The waymarked path, which must not be left at any point, climbs through a wooded coomb, where a rocky head standing out above the trees becomes visible to the left. As you go along the path that follows the line of the ridge and head down towards the pass, the "Trou de la Bombe" comes into view. This is a naturally formed hole about 8m in diameter in the ridge of the Paliri mountains, located to the right of the Calanca Murata and before the Campanile de Ste-Lucie.
