Description of the walk

⚠️ The Col du Portet is closed to cars from 8.30 am to 6 pm.

From Saint-Lary-Soulan, take the road leading up to the Pla d’Adet ski resort. At Espiaube, just after the Chalet de l’Ours, turn right onto the Col de Portet road. Park in the car park.

(S/E) From the Col du Portet, join theGR®®10(westbound).

(1) At the first ford, continue along theGR®®10towards the west. The path will then turn northwards and you will walk along the shores of Lac de l’Oule from the heights.

(2) When you reach this fork, turn right; the path on the left descends towards Lac d’Oule. Continue until you reach a junction where three paths meet.

(3) All three paths lead to the Bastan Mountain Hut. Take the one on the left, which will take you past the magnificent Lower Bastan Lake. Walk round the lake on the right, then head eastwards uphill (GR®10).

(4) Continue along the GR®10 (north) to go round two small lakes and then follow the largest of the middle lakes of Bastan. You’ll reach the Bastan Refuge.

(5) Continue climbing gently towards the Upper Lake of Bastan. Just before the lake, at a Fork in the road, leave the GR®10 and take the path branching off to the right (north-east), leaving the Upper Lake on your left. The path becomes increasingly steep as you approach the Col de Bastan.

(6) Turn right (south) onto the path running along the ridge leading to the Pic du Pichaley. The path becomes very steep.

(7) Once you reach the Pic du Pichaley, take in the 360° view of the Néouvielle Nature Reserve and its many lakes, as well as the Pic du Midi de Bigorre. Continue along the path to the south of the peak.

(8) Be sure to take the path on the left, heading east, which leads to the Col de Jétas, and not the path that continues straight on towards the south. Cross the Col de Jétas and continue south-east.

(9) At this point, you’ll have the choice of either taking the path that goes via the Pic de Mantarrouyes or a path that continues straight on, allowing you to avoid going via the peak (the one shown on the map). Watch your step – the scree can be slippery. Then continue along the path towards the south.

(10) Leave the path to join a ski run that takes you to the Col du Portet.

(11) At the Soumaye ridge, you can avoid taking the ski run all the way to the Col du Portet by taking a shortcut along a small path on your left (as shown on the GPS route), which will also take you there (S/E).

A truly beautiful hike – best started very early to enjoy the tranquillity of the lakes and the magnificent reflections of the peaks in them. An incredible view from the summit. And not a single other hiker to be seen from the Pic de Pichaley onwards. The climb up to the Col du Bastan is a bit tiring but not technically difficult. However, the path up to the Pic is hard to follow and very vertiginous for those who are prone to vertigo. At the top, the view is spectacular in good weather. Please note that the car park is limited to 50 spaces and the road is closed from 8.30 am to 6.30 pm in the uphill direction during the summer.

A superb hike with a gentle, busy start leading to some magnificent lakes, followed by a gruelling climb up to the Col de Bastan with a first panoramic view, then a second vertiginous climb along the ridge (the start is poorly signposted as the markers from the peak – a white square with a green flower – point in the opposite direction to the climb; rely on your GPS +++) but it’s well worth the detour as you’re rewarded with a breathtaking 360° view across the whole valley.
The descent into the plain is just as beautiful; we cut across the original path down from the peak to rejoin the GPS route. The end of the walk is very pleasant; we were on our own from the Col de Bastan for the rest of the walk.
A magnificent hike, but not suitable for everyone, as previous reviews have pointed out.

One of the most beautiful hikes I did this summer.
The lakes, the herds, the 360° view from the peak.
The "lakes" section is quite busy because it is really parish specific to Brittany, but the alternative route via the Pic du Pichaley is much less so because the ridge is not accessible to everyone.

