Drive from La Toupine on the D951 towards Sisteron. Park at the small hamlet of la Baume, just before crossing the river bridge which leads into Sisteron itself. The lower flanks of the mountain consist of immense vertical sheets of rock which are very popular with climbers. Our path is just as strenuous but generates less adrenalin.

 

The path to the Trou d'Argent begins as the GR6 long-distance footpath, and a sign marked with red and white waymarks points the way just south of the bridge. A moderate climb through trees reveals views of Sisteron town below and the valley of the Durance stretching away to the south. Watch out for a yellow petit sentier waymark which bears left off the main path. The path then climbs steeply until it meets sheets of rock near the top of la Baume. The Trou d'Argent itself is reached with the aid of a steel cable.

 

To return, retrace your steps. If, when you reach the GR6 again, you decide to carry on to Entrepierres, be warned that during our last visit there in June 2000, the official path had been diverted and may no longer be available on the south side of la Baume.
