When you reach the Chapel of Houndas, take the road on the left and continue for about 600 metres until you reach a small car park on the right.
(S/E) Take the tarmac road and continue straight ahead. Near a fountain, you will reach the crossroads of the path in a hairpin bend.
(1) Take the dirt and stone path opposite, leaving the road on your right. Join it again further up.
(2) Follow the stony road and reach the junction with the path that cuts across the bends in the road.
(3) Continue along the road, note the signpost for Cabane Lasbordes, then come out onto the small plateau (altitude 1,329 m). Continue for another hundred metres or so along the stony path and then take the trail that leads to the Col d'Aran. A few cairns help you to follow this fairly well-marked trail. You will reach the foot of the pass.
(4) Note: Col d'Aran is only 200 metres away, but there is still snow on the ground on 10 May 2018. Change the route around the pass by going around the hill on the right to reach Crête de Saubajot via an easy route.
(5) Return via the same route to the trail junction.
(3) Keep right, taking the yellow-marked trail that rejoins the road further down.
(2) Then follow the same route as on the way out to return to the car park (S/E).
