with a double arrow. 10m after this, turn right to rejoin the old path.
(2) At the junction with the forest road, you will see a barrier blocking the road ahead. Head right towards it, then proceed to a cistern (a water reserve for firefighting).
(3) Take the path that climbs to the left of the cistern, then cross the stream (via a designated crossing) and continue until you reach a forest road.
(4) Cross the road and turn right onto a path towards the Chapelle des Séyères – 1.5 km (signpost).
(5) At the signpost, turn left, still heading towards the Chapelle des Séyères – 0.2 km.
(6) The chapel, the spring and a few picnic tables await you. To return, follow the route you took on the way up, heading back to the junction on the forest road.
(4). At this point, turn right onto the forest road, heading towards the “Circular VTT des Fontainiers”. Don’t panic, you are indeed on mountain bike route no. 4, but mountain bikers are few and far between at this altitude.
The forest road turns into a pleasant downhill path leading to the Selle de la Pelle viewpoint, also known as the Para viewpoint, where you’ll find an orientation table offering a 180° view. The MTB4 markings will guide you to the viewpoint.
(7) Turn left onto the forest road, heading towards “Porte de la forêt”.
(8) Leave the forest road before reaching the car park by taking a path on the right, which is rarely, if ever, used and not very visible, allowing you to cut across a bend in the forest road.
(9) Back on the forest road, 5m to your right, the path continues, cutting across another bend.
(10) Back on the forest road, follow it past an immediate first hairpin bend, then a second, followed by a wide bend to the right.
(11) As you come out of this bend, on your left, look for a clearing where a path runs; it is barely marked at first on the forest road but becomes clearly visible enough to allow you to join theGR®50, which is also the route of mountain bike route no. 4.
(12) Once you are back on the forest road (GR®50), head down to the left towards the Sainte-Marthe stream.
(1) Continue along theGR® you used at the start of the hike to reach the car park (S/E).