The Pic de Pichaley is not marked, so you need to have a head for heights as the ridge is very impressive. Like many others, we turned back when we reached the Col de Bastan, which is already very impressive.
The end of the hike is not marked
Otherwise, the rest of the hike is really beautiful and accessible. There are numerous lakes where you can swim.
I will definitely return

Magnificent hike on 2 August
A minor setback despite the announcement that the pass was open, the pass was closed until 6.30pm, so we had to take the cable car to get to the start, adding 1km to the hike
The cable car closes at 5pm, so you need to plan to leave fairly early as we just managed to catch the last one
There were no difficulties until the last lake

However, the climb to the peak is quite tough, but our efforts are rewarded as the lake changes colour as we climb
You have to use your hands a little for the last part before the peak
The view from the top is magnificent, with a 360° panorama of all the lakes. It's spectacular
The return trip is sometimes a little difficult to follow, especially the last part where we couldn't find the path, but with the trail we were able to find our way
It's also worth noting that this hike is in full sun from start to finish, so avoid it in very hot weather

Hike completed in late June.
This hike is very beautiful, especially the view from the top of the peak with all the lakes.
The route and description are accurate.
As mentioned in previous comments, the climb up the peak after the upper lake is steep, so be careful on the last part (there is a risk of falling rocks and you may need to use your hands).
The descent on the south side is easier.

A lovely little November hike! Splendid views. As many people have pointed out, the section between the refuge and the summit is not for Sunday walkers... Take care in wet weather.

Please note that the Portet Pass road is currently (until September) open for ascents only before 8:30 a.m. or after 6 p.m. Otherwise, take the cable car (which is not cheap...). In addition, the number of spaces in the current car park is very limited, so access may be blocked from 7 or 7.30 a.m. if several motorhomes have spent the night there and holidaymakers arrive very early (in the event of daytime storms forecast by Météo France).
Yesterday, Sunday 11 August, there were relatively few summer visitors early on, compared to my previous memories, in the first part up to the refuge, but quite a large number of hikers doing the GR 10. For the second part, which is more mountainous, there were few visitors, as usual.
A magnificent circuit, as always when the weather is fine...
As we were with two young teenagers who arrived at the summit of Pichaley a little exhausted, we descended directly from the pass through the meadows to the pastoral track, without taking the ridge path...

A challenging hike. The starting point is inaccessible by car, as the Portet Pass road is closed for most of the day in summer, but you can reach the start of the hike via the Espiaube cable car for €11 return, which takes you to a peak 10 minutes' descent from the start and 15-20 minutes' climb on the way back.
The path becomes less easy to follow on the descent from the Pichaley peak, so it is best to have a GPS with you

A magnificent hike, the various lakes of Bastan are stunning and perfect for camping. Be careful, though, as the climb up to Pic de Pichaley from the Col de Bastan is quite impressive and a little tricky for those who suffer from vertigo. The descent down the Col de Jetas, on the other hand, is very easy.
The return to the car park as mentioned on the information sheet is not necessarily easy to find in the middle of the mountain pastures/ski slopes, but it doesn't matter, as the return journey is not a problem in any case.

A superb hike for two with a dog on a leash (please respect the park and its livestock at this time of year). Start at the top of the ski resort and follow a loop starting with the lakes. These magnificent lakes are perfect for a break at any point along the way. The most challenging parts of the hike are the small pass after the last Bastan lakes (a steep but short zigzag climb, barely 10 minutes) and the Pichaley peak, where you may need to use your hands for support. Be careful of the first snowfalls, which create slush on the trail, making it difficult to see on this peak.
If you have a dog, it must be comfortable with these two climbs.
In any case, it's a magnificent route offering stunning views, especially after the two climbs (incredible 360-degree views).

We wanted to drive up to Lake Bastian from the Portet Pass, but the road is closed between 8 a.m. and 3 p.m. in July and August, apparently due to roadworks. We decided not to go, even though we saw a few cars driving along the road.

The terrain is a bit unstable from the pass onwards, but with caution, there's no problem. I enjoyed this loop, which I found fun and breathtakingly beautiful. Thank you for sharing

Having climbed Pic de Madamète the day before and not wanting to overdo it, we only did the lake route, which is already beautiful in itself.
I made a video, which you can find here, showing the route and giving a good impression of the atmosphere on this magnificent trail.
