Sion’s vineyards are well irrigated by three bisses (irrigation channels) and three hiking paths follow these. They have a very gentle gradient, go through several interesting and pittoresque areas, with educational panels that guide you through the sensory delights of the natural wonders and vineyards here. You’ll also find a good deal of information on the work in the vines, the region’s wine producers and grape varieties…
