The Potato Gastronomic Festival Activity · Vilar de Barrio, Limia, Ourense Image of Vilar de Barrio, not of the place itself. Each October the concello devotes its great festival to the newly lifted potato, cooked as cachelos, in stews and in omelettes. It is held at more than six hundred metres of altitude, in the transition between A Limia and the Serra de San Mamede. octubre Photo: Elisardojm (CC BY-SA 4.0) What to see and do in Vilar de Barrio
