If you’re mostly in it for the wine, there are tastings, tours, and winemaking experiences in abundance across the trail’s environmentally diverse landscape. At Grotte Saint-Marcel, you can venture into a 490-foot (150 m) stone tunnel that’s been converted into a cellar for aging Syrah, Roussanne, Marsanne, and Viognier, or join a blind-tasting of southern Ardèche wines 330 feet (100 m) underground. At Domaine de Montine in Grignan, wine tasting, and tours of the cellar and vineyards are run alongside seasonal truffle hunting experiences and visits to the nearby Richerences Truffle Market.
