La Llagonne – Lac d’en Calvet – Pla de Barrès – Mont-Louis

This pleasant walk through the forest, along the banks of the Têt and through the fortifications is a summary of the walks in the Catalan Pyrenees that follow thePR®10,PR®19andPR®20. This route starts from the village of La Llagonne but could just as easily begin from the Citadel of Mont-Louis or Lac d’en Calvet.

Description of the walk

Start at the car park by La Llagonne town hall.

(S/E) Walk up Rue du Pré then follow the Promenade du Cambre d'Aze to the left until you reach the EDF transformer. Turn left and follow thePR®19signs. Turn left onto Rue d'En Tartes until you reach the riding centre. Continue along a path to reach the meadows and turn left onto a path through the woods.

(1) Turn right onto the path leading to Col del Mel.

(2) Turn left at the junction and join the D332 opposite a picnic area.

(3) Cross carefully and continue along the path opposite until you reach the ridge. Follow the track downhill to Pla de les Postes and continue straight on for about 200 m.

(4) Just before a fence, turn right onto a path leading to the small Lac de la Jasse de Calvet (Jaça d'en Calbet). Go round it on the left to reach a forest track.

(5) Turn left, cross a culvert and reach a junction of forest tracks. Ignore the one on the right leading to Bernardi and follow the one on the left. 100 m further on, at the next junction, continue straight ahead over undulating terrain.

(6) Leave thePR®19and go straight on, towards Route des Bouillouses and Mas de la Borde. Reach the access road to Lac des Bouillouses.

(7) Follow it to the right as far as the shuttle bus stop (in summer). Turn left and cross several log bridges and a bridge, following signs for Pla de Barrès. Just after the bridge, turn left onto a path that follows the banks of the Têt to another bridge leading to the Camping des Bouillouses.

(8) Do not cross this bridge but turn right, continuing along the banks of the Têt towards Mont-Louis.
Please note: at the time of writing, one of the signposts is rotated by 90° and points towards Mont-Louis in the wrong direction. After passing the sewage treatment plant on the opposite bank, join a forest track and follow it to the left to reach the D618.

(9) Without crossing the D618, immediately take the path leading down to the left, running alongside the waste collection centre gate. Continue to a tunnel that takes you under a bend in the road linking Mont-Louis to La Llagonne, and take this road

(10) Leave the “La Llagonne – Balcons de la Têt” path on your left and follow the Têt along the straight tarmac road leading to Mont-Louis.

(11) Take care and do not stray from the path from this point onwards, as the surrounding area is used as military training ground. Take the fortifications path on the left, below a building, and follow it round the Citadelle barracks. Observe the various training equipment used for commando training.

(12) Turn left to reach the junction of Rue du Foirail and Rue Mirabeau. Follow the latter, turn left to pass the post office and continue straight ahead to reach the South Gate. Leave the village walls and head towards the N116.

(13) Before reaching the road, turn right onto the continuation of the fortifications path running parallel to the N116, and return to the entrance to the military site.

(11) Turn left onto the small tarmac road, heading in the opposite direction to the way out.

(10) Continue straight on, following the signs for Les Balcons de la Têt – La Llagonne. Cross the small bridge over the Têt and follow the path until you reach the D118.

(14) Cross this main road carefully, follow it for a few metres to the right, then leave it by taking the path that heads left uphill towards La Llagonne. Pass the entrance to the cemetery on your right and join the Promenade du Pré de la Ville.

(15) Turn left, then left again to follow the Promenade du Cambre d'Aze, which you took at the start. Then turn right onto Rue du Pré to return to the town hall car park (S/E).

Notes

There are several ways to shorten the route:

  • At point (6), return to La Llagonne via thePR®19trail.
  • At point (10), return to La Llagonne without going around the Mont-Louis fortifications.

Upon entering the fortifications not far from (12), you will have a choice of several paths allowing you to view the upper (military) part and the lower (civilian, with its shops) part of the village of Mont-Louis.

Worth a visit

Three points of interest during this hike
(5) The small fishing lake at En Calvet.
The meanders of the Têt: Pla de Barrès.
The fortifications of Mont-Louis.

Completed in 3 hours in a hike-run format. The "Petit Canada" section is very busy, but the trails are quite wide and it's still very pretty! The first section is wilder and also very pleasant
This walk is very diverse in terms of the places it passes through (citadel, Têt valley, etc.) and is therefore enjoyable as well as easy.
Thank you

The Petit Canada section is very busy but very pretty. It's worth doing.
The combination with the tour of the citadel at Montlouis is nice and allows for a refreshing break!
Thank you for this route, which also offers a variety of walks in terms of elevation!

A lovely winter route, fairly easy. We found it a bit tricky to follow the route in "Little Canada", but we managed in the end. The first part is unspoilt and there are very few walkers!

Hello, Laurent. I don’t think there will be any particular difficulties if there’s snow; you might want to bring snowshoes along in that case.
