Gréolières is about 40 kilometres northwest of Nice airport and the drive takes 45 to 55 minutes in normal conditions. From Nice, take the A8 motorway west to Cagnes-sur-Mer or Villeneuve-Loubet, then head north on the D2 through Vence and Saint-Paul-de-Vence, continuing on the D2 to Coursegoules and then Gréolières. The final stretch on the D2 above Coursegoules is a narrow mountain road with hairpin bends — manageable at ordinary speeds but not the place to be in a hurry.
There is no rail connection. Bus service is limited: the Lignes d'Azur network runs infrequent services from Vence, but the schedules are not designed for day visitors and the last bus back to the coast can be early. A car is the practical way to visit, and the drive through the Loup valley and up through Vence is a good one in its own right. From Grasse, the approach via the Gorges du Loup and Gourdon is longer but more spectacular.
