From Seix, head towards Couflens on the D8F, then turn right at Moulin Lauga. Follow this small road to the hamlet of Estours. Pass the hamlet below you and cross a bridge. We left the car in a lay-by just after the bridge, but there are other places to park further along the track.
(S/E) Follow the track that runs alongside the River Estours to an EDF building and signposts.
(1) Carry on straight ahead, towards the Cascade d’Arcouzan, along a wide path through the woodland. Gradually, the path climbs and turns into a footpath.
(2) The path overlooks the river, which you can hear roaring below in the gorges. Further on, you’ll get closer to the river as the valley widens.
(3) The woodland gives way to a young beech forest. Further on, gaps in the trees reveal the steep peaks that line the valley. The path stays close to the river.
(4) The valley narrows once more. Finally, you emerge from the woods onto a meadow, bordered on all sides by high cliffs.
(5) To the right is the Arcouzan Waterfall. Continue along theGR®® to the far end of the meadow, then climb a few hairpin bends through the Bois du Puech d’Aula to a first bridge.
(6) It offers a lovely view of the meadow below; carry on to reach a second bridge: these two footbridges span beautiful streams that form waterfalls in the Artigue.
The return to the car park (S/E) follows the same route as the outward journey.
. This might be the case again next year(s). Parking is now at "Aire de Moulin Lauga" which does add quite some kilometers to the walk.
