Le Pla du Boum

This hike from Comus leads to Pla du Boum, at an altitude of 1,250 metres. This magnificent grassy basin, surrounded by forests of conifers and deciduous trees, is well worth the sustained effort required from the outset. The route alternates between wooded areas and open spaces where the Pic de Saint-Barthélémy, the Montagne de la Frau and the Château de Montségur are particularly striking. It can be done in any season but is recommended in autumn when the colours change.

Description of the walk

Arrive in Comus via the D20, the only possible road access. In the village, park in the car park in the courtyard of the old village school.

White and redGR® and yellowPR® markings

(S/E) Turn left when leaving the car park and reach the first three-way junction with a sign: No Entry for the middle road.

Yellow PR® markings

(1) Leave theGR® on your right and turn left, following the double sign: Boucle de Rouquières - Boucle Roc Rouge on the signpost. At the bench, leave the road and turn left onto a stony path.

About a hundred metres further on, turn left (marker on the ground) before reaching an enclosure for hunting dogs, which you can hear from a distance. The narrow path winds its way under the hazelnut trees, more or less parallel to the start with a double stony track, cuts across it and then rejoins it before leading to a meadow with cattle grazing on the left.

(2) Turn right at a wooden signpost, walk up the meadow, then enter the undergrowth. The slope is extremely steep and the elevation gain is sudden before you reach a welcome flat area and a crossroads with a signpost.

(3) Turn left, walk a few dozen metres, then keep to the right, following the direction: Circular Rouquières Bas - Col de la Gargante. The IGN map is not accurate at this point.
Join a forest track, which may be more or less rutted depending on the season, and follow it to the right, downhill to the Col de Gargante. Ignore the crossroads shown on the IGN map, as they no longer exist on the ground.

White and redGR® markings

(4) When you reach the pass where several piles of logs are stacked (situation in October 2021), turn left towards the sign indicating the Forêt Domaniale de Plaine Comus, which marks a three-way junction. Take the middle track opposite, marked Route des Sapins, and follow it along the contour line to the first right-hand bend.

(5) Here, you will find a very informative educational sign about the Frau Integral Biological Reserve and, a few metres further on, an exceptional viewpoint over the end of the Frau Gorges and the Aude plain. Perched on its rocky peak, the Cathar castle of Montségur is a magnificent landmark. Continue on to the Refuge des Gardes crossroads: an open hut with a table and fireplace, plus a picnic table outside.

(6) Opposite the refuge, turn left following the signposts, leaving another path on your left. Leave the forest, cross an electric fence and continue along the wide, flat path offering beautiful views on your left. Begin a descent into a vast open space where a solitary tree stands out easily.

No signposts

(7) At this point, leave theGR® and take a grassy path on the right that leads towards the forest, enters the undergrowth and further on comes out onto a forest track. Follow this track to the right until you reach a majestic tree with a sign saying: Chasse gardée (private hunting ground).

(8) Turn left onto a path that quickly begins a challenging climb and then descends to a carriage track.

(9) Turn left and follow it to the Col de Lancise.

(10) Turn right, pass the shelter hut on your right and keep right at the crossroads just after it. You will soon come to a fork in the road at a tree on the right with the number 49 painted in green on a white background.

YellowPR® markings

Turn left, following the sign for Tour du Boum on the signpost. Begin the gentle descent to Pla du Boum, a vast grassy basin surrounded by conifers which, as its name suggests, was once home to a lake (Boum = lake in the Pyrenees). Enjoy this peaceful site, which is reminiscent of Canadian landscapes.

(11) Shortly after a concrete watering trough, keep to the right and continue to the next junction where you will find a signpost with the following directions: Boucle de Montpié in the opposite direction and Tour du Boum on the right. Ignore both and continue straight ahead uphill. At the hairpin bend, turn right to follow the path that serves as a shortcut and leads to the Col du Boum, which is accessible by car.

Markings:GR® White and Red +PR® Yellow

(12) Go down the road opposite.

