If you're looking for the most eco-friendly accommodations in California, you won't find them in LA or SF. Nestled in the heart of Napa, Bardessono is the only hotel in California to be LEED platinum certified thanks to its commitment to sustainability. 62 guest rooms are on-site — each designed for private in-room spa services — as are a restaurant and bar, a garden that provides food for the restaurant, a full-service spa, and a rooftop pool. It's fairly likely you didn't come there just to hide in the hotel, though, so its central location puts you within walking distance of a number of wineries, and literally hundreds no more than a short car ride away.
