The speed camera in Périllos

Loop hike to reach the Montoulieu-Perillos weather radar. From the village of Perillos (abandoned village), easy hike on a stony path (emergency access) (beware, no shade) to the radar, but the descent is more difficult.

You can park near the Sainte Barbe chapel (point 11) to avoid having to climb back up to the village at the end of the hike, but the village is also well worth a visit.

Description of the walk

Park in the car park in the village of Périllos (municipality of Opoul-Perillos). Park at the top of the village (dead end).

(S/E) Go back down the road. Wind your way through the village streets, then take the road that descends from the village for 400 metres until you reach the intersection.

(1) Turn left onto the path that turns almost 180°. Follow the cistern and continue to a new crossroads.

(2) Take the road on the right that goes uphill. After passing a barrier prohibiting vehicle traffic, follow the path to the top. Cross several streams and reach a hairpin bend under the Serra de la Gran Cremada.

(3) Continue east-northeast. On the ridge, you will see boundary markers (department boundaries?) before reaching the speed camera.

(4) Radar: ideal for a picnic spot.
To return, take the path that runs along the right-hand side of the speed camera, slightly below it, until you reach the high-voltage line.

(5) Be careful, from here on, it is very difficult to find your way (there are lots of cairns, don't miss the three cairns side by side). When you are under the high-voltage line, turn left for 20 metres to find the first cairn. Follow the others along a small, very stony path that descends. You will reach THREE cairns next to each other.

(6) Take the path that descends to the right. Be careful, there are cairns everywhere.
The path is steeper and narrower. Continue along this path, heading south at first, and cross the Coma del Remoli valley at the high-voltage power line. Head south-east, leaving the forest to join the Coma del Cabrit track.

(7) Take it on the right, cross the Ruisseau des Abelles (dry?) and reach a crossroads with four trails.

(8) Take the right-hand trail and you will soon reach another crossroads with a ruined sheepfold.

(9) Turn right again and follow the cairns to reach the Grotte de la Cauna, which is located next to cypress trees that stand out in this heath landscape.

(10) Take the path again (very difficult to see, however, among the rocks). Make a U-turn north of the cave and head west.
Follow the dry stream bed to come out at the bottom of a field and find a path that leads to the Santa Barbara Chapel.

(11) Continue until you reach the road leading to Périllos. Follow it to the right (it winds) to reach the crossroads of the loop after 2 km on the tarmac.

(1) Turn left to return to the Périllos car park (S/E).

Notes

To get to Périllos, go to the village of Opoul-Perillos and follow the tiny sign for Périllos.
Be careful, as you will then have about ten kilometres without any signs on a road where it can be difficult to pass other vehicles: drive carefully.
The path is unshaded but climbs steadily.
There are no inhabitants in Périllos. Just vegetable gardens tended by workers restoring some of the houses.
There is no water.

The hike is not marked.
There are numerous cairns on the descent to confuse you. A GPS will be very useful.
GPS track recorded on the map and not during the hike: the section after the speed camera is approximate (no trail on the map).

Worth a visit

Salvaterra Castle (Opoul-Perillos), Salses Pond.
Cauna Cave.
Périllos weather radar.

To avoid returning on the tarmac, you can leave a car in front of the Santa Barbara Chapel or start from there.
But don't forget to visit this abandoned but restored village!

A hike with beautiful sea/mountain views. Choose a period that is not too sunny, as there is little shade along the way. The descent in 6 is easy to find. The cave at 10 (popular as it is easily accessible without doing the hike) is a pleasant surprise at the end of the route.

The section beyond the radar is tricky: you can quickly find yourself off course, but with the app you can find your way back...
Not a route to do in the heat of the day

In my comments in 2022, I mentioned a variation that cuts off about half of the trail, which I recommend to experienced hikers:
"After Périllos and at the start of the track leading up to the speed camera, take a path for experienced walkers opposite the cistern. It is marked with cairns and dark green signs until you rejoin the track quite high up, which avoids the long climb up the track."

The descent is much more enjoyable as it is varied and surrounded by nature. The climb is too long. The cave is magical: a must-see if you are staying in the area (the colours and formations of all shapes and sizes make it unique for a freely accessible cave).
No problems following the route with GPX.

Easy hike to follow with the app, beautiful views in the first part of the hike of the snow-capped Pyrenees
and the ponds, with the karstic cave of Cauna being of particular interest.

A very pleasant route, with the return journey being more picturesque than the climb up the wide path towards the radar station. We had some difficulty finding the cave, but it was well worth the effort. Thank you to the author.

We followed the hike using GPS tracking. Luckily, because we missed the turn at point 6. The path had been cleared and marked with red and white tape. Confident, we stayed on the track and missed the path. The markings are then a green circle to follow downhill. There is a little shade only in this small section of the descent through the boxwood trees.

Every year, I do this route a little differently... After Périllos and at the start of the track leading up to the speed camera, there is a trail for experienced hikers opposite the cistern. It is marked with cairns and dark green signs until you rejoin the track quite high up, which avoids the long climb up the track.
For the descent, follow the various markers of different colours (yellow, green and red) until you reach the three cairns, one of which is enormous, about 70 cm high (and growing every year!). Here, be careful to keep to the right on a path that is not very well marked at first but becomes much clearer after a while, leading you without any problems to the track down in the valley. It has recently been re-marked in dark green.

Nice hike, the descent is a bit tricky, use GPS in some places. The trail near the La Cauna cave
is quite difficult to find. You have to go over the cave and look for the trail that leads back to the chapel.
Otherwise, there are beautiful views of the lake and the surrounding peaks. The cave is worth seeing. There were a lot of people at the cave.

I went on a hike yesterday with my partner without any problems. It's true that the "road" isn't the most pleasant (pebbles), but it's very well marked on the ground. It's a shame, however, that there isn't a sign pointing the way to the cave!
