The summit of Chiran, its astronomical observatory and its panoramic views of the Alpine peaks.

Located just opposite the Mourre de Chanier (highest point of the Regional Natural Park of Verdon, at 1 930m), Mount Chiran (1 905m), topped by its astronomical observatory, and its ascension are the highlights for a hiker. The particular geological formations in this sector have modeled remarkable landscapes. You will reach the alpine pastures and discover the traces of pastoralism throughout the hike.

3 points of interest

  • Flora

    A queen at the top

    On the slope of Chiran, go discover the Alpine Aster (Aster alpinus), also called the China Aster of the Alps.It is a perennial herbaceous plant of the Asteraceae family, genus of Aster. The Aster alpinus enjoys the sun on dry rocky lawns or in light-wooded areas. It may reach 3000m in altitude. It blooms from June to September.

  • Elevage et pastoralisme

    Salt and moutonesso

    On these pastures you may find what we call "assaliers", flat stones scattered on the grass. It is here, on these "lauses" (flagstones) that the shepherds lay the salt needed for the ovine. This salt is also useful to the shepherds, especially for the preparation of the moutounesso. It so happens sometimes that a sheep is hurt and it needs to be slaughtered. The flesh is then preserved in salt without a salting tub, in one piece, wrapped, dried for a week, then it is eaten plain or in soup.

  • Patrimony and history

    From the sheeps to the stars

    The Chiran is an imposing mountainous area settled at the edge of the Commune of Blieux. It had a pastoral mission for a long time, flocks from the lower Provence came there to graze the summer pastures. But now, since recent decades, Mount Chiran is famous for something else: the sky and the stars. The National Centre for Scientific Research in fact chose this place in 1967 for its upper-air and photometric qualities.


From the parking lot, head down to the village of Blieux for 200m until you reach a wooden sign saying "Portail de Blieux et Sommet du Chiran".

1 - Take the path on the right by a small concrete bridge. Five metres after the bridge, leave the main path leading to the house and take a small trail around it to the right. The climb begins quickly. In a short series of hairpin bends,you will discover the rare lavender fields of the pre-Alpine area. Continue climbing the path which can sometimes be steep, with multiple bends but occasionally flat, then around a corner, we can glimpsethe waterfalls of "la Clue". Pass along the right side of the canyon, after crossing several rocks. After this rocky landscape, pass, at the crest, the Robine canal before regaining further up some grazing areas. Follow the path, on a traverse, towards Portail de Blieux.

2 - At the mountain pass (Portail de Blieux, 1 620m),reach the track at the top and through it, reach the top of the Chiran (300m of elevation over 2.9km).

3 - At the top, a reading table will allow you to enjoy the panoramic views of the Alpine peaks. The same route is used for the return.
