Approach notes

Park at the Point de l'observatoire then cross over and take the tarmac DFCI track which curves round. After 10-15 minutes look for a cairn on the right - just before the pilier de feu sacré comes into view and teh DFCI track curves right. Take this little path and stomp up a rock scree section to join a horiwxontal path (which perhaps you can come in on if you stay on the DFCI track a lit longer). Follow this to the right until your just below the crag, at an area of scree. NB its not the first couple of buttresses you see but the bigger one to the right.
