(S/E) From the Pic P1 car park, walk past the eyewear factory to take a small path leading to the Pic P2 and P3 car parks (“Parking du Haut du Pic”). At the road, turn right to go round P3 and reach P2.
(1) Start on the rocky path that climbs (yellow markings) northwards to the foot of the peak through beautiful dry grasslands. At the Fork in the road, go straight on. A steep climb (white and red markings) leads to the Pic de l’Aigle.
(2) The path continues to the right, heading north-east as it winds along the wooded ridge. It comes close to a forest track twice and leads to the Belvédère des Trois Lacs viewpoint (Ilay, Grand Maclu and Petit Maclu).
(3) Follow a stony path, still hugging the ridge, which leads out into the fir trees at the Belvédère des Quatre Lacs viewpoint.
(4) The path climbs to the right to the Belvédère car park, below the Route Forestière du Bois de Ban. Follow the track to the left, which continues as a path, running alongside the ridge marked by clusters of cliffs without ever getting too close to it. Via a steep, winding descent – which can be slippery in wet weather – the path joins the D 75 at the Côte de Maclu.
(5) Take the cycle lane on the left at the side of the road (yellow markings) to reach Lac du Petit Maclu. Reach the lake by following the path to the left at the bend.
(6) Follow the path which then runs to the left of Lac du Petit Maclu and Lac du Grand Maclu towards Ilay. At the end of the Chemin des Lacs, the road on the left leads to Les Rousselets and its chapel, which seems to be nestled between two trees.
(7) Walk along the road to the left (marked with red and white signs) and take a path on the left which crosses the D39 twice – do so with care.
(8) After the second crossing, take the path furthest to the right opposite, then keep straight ahead and to the left. The well-marked path (an old tram line) climbs gradually up to the Chemin du Château. Then, at the junction between the forest road and the path you started on (yellow markings) towards P3, continue straight ahead to reach the car park from the outward journey (S/E).
