From Briançon, take the N94 towards Montgenèvre.
Drive through the village, then at the obelisk roundabout, head towards the town centre and park in one of the car parks located past the town hall. Parking is usually free during the summer.
(S/E) From the car park, follow the boardwalk towards Italy for 300 metres alongside the car parks. Turn right (south-east) onto the small tarmac road leading to the golf course and Lac du Peychier.
(1) At the ‘Lac du Peychier’ sign, take the path on the right towards the Bois du Prarial and the small pass.
This path runs along a ledge above the golf course and crosses the Bois de Prarial.
(2) After passing the second sign for “Bois du Prarial” and at the Fork in the road, take the path on the left which descends towards the Doire torrent, a river which flows into the Adriatic Sea via the River Po.
(3) At the end of the path, take a small track on the left.
Cross the Doire then head south-east to join the Allée du Collet Vert.
(4) Follow the path uphill to the right.
The path climbs along the southern then south-eastern slope, following the course of the Doire.
(5) At the sign for “Sous la Plane”, turn left onto the path towards the Cime de la Plane and the small pass.
The path leaves the forest entirely, climbs through the mountain pastures and the summit comes into view on the left.
(6) At a cairn, leave the path leading to Collet Vert and take the track on the left.
This narrow mountain path climbs north-east then east before reaching, after a steep ascent, the Collet Guignard or Petit Collet.
(7) Head up the Crête de Petit Collet to the left for a distance of about 350 metres.
(8) At the cairn, leave the path and turn right towards the north onto the summit path of Mont de la Plane.
(9) After taking in the views, head back down the same route to the car park (S/E).
