Head to Lake Guéry and park in the large car park at the far end of the lake.
(S/E) Take theGR®®30(red and white markings). N.B. Contrary to what is shown on the IGN map, thisGR®® now runs along the right-hand bank of the lake to avoid the road.
(1) Stay on the well-markedGR®® trail which, after following a track due south at the end of the lake, turns west. Walk through the mountain pasture before beginning the ascent of Puy Gros. Reach the summit of this Puy.
(2) Then descend to the hamlet known as Le Tenon, where there is a sign reading: ‘Au Vieux Loup’.
(3) Leave theGR®® here and take thePR®® (yellow markings), which crosses the pastures to join a wide track at the Col de Saint-Laurent.
(4) Turn left to reach the summit of the Banne d’Ordanche via the wooden steps.
(5) Return to the aforementioned junction at the Col Saint-Laurent.
(4) Continue along the track, heading east then north-east. Pass through the ruins of the Puy May farm.
(6) Join the nature trail which leads back to the first junction.
(1) Follow the route you took on the way out in the opposite direction to return to the car park (S/E).
