The Étangs de Bassiès from Massada

First day of a three-day trip (August 2023) starting from Vicdessos (Val de Sos).
Please note: the suggested route, which is in excellent condition, is only sparsely signposted, except for the section of theGR®®10.
This hike is classified as difficult due to the need for a good sense of direction, the poor condition of theGR®®10, the numerous steps to negotiate, the duration, etc.
If it is simply a return trip to the refuge via theGR®®10, then the walk can be classified as moderate.
=> August 2026: access to the lakes and the refuge may be affected by this => GR®10 in Ariège: Temporary closure of the Marc > Port de Saleix section (diversion)
It should be possible to do a return trip to the lakes and the refuge via the power station (6) without returning via the GR®10!

This walk is part of a multi-day hike: Séjour de trois jours en Val de Sos

Description of the walk

From Vicdessos, head towards Auzat via the D8. Pass through Auzat, then continue towards Marc on the D8. A little further on, pass Astiès on the left and stay on the D8. You’ll reach a large car park on the right (Aire de Massada) just before a double hairpin bend in the road.

(S/E) From the car park (elevation 821), continue uphill along the D8, behind the safety barrier, until you reach the first hairpin bend. Signpost.

(1) Turn right, heading towards the Bassiès refuge. Cross the lovely footbridge and turn left as you climb. You’ll soon reach a junction with a path on the right.

(2) Ignore this return path on your right, marked with a large orange arrow. Carry on straight ahead, uphill. Take care: risk of slipping, as the path is waterlogged. Continue uphill until you reach another inconspicuous junction with the return path (alt. 990 m).

(3) Ignore this return path on your right. Carry on straight ahead, climbing. You will eventually come out onto the access road to EDF’s small Bassiès power station.

(4) Cross the road and continue uphill opposite along a rough track. Further on, you will emerge at a large crossroads where four paths meet.

Old, very sparseyellow markings

(5) Ignore the two successive paths on the left (GR®®10coming from Mounicou and heading towards Bassiès).
Carry on to the right, due east, along a paved path over an old aqueduct. A magnificent path running like a balcony along the mountainside. Cross the Bassiès stream, which is channelled by the power station. Cross the various footbridges and secure grating sections of the EDF structure and arrive at the end of the road.
Walk along it for about 70 metres and look out for a very good path on the left (alt. 1,150 m).

(6) Climb the switchbacks along this magnificent stony path. Stunning scenery. After a steep but beautiful ascent, you’ll reach a vast summer pasture and a flat area at an elevation of 1,586 metres.

Red and white markings forthe GR®®10

(7) Continue straight on along theGR®®10. Walk alongside the Étang d’Escalès, the Étang Long, the Étang Majeur and the Étang du Pla de la Font, and you’ll soon reach a fork in the path. Directional signs.

(8) Turn left and walk along a long wooden boardwalk. You’ll come to a fence and a gate on the left.

(9) Go through the gate and head up to the Refuge de Bassiès (altitude 1,654 m), going round it to the left

(10) A spacious area with the start of several hiking trails, including the mandatoryGR®®10route, etc. Beautiful scenery.
After a refreshing break, turn back towards the gate.

Red and white markings ofthe GR®®10

(9) Head straight on and climb a little until you reach a fork in the path (alt. 1,660 m).

Old, very sparseyellow markings and remnants of red and white markings.

(11) Let theGR®®10branch off to the left. Turn sharply right and head for the Étang du Pla de la Font and the fork you passed on the way out. Directional signs.

White and red markings ofthe GR®®10

(8) Continue along theGR®®10, in the opposite direction to the outward journey, until you reach the junction, which you also passed on the way out (elevation 1,586).

(7) Carry on to the right along theGR®®10, crossing the self-supporting stone arch bridge. Follow the badly worn path through numerous hairpin bends to reach the four-way junction from the outward journey.

Old, very sparseyellow markings

(5) After a quick right-left turn, continue downhill along theGR®®10, in the opposite direction to the outward journey. You’ll reach the access road to the EDF power station.

(4) Cross the road and reach the second junction you passed on the way out.

No signposting

(3) If in doubt at this junction, continue downhill in the opposite direction to the outward journey.
Otherwise, turn left into the forest, heading due east, along a clear, attractive path which avoids the entire slippery section. After a few hairpin bends, turn right heading due east (the end of the recorded track is accurate and does not correspond to the IGN map). Join the path taken on the way up.

Old, very sparseyellow markings

(2) Head left and, following the route in the opposite direction to the outward journey, return to the (S/E).

A lovely walk; most of the ascent is in the shade of the forest
The final hour’s walk to the mountain hut is in the open, alongside the ponds
The descent on the way back is a bit long and tiring because of the loose stones underfoot
Very peaceful and with a beautiful view once you reach the top above the refuge

A very beautiful hike done on a hot day. Much of the climb is in the shade, which makes it easier.
No trouble following the path; I think the signposting has been redone.
Swimming in the main lake at the dam (easy access via gently sloping rocks). Great day!

Great hike! Quite challenging. 1½ hour climb
Small correction at the start of the hike after the bridge: when you reach the post, turn right onto the rocks and then it climbs...

Thank you, Visorando.

Taken on a beautiful day, this hike was splendid. The climb is steady. Not too crowded despite the season. And the temperature of the first lake (Escalès) was pleasant for a quick dip. The Bassiès refuge accepts credit cards.

Hello,
you will need a map. Follow the markers (a few cairns) carefully. The climb is steep and practically all at once until you reach the footbridge before the ponds.
