6 Best Day Trips from Paris

"This estate is one of a few in Champagne to have crayères, chalk caves that began as quarries in the Early Middle Ages and are ranked a UNESCO World Heritage Site. The tour itself, which is only available upon request, with reservation, and with a guide (in English or French), takes a sizable group (10 to 12) into the Gallo-Roman crayères. Most cellar visits are relatively straight forward, but the Pommery visit is punctuated by contemporary art installed throughout the tunnels and galleries as temporary exhibitions. This is an excellent tour for anyone visiting Champagne who knows little about the region, Champagne production, and even less about the crayères. It's an engaging visit that ends with a tasting." - Lindsey Tramuta, Mary Winston Nicklin
