Park in the large car park on the left at the entrance to Chambezon.
(S/E) Take the small road, Rue des Acacias, opposite the car park. At the bend, keep left on the road and continue until you reach a T-junction. Turn right onto Rue du Ruisseau to reach a crossroads.
(1) Leave the road and turn right onto this track. Head uphill until you reach the edge of the woodland, turn right at the Y-junction and continue the steady climb until you reach the Caure plateau.
(2) Turn left onto the straight forest track. Note: after heavy rain, you may need to take the meadow to the right of the flooded track. Carry on until you reach the end of this plateau.
(3) Here, begin a fairly technical descent amongst the sharp rocks of the basalt flow. This descent is not slippery in dry weather but requires great caution in wet conditions. Then cross the Ruisseau de la Roche via a few planks. Join theGRP® Aux Marches du Cézallier, marked in yellow and red.
(4) Follow it to the left for just over a hundred metres, then leave it on the left to join the path running parallel to the railway line. Continue along this path until, much further on, you reach the edge of the forest.
(5) Carry on straight ahead until you reach the junction by a small cemetery.
(6) Turn right to go and see the rock shown in the photo; for details, see the explanation in the ‘Whilst…’ section.
(7) Return to the previous crossroads.
(6) Carry on to the right, entering Chambezon via Rue de l’Allagnon.
(8) Turn left to cross the Bourg neighbourhood and then return to the car park (S/E).
