Housed in a range of what were originally farm structures, Carneros rocks a kind of sustainably-minded agricultural chic. The spa carries this theme, with earthy natural ingredients, as does its lounge-style restaurant, The Farm. An infinity pool provides a wonderful spot to soak in the countryside (it’s adults-only, so you can enjoy some peace and quiet – there’s another pool for families). Choose to stay in one of 86 cottages on-site, all with their own gardens, patios and decks with gas heaters and outdoor showers.
