Follow the SS23 to the hamlet of Eaux-Rousses. Park in the car park at the junction by the Hostellerie du Paradis (signposted).
(S/E) Turn right onto the tarmac road leading to the hostel. Just before reaching it, turn right onto the path marked with a Yellow Triangle bearing the number 2. This is the Alta Via No. 2, which crosses the valleys running perpendicular to the Aosta Valley (see ‘Practical Information’ section).
Continue along this path through the woods until you reach an open area.
(1) Take a hairpin bend to re-enter the forest and reach the Roundzegou mountain pasture.
(2) Head back into the forest, then alternate between mountain pastures and woodland until you reach the wide, flat area of Orvieille. On the right, you’ll find the wide track leading up from the hamlet of Vers les Bois and the path leading to Punta di Bioula.
(3) Stay on the Via Alta No. 2 to the left, going round the Orvieille building. Follow a wide track to reach the large farm at Alpe Djouan.
(4) Here, begin a long traverse with a gentle, gradual climb. Head towards the green rocks at a place called Tramauil.
(5) Continue along this well-marked path to discover the very pretty Lac de Djouan behind a small hill.
(6) Retrace your steps along the route you took on the way out to return to the car park at Eaux-Rousses (S/E).
