From Briançon, take the road to the Col d’Izoard, pass through Cervières and then Le Laus, and park in the car park at a left-hand bend at an altitude of 2,130 metres.
(S/E) Take the wide track leading to the Chalets d’Izoard (signposted ‘Fort de la Lausette’). Head towards them.
(1) Pass the ruined chalets and leave the fort trail on your right to take a path through the mountain pasture that follows the dry stream.
Cross the stream and reach a small lake.
(2) Leave the main path on the right, which leads to the Col des Peygus, and head up to the left (the path is intermittent). The route is clear, however, as you can see the Col de la Roya opposite.
Climb in a zigzag pattern up the slope, sometimes over rocks, sometimes through the grass.
Emerge at the Col de la Roya.
(3) Take the cairn-marked path on the right leading to a first summit, then continue left along a rough track to reach the highest point, which is about 100m further on.
(4) Descend via the same route to return to the car park (S/E)
