Public transport does not go this far. You will need to take your own vehicle and park in the car park on the left after the hamlet of Les Serrigues, coming from Gap, on the site of a former quarry.
(S/E) Walk to the back of the car park and take the path leading up into the forest directly in front of you.
(1) At the Serrigues Hautes signpost, turn right towards Col de Gleize. The path climbs gradually, alternating between forest and scree.
(2) At the Col de Gleize signpost, near the gate, head towards Pic de la Greysinière. The path climbs through the forest via numerous hairpin bends up to Pic de la Greysinière.
(3) Caution: Continue due south along the path along the ridge. The climb may be difficult for those prone to vertigo. Fortunately, the markings (yellow lines and arrows) help you find the best routes. Take care not to stray from the path.
(4) After this somewhat challenging section, the path continues across open mountain pasture! But be warned, this is where the rollercoaster ride begins!
(5) At the Col de Côte Gelée:
- you can take a shortcut by following the path that descends the eastern slope and joins the route taken on the ascent.
- Otherwise, continue along the ridge. There are two more hills to climb before reaching the Col de Guizière.
(6) Turn left towards Les Serrigues, route no. 3. Begin a somewhat steep, rocky descent lasting about ten minutes.
(7) At the Gap signpost – Alt 1540 m, keep straight ahead towards Les Serrigues. Descend through the forest until you reach the Les Serrigues Hautes signpost.
(1) Head straight on along the short section of path taken on the way out to return to the car park (S/E).
