A gorgeous boutique property spread over six acres in the charming town of Yountville in California's wine country, this hotel defines high-end luxury. But that is not how it's making its mark. One of the few LEED-certified Platinum hotels in the world, Bardessono is positioning itself as a leader in sustainable practices. Its effort began right at the start, when salvaged stone and reclaimed wood were used in the construction. As well, an underground geothermal system was added for heating and cooling, and more than 900 solar panels meet nearly all of the hotel's energy demands. Sure we love the rooftop lap pool, sumptuous spa and 62 plush guest rooms, but what makes a stay here so satisfying is the unwavering commitment to making the world a better place, from partnerships with local artisans to its Lucy Restaurant and Bar, serving farm fresh, locally sourced, organic cuisine.
