(S) From the Eylie stopover lodge, head towards the signposts and cross the Ruisseau de Rouge.
(1) Turn right and, further down, join the access road to the hamlet. Head up the road to the left and reach the final hairpin bend. Signpost.
Recentyellow PR®markings
(2) Continue straight ahead, due north, starting on almost flat ground in the forest. After a left-hand bend, begin a steep climb, heading north-west. Pass under the EDF water pipe and arrive at a fork.
(3) Continue left on the PR® in the same direction. Continue the steep climb to another fork (alt. 1120 m). Signpost for Col de Cos.
(4) Please note: there is some old yellow signposting which may be misleading. Follow the recent yellow signposting (August 2023) carefully.
First turn right then left and continue up a less steep slope. Curve to the left, heading south-west.
The path descends to the right, towards the stream (Ruisseau de Haurendech), which is flowing strongly (August 2023).
No footbridge. The crossing of the stream indicated by the yellow markings was impassable on this date.
Look for a crossing further up where the stream has not yet split.
(5) Cross it as best you can and continue on the other bank heading north. From this point, on several occasions, you will need to pass through trees across the path. Keep a close eye out for and follow the very clear yellow markings. Cross the Ruisseau de l’Alléo and emerge from the forest towards the 1286m mark.
Beautiful views over the many small hamlets.
(6) Continue the climb westwards on a very good path that is clearly marked on the ground and well signposted.
You’ll reach a vast area of summer pastures and a junction with several paths.
(7) To the right, Cabanes de Cos. One, in very good condition (new roof), is freely accessible. Another hut, belonging to the shepherd(s), next to it is fully equipped and in perfect condition. Continue straight on towards the water source and follow the wooden fence. Reach the Col des Cos. Directional sign screwed onto the fence.
(8) Continue downhill along the PR®, which is well signposted, marked on the ground and heads west. After a pleasant descent, join the GRP® Tour du Biros.
(9) Descend a few hairpin bends, then turn right onto a wide path, which is very muddy in places and marshy. Much further down, you’ll reach the Passerelle des Pichès (alt. 1,130 m).
(10) Without crossing it, continue straight ahead on the GRP® and, further down, you’ll reach the Passerelle Illa Maria.
(11) Cross it and head right until you reach the junction at elevation 873.
(12) Leave the GRP® to your left. Head down to the right onto the GRP® access path and arrive at the end of the road.
(13) Continue left, still on the GRP® access path towards Anglade. Reach a fork. Directional signs. Turn right and arrive at the Anglade car park (E).
End of the three-day Petit Tour du Biros.
