For those who'd like to ensure that personal relaxation doesn't have an adverse effect on the environment, Luxist's best green spa nominees offer the best of both worlds. The freshly minted Bardessono in Yountville, Calif., is one of the top options.

Founded in February of 2009, Bardessono is the product of a wealth of time and experience that belies its young age. The Napa Valley retreat was conceived by Phil Sherburne, a former Seattle city planner and son of organic dairy farmers. Now a conscientious developer, Sherburne brought Seattle architect Ron Mitchell on board to design the sustainable 62-room hotel. The resort practices green building and operating practices. It is heated and cooled by underground geothermal heating and cooling system. The hotel is powered almost entirely by its 940 rooftop solar panels.

Every room at Bardessono is designed as an environment-friendly personal spa, from the locally sourced stone and salvaged woods to the organic food, bedding and even cleaning supplies. Spa Suites offer an open living space and generous amounts of natural light with a luxurious bathroom, gas fireplace and a private courtyard. The custom bathroom, designed to double as a private spa, features a concealed massage table, a soaking tub, separate shower, and double vanity. The Spa Therapy Center offers rooms for couples' massages and facials. The saunas are equipped with a far-infrared sauna for the ultimate purification.

Specific in-room massages range from the 60-minute Vinotherapie Massage ($125), where your skin will be rejuvenated with organic Chardonnay grape seed oil, to the 120-minute Soothing Warm Stone Massage ($280), complete with river-worn stones applied by an experienced therapist. What better way to relax body, mind and conscience.

To use the words of a Luxist reader: "The resort is beautiful, the accommodations outstanding and the personnel very professional---and it is all green!"
