Towards the Blue Lake
The Blue Lake
ascent to Lac Bleu
Stone path to access Lac Bleu

Description of the walk

The walk starts from the Chiroulet car park in the Lesponne Valley, which can be reached by turning onto the D29 after Baudéan.

(S/E) Pass the inn and head towards the Adour, which you cross via a large bridge.

(1) At the power station, take the path on the right that winds its way up through the woods to a circular basin at the edge of the forest.

(2) Continue along the path, which becomes steeper and winds its way up to the Lac Bleu.

(3) Enjoy the deep blue lake, which is simply sublime in good weather.
Return by the same route (S/E).

Hike completed at the end of 2025

A very beautiful hike with no major difficulties
At this time of year, the ascent and descent are in the shade. You'll find the sun again at the lake.

Easy access to the car park. The first snow is higher up from the water reservoir.

Remember to bring appropriate equipment for the conditions, such as hiking boots and walking sticks.
Consider crampons as the path along the slope is a little slippery with snow.

The second bridge has been dismantled, but it is possible to cross the river above it.

The view at the top is magnificent.

Not many people at this time of year, which suits me fine. Probably too busy in summer. Good facilities at the start, car park, very clean toilets, bins, a great restaurant to try, opens in April. Easy climb, wide path, shaded at this time of year. You discover the lake and the sun at the same time. The sun hides behind the peaks around 2.30/3pm. A family walk.

The walk through the forest and then across the meadows is fairly easy, then it starts to climb and the final view is impressive. What's more, it had snowed during the night, making for a very pleasant panorama

A very beautiful hike, it's a bit of a climb but well worth the effort... The green lake isn't very far away

I advise hikers to take their time going up and down, provided the weather is good, of course. The key is not to overestimate your abilities. We pushed on to the green lake. Be careful, as the path to the green lake is quite technical, but not for long. Be careful in the mountains, because I think we've broken the accident record this year, haven't we?

It was my first hike, it took me 3 hours to climb up and 2.5 hours to climb down. It was quite hard but doable, the view is magnificent and so is the lake

The route is relatively easy, which explains why it is so popular. If you want to make it more challenging, you can take the shortcuts. The setting is beautiful and the view at the end is superb.

Everything was as described, a very pleasant hike and a beautiful lake. The estimated time of 5 hours and 55 minutes is very generous. It took us 4 hours and 20 minutes, and we're not exactly sprinters.

A beautiful hike, just as described. Two hours of relatively challenging climbing rewarded by the view of the magnificent Blue Lake.
As I still had some time, I went on to the small Green Lake. The climb was short but with some fairly steep sections, but here too the views of the two lakes are magnificent.
NB: beautiful sunshine that day!

From the blue lake, it is easy to climb up to the green lake, requiring a bit of climbing with ropes, but without any major difficulties, and offering a beautiful view of the blue lake from above.

In the footsteps of Georges Buisan, born in 1924 in Montréjeau (Haute-Garonne) and resident in Tarbes, he spent his childhood in Bigorre. His interest in the mountains led him to spend several years researching shepherds' huts. Georges Buisan has since passed away, but he leaves behind him, with this Courtaou de la Lit, which he restored over a period of thirty years, an original legacy and a powerful message.
