Description of the walk

Departure from the car park at Sentein Place de la Mairie.

(S/E) Turn left, pass the post office and continue along Rue d'Antras (D704c).

(1) Leave the road and take the path on the left, which crosses it twice before rejoining it at the entrance to the village of Antras.

(2) Continue left on the road to enter the village. At the crossroads, turn right and continue straight on the road, which then gives way to a path. Ignore the paths on either side and continue to a three-way junction.

(3) Turn left and continue westwards. Pass several pretty cabins cut off from the world, most of which are still inhabited.

(4) Pass close to the Cazaux fountain. Further on, leave the path on the left that leads to Col Méda and reach Col de la Croix.

(5) This is the ideal spot for your first break after about an hour's walk. Take the first path on the right, which curves sharply to the right and heads west. Pass several paths on the left and reach a fork after crossing the Ruisseau de Couledoux stream.

(6) Turn right and follow a few hairpin bends before quickly reaching the pretty pastoral hut perched on the mountainside. Continue to Col des Morères.

(7) Once again, this is a pleasant spot to take a break before climbing Pic de Sérau. Turn left at a 90° angle and head north, straight up the slope, to reach the peak.

(8) Turn right to follow the pretty ridge. Pass successively by Pic de Mardans, Col de Portet (9) and Pic de Moussau (10) before reaching Pic de l'Arraing, the destination of this hike (very beautiful landscape, soothing calm).

(11) Leave the ridge and begin the descent on the right to the small hut at Col de l'Arraing.

(12) At the crossroads just after, ignore the path on the right and continue straight ahead on the south-west facing path.

(13) At the edge of the forest (elevation 1181), turn left. At the T-junction, turn right and descend to the access road to the hamlet of Balacet (D704).

(14) Turn right and cross the hamlet, following the road straight ahead. Leave the road at the left-hand bend and continue straight ahead on the path, which remains almost level, to reach Irazein.

(15) Cross the village, turning left between the houses. Come out onto a small road opposite the cemetery and follow it to the right. At the hairpin bend, leave the road and take the path on the left which leads down to the D4.

(16) Turn right towards Sentein. After passing the school (on your left), turn right into Rue du Commerce to return to the car park where you started (S/E).

Notes

You will need day-trip equipment, a picnic, a first aid kit, a beacon, a GPS, an altimeter, a map and a compass. Warm clothing and gaiters may be necessary at the summit.

Cabane du Col de l'Arraing: ideal for a well-deserved break or even to spend the night. Nearby is a drinking water fountain (may be frozen in winter) as well as a fireplace and a dormitory area upstairs. For those wishing to spend the night, bring a sleeping bag and extra food.

(15) For your information: in Irazein there is a baker with a traditional, authentic wood-fired oven who makes very good bread. "Please note that he does not serve on Sundays and you need to book in advance to be sure of getting your bread".

Almost exclusively uphill through the forest. Beautiful view at the top. Pleasant descent. Lots of mud on the way up

A magnificent, fairly accessible route, but beware of the lack of water on the way (many passages on the ridges, so no water). The path is rather poorly marked on the final climb to the Pic de Serau and there can be some confusion on the path linking the Pic de Serau to the Pic d'Arraing (follow the ridge and don't go below it, there are a lot of nettles which can spoil your hike!) Otherwise I recommend this hike, and the paths should be better marked in summer.

A very beautiful hike, it is a good 16 km (be careful to take the correct turn at point 9!).
We completed the hike in slightly less time than advertised, and the section along the ridges is very enjoyable. Be patient when you reach the top, as there are sometimes clouds and fog, but the view always clears up in the end!
Thank you for the route 🥾

Very beautiful route, but it is 19 km (not 16) and you should wear long trousers, as the ridge is covered in nettles 😬 With herds of cattle and sheep passing through, the actual path is sometimes difficult to find....

A varied hike offering magnificent panoramic views. No particular difficulty (hike done in dry, sunny weather), but requires good physical condition.

Only attempted in good weather conditions, using the highly reliable GPS track.
The climb to Pic de Sérau is quite steep and requires a bit of judgement (as there are many sheep tracks).
The same applies to the ridge crossing, which is easier but a little rough (not smooth). But what beautiful views over the two valleys; a real treat!
This hike should be done in good weather and is only suitable for people in good physical condition.
Thank you for this hike.

A beautiful route that is better than the Birros tour suggested on the IGN map.
The ridge line is very good.
The "Pleine Pente" section between points 6 and 7 requires a bit of judgement.
A beautiful hike, albeit a little challenging.
