Col de Mazel and Pech de Therme from Col de Port

A beautiful hike with lovely views of the town of Foix and its castle, as well as the Pyrenees mountain range.
A very quiet hike, with unspoilt nature, shaded sections in the forest and sections exposed to the sun.

Description of the walk

Access the car park at Col de Port via the D618.

(S/E) From the Col de Port car park, take the track opposite, heading north-east, which winds its way through the ferns.GRP® Tour du Pic des Trois Seigneurs.

(1) At the top of this climb, you will arrive at Roc Blanc. Admire the Saurat valley and the Pyrenees mountain range.
Turn right, heading east, and begin an ascent through a grassy area where the path is not easy to follow. You may encounter herds of cows, horses or sheep.

(2) Continue on theGRP®, heading due east.

(3) At the signpost, turn left, heading north-east towards "La Devèze" and begin your descent through the rhododendrons.

(4) At the fork, continue straight ahead, leaving the GRP®. View in the distance of the town of Foix and its recognisable castle with its three towers. Pass the Cabane de la Devèze and enter a forest.

(5) Arrive at Col Mazel. Please note: this is not very well signposted. Take a forest track on the left, then left again. Look for the yellow markings (follow the IGN map).
After a long descent, cross the Baillés stream.

(6) From there, begin the climb towards Pech de Therme.

(7) Begin the second ascent. Pass the Cabane de la Trincade. Head for the summit. At 1570m, you will see the Orri de la Trincade and arrive at Pech de Therme.

(8) Admire the view! Continue descending to the right-southwest through the grassy fields towards the path you took on the way up.

(2) Join theGRP® trail opposite, following the same route as on the way up.

(1) Turn left and descend towards the Col de Port (S/E).

A superb autumn hike. The panoramic views are magnificent, and not just on the ridge trail. In the early morning light, the scorched ferns were stunning. I only encountered one local resident, with whom I had a pleasant chat.
The route description is very detailed, but a GPS is still extremely useful. Be careful before (7), you have to be vigilant not to continue on the forest track and at 7, you really have to watch out for the fork on the right. When you arrive at the open meadow, you have a beautiful view of the Foix valley, but it's a shame that the fir tree plantations are so straight (as is often the case, unfortunately), which spoils the pleasure a little.
As suggested in a comment, I continued along the GRP to the Fontanet rock and then returned via the left towards point (4). It was a bit marshy in places but no problem. This adds about 2.5 km.
As a result, at the end, the second climb seemed a little harder than the first. Even without this addition, it's quite a challenging hike: I recommend using walking poles!
Thank you for this suggestion.

A very beautiful hike with superb scenery.
No particular difficulties.
However, please note... At point 5 on the description sheet, at the Mazel pass, turn left onto the forest track marked by recent green markings on a white background...
And trust the route on the IGN map.

Given the date, the snow cover on the summit of Pech de Therme prevented us from completing the circular in its entirety. We therefore turned back at point 5. There is indeed a lack of signposting in the direction recommended by the Viso rando itinerary. We made a small cairn to make it easier to find the trail that climbs through the forest towards Pech de Therme

A beautiful hike with two ascents and descents, making it a bit challenging but accessible to all.
Too hot in July, even though we had enough water.
However, I wouldn't recommend it for those who are afraid of ticks (and rightly so!): I came back with three... Or do it outside of the fern season when they have grown back.
As for the route, follow the markers in the forest on the way back, or the GPS track, which is available from start to finish. There's no reason to get lost if you pay attention.
Thank you for the route.

A beautiful 6-hour hike from the Trincade hut to climb to point 8, Pech du Terme. Don't veer too far to the right and make sure you climb towards Pech; otherwise, it was a beautiful sunny day with no problems. Beautiful 360° view. To be repeated in reverse in the autumn.

A very pleasant route with views of Foix and Tarascon-sur-Ariège, I believe.
The first climb is well marked and avoids any major effort.
I started at point 3 on the Sarrat de la Pelade summit, climbing up the west side and descending the north side (descending directly north, you will find the descent trail on the left, which intersects with the trail at point 3 at the "col de la Devèze" signpost).
The entrance to the woods is to the left of the ridge (Cain and yellow marker).
This wood is very beautiful; I saw a deer nearby and smelled mushrooms.
At point 5, descend into the meadow and at the bottom you will find yourself at a crossroads. On the left, a path leads from the Devèze hut. Cross it to reach a track that starts there and descends gently to the left (yellow and green markings on a white background).
Just before the "ruisseau de ballés" (Ballés stream), mushroom hunters.
Leave the path at the "La Pastorale/Return to car park" signpost. At the first intersection, turn left, then about 300 metres further on, take a sharp right turn. There is a yellow marker on the ridge, then turn left and return.
Beautiful view of the Pyrenees mountain range with the iconic Mont Valier, which can be seen during the descent towards Massat.

Hello. This route was completed in foggy weather; the route was difficult because there are very few markings on the ground in some places, particularly between 7.8 and 2.

After a zigzag climb, the ascent levels out and offers magnificent views. We stopped at the hut for a picnic. We preferred to return by the same route to avoid the descent through the woods. We preferred to stay on the ridges

The hike took place in particularly mild weather for February, even though the wind picked up in the afternoon (I'll come back to that later).
Superb views and several nice places to stop (stream at point 6 for lunch with the frogs).
The route description is good, but I needed to use my GPS a few times. It should be possible to do without it, but you'll need to pay close attention.
As well as the warm-up at the start, you need to save your energy for the return journey. Your reserves are depleted between points 7 and 8, especially if it's windy. There's nowhere to shelter..

Great hike, great scenery
Did it out of season, so there were very few, if any, people on the trail
Some sections were not particularly easy due to the snow, but they could be easily avoided
The paths are not always easy to see, but you can see where you are starting from and where you need to go, so just aim for your destination
Otherwise, I recommend this hike. The beginning allows you to warm up, and after that it's pure joy
Superb views, a very pleasant stretch through the woods, a wide path and plenty of places to stop for a picnic

A real treat! The start is a bit tough, but you just need to take your time and you'll get through it. The rest of the hike is a walk alternating between ridges, undergrowth and plains, followed by a second climb that's also a bit tough, but the summit is well worth the effort!
However, I also made a mistake at point 5 (even though the author clearly mentioned it), and I continued along the forest track for a while before checking my GPS. That said, it's easy to cut through the undergrowth on the way down to reach a path that rejoins the trail heading south-west.
