The Embizon Pond

The Étang d’Embizon, well known to anglers, is much less frequented by hikers. It is true that the steep gradient at the end of the route, combined with long stretches without any signposting, may discourage some. And that is a great pity because, after the effort involved, this magnificent high-altitude lake is truly a reward of the highest order.

Description of the walk

Once in Savignac-les-Ormeaux, leave the N2020, pass between the police station and the school, and cross the very narrow bridge (take care) over the Ariège. Continue along the small tarmac road that passes under the Ax-les-Thermes bypass and then begins a series of tight hairpin bends as it climbs up the Ruisseau du Najar valley. Park on a grassy area at the side of the road near the few restored barns that mark the end of the tarmac road.

Excellent yellowPR® signposting

(S/E) Continue along the road, which immediately gives way to a wide track suitable for vehicles at a sign reading “No entry for all vehicles – Customs”. Cross an electric fence, taking care to close it properly behind you, and continue along the shaded track with the murmur of the Najar on your left.

The track leads to a small turning area with a sign reminding hikers of the correct behaviour to adopt in the mountain pastures. It then gives way to a wide, non-vehicular path that enters a magnificent beech and spruce wood. After crossing a second electric fence and several muddy sections where the stones on the ground prove very useful, you reach the Jasse des Esquers de Dessous and its hut.

(1) Cross this beautiful meadow by following the wooden posts bearing the yellowPR® markings, which prevent you from getting lost in very wet areas. After a few more muddy sections where you really have to navigate around the rocks on the ground, you’ll reach the Jasse des Esquers de Dessus (hut).

(2) No wooden posts this time, but the route is obvious if you head towards the valley floor. At the end of the meadow, rejoin the path that winds through the ferns. After crossing a few small rocky outcrops, you’ll reach a barely marked junction, indicated however by aPR® marker inviting you to head left towards the Pont du Ressec, which you can see a little further on.

Rare cairns

(3) Leave thePR® path, which continues south into the valley, and turn right onto a faint track that quickly becomes very difficult to spot on the leaf-covered ground. Climb straight up the slope, heading west, taking care not to stray from the Ruisseau des Pradels, which serves as a guide on your left.

Emerge from the woods to reach the Jasse des Pradels. Continue climbing for about fifty metres and veer left to get closer to the stream. Look out for a relatively small cairn on the opposite bank, which marks the spot where you need to cross.

(4) Cross the stream and follow a faint track that veers to the right, running alongside a small tributary of the Ruisseau des Pradels. After a few cairns over the first hundred metres, the track disappears and you must navigate the terrain as best you can between large boulders and clumps of rhododendrons, taking care to stay close to the stream on the right.

(5) Where the stream turns south-west, a clearer path reappears. Follow it, keeping the same direction. The magnificent Pic du Paillé towers above us on the right at 2,182m. Go round a small rocky outcrop on the left. The track splits into several paths due to livestock, so keep heading south-south-west, aiming for a saddle between two large rocks. Cross this to rejoin a well-marked path.

Cairns are much more numerous

(6) The route continues over gispet (a rock type characteristic of the siliceous high Pyrenees), which conceals numerous holes (some filled with water) that are treacherous for your ankles: proceed with caution! The slope steepens sharply and becomes challenging as you cross a succession of small rocky outcrops before easing off at the start of a grassy section.

(7) The trail becomes more or less lost again. Head for a small pass in the centre of the valley. The path, which you’ll find again a hundred metres further on, steepens once more before reaching the rocky cirque covered in scree that marks the valley floor (a small lake in the process of disappearing).

(8) Turn right to tackle the final ascent, first diagonally then straight up the slope, following a small stream flowing to the left at varying distances. Navigate this very steep slope as best you can to reach the pass that opens onto a vast grassy plateau housing a small, shallow lake overgrown with weeds. On the left, you can see the Embizon hut perched on a rocky outcrop (not shown on the IGN map).

(9) Follow a track through the grass on the right, heading north, which soon leads out above the Étang d’Embizon, nestled in its rocky cirque. Take in the beauty of the site and enjoy a well-deserved rest after all the effort of the climb, as the descent will be tough.

(10) The return journey follows the same route back to the barns where you started (S/E).

Notes

This difficult hike is intended for physically fit walkers with a good sense of direction and a good knowledge of the mountain environment. The route includes several off-trail sections and a third of the way is unmarked. There are cairns, but very few at the start, becoming more frequent towards the end.

Do not attempt this hike in foggy conditions, as this would make navigation very hazardous.

The majority of the elevation gain is concentrated in the final third of the hike. It is often steep and gruelling. This is particularly the case between (3) and (4), between (6) and (7), and between (8) and (9). It is advisable to take the necessary breaks.

Between (3) and (9), the GPS track corresponds to the route taken by the author. It is provided for guidance only, and each hiker may adapt their route. Several routes are possible; simply head along the valley, negotiating the difficult terrain as best you can and using the various torrents and streams to orientate yourself.

However, I would like to draw your attention to the following points:

  • Between (3) and (4): there is no clear path as the ground is covered in leaves. Keep the Pradels stream on your left as a guide and navigate the steep slope as best you can between the beech trees and large boulders. Once you reach the Jasse des Pradels, it is essential to spot the cairn on the other side of the stream, which marks the crossing point.
  • Between (4) and (5): the cairns disappear quickly. Keep the stream on your right as a guide.
  • Between (5) and (6): a well-marked path at the start, which then becomes much harder to follow due to livestock grazing. Several possible routes. In all cases, keep the valley axis and the stream on your right.
  • Between (6) and (8): route over scree. Many hidden holes and underlying water flow. Watch your ankles! Proceed with caution.
  • Between (8) and (9): the path is clearly defined at the start but becomes much harder to follow further on. No choice but to go straight up the slope.

Plenty of water along the route. However, the presence of livestock raises doubts as to its potability. Take sufficient supplies with you.

Shelter is available at the huts at Jasses d’Esquers Dessous and Dessus, provided the shepherd has not kept them locked.

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.

The trail is very difficult to follow in the forest, so a GPS is essential. Long, uninteresting trek through the forest. Beautiful view along the way. The pond is lovely.

A really lovely hike; the trail isn’t always clearly visible on the ground, but there’s no risk of getting lost. The end offers a stunning view of the lake and the surrounding peaks. Make sure to follow the GPX track closely.

An exceptional hike, though I can’t give it the full five stars because it’s tricky to follow the rarely used trail. You absolutely must download the GPS track to find this lake!

On the other hand, it’s incredibly wild, and the lake is really lovely! I started the hike much further down, and following the route until you leave the marked path is really straightforward!

A hike in the sunshine without seeing a single other hiker!
The path is very poorly marked (or non-existent) in places.
Ideally, download the route and use a GPS.
The hike starts off pleasantly in the forest along streams and, as the description says, there’s a steep climb towards the end.
For the return journey, we tried to take a shortcut by heading down to the end of the lake and following the stream: best avoided (boring, with dizzying and slippery sections).
