North of the Etang de Thau, this loop takes you to the Gallo-Roman site of Marinesque and the Via Domitiana, before crossing the garrigues and forest of the collines de la Moure. The route then reaches Lac de Cambelliès, a former bauxite mine turned bird sanctuary, before returning to Loupian through vineyards and garrigues, with beautiful panoramic views over the Thau lagoon.
