Take the D3 towards Col Lebraut. The route starts at the ONF marker at Clot des Marelles: there is a small car park opposite, at the side of the road, which is shaded in the morning.
(S/E) Cross the D3 carefully and take the path opposite. You’ll reach a junction about fifty metres further on: there’s a signpost there.
(1) Turn left towards Serre Cocu, walk for about a hundred metres, then take the path on the right. Walk through a deciduous forest, then a coniferous forest. You’ll reach a climb amongst the slate outcrops: a lovely view of Lake Serre Ponçon.
(2) Continue along the path, keeping uphill.
(3) At the Clot Chauvin signpost, head towards Le Fein, to the right.
(4) At the crossroads, follow the path on the right that leads downhill. You’ll then enjoy some lovely views of the Chorges mountains.
(5) At the Clot Minet signpost, carry on straight ahead to head back towards Clot des Marelles.
(1) Keep to the left to return to the D3; cross it, taking the same care, to reach the car park opposite (S/E).
