Best for
Over 230 Valais winemakers simultaneously open their cellar doors across Switzerland's most important wine region for a spring weekend every May. The Caves Ouvertes offers unprecedented access to producers normally not open to the public — from the Rhône Valley floor to high-altitude terraces producing Fendant, Johannisberg, and Cornalin. Free to enter most cellars, pay per glass. An authentic alternative to organised wine tours.
