The way, accomodation, resupply, daily stages, GPS track of the hike through Pyrenees from Carbonne (along Garonne river, south of Toulouse) to Pont de Suert in Spain through Ariege and Aigüestortes national park.
From Garonne through Ariege and Aigüestortes national park
Another beautiful hike north-south through the Pyrenees with superb landscapes in popular and lesser known areas and via several historic places.
Like many of my north-south hikes in the Pyrenees, I started from the foot of the mountains to approach them slowly and gradually. It is also possible to start from Toulouse by the Via Garona.
From Carbonne, the way goes through Volvestre, an area with amazing views of the Pyrenees and beautiful villages (Rieux-Volvestre, Montesquieu-Volvestre, Montbrun-Bocage).

After the spectacular passage through the prehistoric cave of Mas d’Azil, the relief becomes more mountainous. The high peaks are getting closer.

From Aulus, the way passes by the Ars waterfall then crosses the border via a little-used pass, the port of Sounou (or Guiló). On the Spanish side, to Guingueta d’Aneu, the path allows you to discover beautiful lake landscapes including those after Tavascan in a little-known valley.

The hike through Aigüestortes National Park is superb via the enchanting site of Maria Blanc, before leaving the high mountains through the very isolated Manyanet valley.

Useful information
Public transport :
It’s easy to go to Carbonne by train (Toulouse-Boussens-Tarbes line). To only hike the central part, take the bus from Boussens to Aulus-les-Bains via Saint-Girons.
During the summer period, buses from Pobla de Segur to Pont de Suert pass through Viu.
Barcelona-Vielha-Les buses pass via Pont de Suert with connection for bus line 395 from Les to Saint-Gaudens for return by train to the point of departure.
Difficulties :
It is a high mountain course with several passes above 2,500 meters in altitude, therefore with unstable weather and snowfields that can remain late in the season. The entire route is mostly on marked trails but in some parts the markings are light.
Trail marks :
Apart from some short parts, the whole route is on marked trails but sometimes these are only rare cairns. Being able to follow your GPS track will therefore be necessary.
Lexicon :
Bivouac: wild camping, usually according to French regulation, in a small tent (where you can’t standing) and pitched only for the night.
Abri: shelter. It’s unclosed (no door, some with just a roof) quite similar to those on the Appalachian Trail.
Cabane: small hut or shelter. It has a door. Some “cabanes” are occupied in summer by shepherds and open the rest of the year.
Refuge non gardé : unattended hut. Unlike a simple “cabane”, usually there are beds with mats.
Refuge: hut. You sleep in dorms, they can provide meals. Some of them even have showers.
Gîte d’étape: It’s like a refuge (or hostel) but accessible by road. You sleep in dorms (some have also bedrooms), they can provide meals. You will find “gîtes d’étape” on the main hiking trails.
Accomodation and resupply :
See the table below with my stages, shelters, refuges and shops.
Resupply : it is easy to resupply especially in the central part in Aulus-les-Bains and Espot.
Water : there is water frequently with fountains, springs and sometimes water from the river.
Accomodation : except after the Colomina refuge, it is possible to do the entire route without a tent by sleeping in hotels, hostels, refuges or cabins. From Colomina, possibility of continuing via the Boí valley with accommodation on the route. View page Cazères to Pont de Suert.
Bivouac : In the Aigüestortes y Estany de Sant Maurici National Park, bivouacs are prohibited, including next to shelters.
Internet websites :
For all France, the site gites-refuges.com is useful for information on huts and “gîtes d’étape” and that Refuges.info for huts and shelters.
Specifically for the Pyrenees, the site Pyrenees-refuges.com is very complete on this massif. It’s possible to download the gps position of all the “cabanes” and “refuges”.
In Spain, for information for huts see la central de refugis and the page for online reservations .

Maps :
For topographic maps of the French National Institute of Geography (IGN), see the website Geoportail.
With the website Brouter.de you can draw a GPS track following the existing ways and trails.
When I’m on my way, I’m using the Iphigénie application. With it, you can have offline IGN topographic maps (both for France and Spain). It’s also possible to send beacons of my position (if there is network); this can be reassuring on certain occasions.
GPS track :
For each stage, see important information below. Attention ! The trace below was redesigned when I get back. In all cases, the reality on the ground should be privileged. If passing through private land, ensure permission from the owner.
