The Sant-Guillem Refuge via Coll de Rua - Cortal d'Allosat from La Llau

A hike in the Haut Vallespir along a small road, forest tracks and a PR® trail.
The route takes in beautiful pastures, a sheepfold, the Sant Guillem mountain hut and chapel, and an arboretum.
See the section ‘During the hike or nearby’.
This hike is the shorter version of my hike ‘The St-Guillem refuge via the Coll de Rua and the Estanyol from La Llau’

Description of the walk

From Perpignan, head towards Le Boulou (D900) then Céret, Amélie-les-Bains and Arles-sur-Tech (D115). Continue on the D115. On leaving Le Tech, turn sharp right and head uphill along the D74a towards the hamlet of La Llau (L’Allau on IGN maps). Caution: the 7 km road, which is in good condition, is narrow in places. Drive past the hamlet and continue for 500 m; after the road bridge, you’ll find a car park on the right-hand side.

Unmarked route

(S/E) From the car park, retrace your steps along the D74 back to the hamlet of La Llau.

(1) On leaving the hamlet, at the water source, turn left and head uphill along the small, potholed road towards the Coll de La Roua (elevation 1,013). The potholed tarmac road ends at the pass.

(2) Continue along the track towards the Sant-Guillem refuge. There is a large steel gate with “Sant-Guillem” engraved on it. After a sharp bend, the track becomes concrete and climbs due north.
At an altitude of 1,134 metres, where the concrete ends, at Mas Ventós, look for a grassy track on the right that leads uphill.

(3) In case of any unforeseen circumstances, you can go directly to the refuge by continuing straight on along the track.
Otherwise, at the end of the tarmac section, turn right onto the grassy track, go through the gate, and continue climbing towards the antennas (at around 1,135 m), where you’ll also find the EDF facilities for the penstock – which you’ve crossed several times since setting off.

(4) This is a hunting area; a high-visibility vest or a brightly coloured outer layer may be useful in the presence of 4x4s and hunters to ensure you are clearly visible. Signs reading ‘Hunting in progress’ are usually displayed. Make yourself noticeable and ask for permission to continue.
- This track, which stays on the grassy ridge facing due north, offers magnificent scenery throughout the steady climb. Keep heading north. Pass an electrified fence and arrive at Pla de la Faja, where the track then turns north-west. On the right-hand side, a sign is affixed to a very large boulder.

(5) Note the semi-buried sheepfold (Cortal Allosat) on the left, nearly fifty metres long. The slate roof is magnificent. The entrance has been beautifully rebuilt using dry stone and is closed by a padlocked gate (observed on 15 December 2024). Please do not climb onto the roof. Thank you.
150 m further on, continue to the right and you will come out onto a wide track suitable for vehicles.

(6) At this crossroads, at an altitude of around 1,360 m, cross the electric fencemaking sure to close it behind you – and head left, due west, along the track. There are beautiful views here too. After 2 km, you’ll reach another track at a broken wooden gate.

Yellow markings

(7) Turn left onto this track towards the Refuge de Saint-Guillem. Higher up on the right are the chapel and a house, both private, and at the side of the track is a large abandoned building.

(8) In season, the Refuge de Sant-Guillem offers accommodation, food and drinks. Very warm welcome.
Go round the refuge on the left-hand side or via the steel staircase and rejoin the yellow markings, which are in good condition. Head down this path. Pass the arboretum. Cross two ‘còrrecs’ (ridges). Make sure you close the electric fences properly. Take care when crossing the second ‘còrrec’; the path is very rutted and requires a degree of caution.

(9) Before the farm equipment storage building, near a set of weather stations, turn right onto a path and, after two sharp bends, join the D74.

Turn right onto this road and, 200 m further on, you will reach the car park (S/E).

Notes

Remember to download the map and GPX track: there is no mobile signal or data coverage from the La Llau car park.

Please note: from (1) to (7), the walk is off the marked trail.
This is a mid-mountain area. You will need: rainwear and a windbreaker, water, a packed lunch, the GPX track, route description, a map, the Visorando app or a GPS device, a camera, walking boots and a walking stick. Warm clothing is essential from the end of August onwards.
The weather changes quickly: on 30 December 2020, around midday, it started snowing as we arrived at the refuge. On 15 December 2024, there was snow on the ground and the temperature was extremely low (frozen ground).

Water is available at the refuge when it is open.

A winter area is available in the upper part of the Sant Guillem Refuge. Large room, no water, two large sleeping platforms without mattresses, very clean, door, skylight. Inaccessible when the refuge is open.
It is best to enquire to check whether it is accessible.

Worth a visit

This ascent to the refuge can also be considered during a stay at the refuge, as the standard route is short.
Sant Guillem Mountain Hut
Sud Canigó suggests a weekend in Sant Guillem in its guide sheets and route no. 24.

Very beautiful hike from La Llau to the refuge. Good meal. Perfect welcome. More direct return in 1 hour downhill on a single track.
A perfect Sunday with the family.

A very pleasant hike with varied landscapes between the climb to the refuge and the return to La Llau. Beautiful views over the Roussillon plain. Lovely beech and fir forests. A superb 50-metre-long sheepfold covered with Lauzes tiles, half-buried along the route, is a must-see. The stop at the San Guillem refuge... with Pauline's ever-welcoming hospitality, and a return trip through the arboretum, then along the path to the sound of the Coumelade river! Beautiful waterfalls and more superb beech trees. Highly recommended.

The information provided is accurate and precise, thanks to its author.
For (4): the grassy track is always perfectly maintained.
For (6): it could be added that you pass through a magnificent forest of fir and beech trees.
For (8): the forest crossing after the arboretum is very beautiful in December (ochre trees and grey rocks).

Aggressive barking in the hamlet at the start, but the rest offers a refreshing bath of greenery and calm when you come from the plains.
A very beautiful little hike!

Hello,
Overall, the route is pleasant. Along the way, you can see a stone sheepfold about 40 metres long, which is quite a rare design. The path that descends after the refuge, starting from the arboretum, is very pretty. We came across a rather tame chamois there.
A hike to be recommended.
Have a nice day.