(13) Follow the path to the right, at a signpost, rejoin the road and cross it to take the path opposite. This becomes tarmac and leads to a crossroads where you turn left to return to the car park (S/E).

Notes

Good quality signposting. However, there is an error at (11), where a yellow cross on the edge of the path opposite could cause confusion. The yellow signposting continues at this point.

Do not miss the fork at (7). The solitary tree planted on the plateau is a very useful landmark. See photo.

The main effort of this hike is at the start, between (1) and (3), when you are cold. The elevation gain is 290 m over a distance of 1.3 km. The second difficulty is after (8) to reach the high point before starting the descent on the track (9).

There are no water sources on the route. Hiking boots are recommended. Depending on the season, there may be muddy sections between (3) and (4) and between (6) and (7). Forestry work does not help the situation. In this case, if there is no way around it, stick to the water channels where the rock is exposed and the current has deposited pebbles.

Possible shelters at:

  • (S/E) Covered courtyard of the old school.
  • (6) Refuge des Gardes: table and fireplace. No low wall or water source.

The other huts at Col de la Gargante and Col de Lancise were closed when I visited (October 2021).

Picnic table and stone structure for making a fire at (4), (6) and (10).

Worth a visit

Particularly harmonious mid-mountain landscape with forests and meadows. A remarkable site in autumn when the deciduous trees change colour, or in winter under the snow.

(5) Educational panel and viewpoint.

(11) Pla du Boum: large basin surrounded by beautiful spruce and deciduous forests. A little taste of Canada. Ideal spot for snowshoeing.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

Very nice circular, not very busy on this mid-April weekend.
The climb between 2 and 3 is indeed quite steep.
The track between 8 and 9 is not necessarily obvious as it merges with forestry tracks. GPS is very useful!
I recommend doing the circular in the direction indicated because Pla de Boum is the reward at the end of the route and it is prettier when crossing it in this direction.
The route is varied, alternating between trails, tracks, forest paths, forests and clearings...
And there are some very pretty views along the way of Montsegur, the Black Mountain, etc.
The description is very accurate.
Thank you for sharing this route.

I hiked part of this route a few years ago, taking a shorter route (parking my car at the Col de la Gargante, point 4, and returning via the Pla du Boum trail, elevation 1,266 metres, after point 11): it's already a beautiful route, taking 2 hours and 15 minutes to walk with a total elevation gain of 350 metres. Perfect for warming up.
On this section, the main attraction (apart from Pla du Boum, which gives the hike its name) is the bird's-eye view from "Pas de l'Ours" point 5.
I do not recommend this hike in summer, as it gets very hot in the Pla du Boum basin. Spring (with beautiful views of the snow-capped peaks) and autumn are better times to hike.

A beautiful hike through woods and meadows, sometimes with herds of animals. A bit busy on the GR section (Cathar trail).

Hello,
A magnificent hike along the entire Sarrat de Rouquières trail. The view of the plain and the Montagne Noire in the distance is superb.
Beautiful view of Montségur. The Pla de Boum is splendid. Nothing but praise.
Thank you.

A very beautiful hike completed on 9/07/2022. The explanations are reliable and well explained. Be careful, however, between 8 and 9, as the trail tends to disappear under the vegetation. Otherwise, a beautiful, challenging hike that I highly recommend.

Route completed on Wednesday 27 October in cool, sunny weather, with a detour to Sarrat de Rouquières from Comus, offering magnificent views of the Ariège mountains, as well as a detour via the mountain passes and the beautiful circular Séména above Camurac.
Magnificent view of the Frau Gorges at Pas de l'Ours.
The Gardes and Lancise mountain huts are open to hikers, while the Gargante hut is closed.
The detailed map is very useful, especially on the unmarked sections of the trail.
Duration: 7 hours 10 minutes.

A superb, well-described mid-mountain hike. It allows us to better discover the riches of this beautiful county as well as the so-called "Canadian" part. A big thank you to Jean Pierre for sharing this wonderful experience with us. Best regards to all.
