At the Col de la Griffoul, turn left coming from Brezons. A sign indicates whether the buron is open or closed. After 4 km on a motorable path in the mountain pastures amid magnificent views of the surrounding area, take a path on the right which indicates the buron. A meal at lunchtime or a drink during the day will be welcome.
The view is superb in good weather.
Discovery of the Granval cirque by continuing a few meters after the junction near the buron.
There is a sign.
