Park in the car park at the southern tip of Lake Estaing.
(S/E) Take theGR®10trail marked in red and white, which starts at the side of the road and climbs up the hillside towards the Sapinière de l'Escale.
Cross an old track and climb a few metres further up the slope, which is still just as steep. Cross the forest track four times to reach the Arriousec hut in a small clearing, occupied in summer by a shepherd.
(1) The slope becomes less steep. A few metres further on, cross the track one last time after a short climb, leaving it behind you.
The route continues gently downhill through summer pastures, crossing two dry streams and, higher up, reaching the Garren stream.
(2) Cross it on a footbridge. At the foot of a fairly steep climb, broken up by small steps, reach the intersection ofthe GR®10and Lake Barbat.
(3) Turn right and walk 200 metres past the Barbat huts. From here, there are no more signposts, only cairns, to reach Lake Barbat, which takes 10 to 15 minutes.
(4) Return via the same route in the opposite direction to reach the car park where you started (S/E).
