The majority of the Château des Gavelles vines are situated on the Puyricard plateau, on the southern foothills of the Trévaresse hills, a small chain in the Provencal inland, linking the Alpilles to the Montagne Sainte Victoire.
It is one of the most remarkable terroirs of Provence, by virtue of its size, fertility, climate and the memories it evokes.
 
It is dominated by a large forest of Holm oaks, kermes oaks, umbrella pines, European hackberries, cypress trees and cedar trees. For centuries, vines, wheat, olives and more recently, almonds and blackberries have been cultivated on these stony, clayey-chalky soils, of Miocene origin. A wide stream, the Touloubre, runs across the plateau from east to west, providing water and coolness to the crops.
 
The altitude of 300 metres endows it with a healthy harsh climate, very different to that which reins over the Mediterranean coast, 29 km away as the crow flies. The summers are hot and dry with a good daily temperature range (cool nights). The winters are cold and it is not rare for temperatures to go below – 10°C. This terroir is particularly interesting for the production of excellent reds and concerning the whites, the Rolle (Vermentino), a late ripening varietal, flourishes in these conditions.
 
The cold and dry Mistral wind, one of the main factors of the Provencal climate, has contributed over time, to sculpting the local ecology and agriculture. It contributes to maintaining an exceptionally healthy climate which is important for viticulture and the production of quality wines.
