2. For getting around the Faugeres region from village and village around Caussi, up into the mountains and so forth, Michelin Local Map 339 Gard Herault 1/200,000 is fabulous. You'll find your way on that beautiful back road from Faugeres to Pezenas, past several vineyards and a castle without problem, for example. Or see exactly how to climb up to Douch to start the walk to Mt. Caroux.
