Approach notes

From Foix, take the D1 towards Lavelanet. After around 15km, take a left towards the hameau (hamlet) of Garrigue. The road winds steeply up through the village and shortly after leaving the buildings take a sharp turn to the left, a right fork here runs towards some large agricultural buildings. The gravel track then leads to parking for about 4 cars on a right-hand bend after around 250m.

Locate the narrow path on the outside of the bend and zigzag up through woods on a slightly overgrown track to reach the limestone ridge. Follow pink splodges and cairns leftwards, initially through the trees, and then along the exposed rocky ridge. A scrambly section (easiest just to the left of the crest) leads to a short scramble down to a flat rock ledge (do not descend too early - if in doubt follow the pink spots). 12m along the ledge, the path jigs right (pink arrow) to enter a channel. Descend this to find an impressive leaning fin of yellow-and-grey rock punctuated with cracks. Loop round left to reach the base of the wall.
