R&R comes guilt-free at these eco-luxe resorts in Vienna, Paris, Ireland and Brittany.
IRELAND Head south of Dublin to Monart Destination Spa, one of the chicer retreats in the country, named by Condé Nast Traveler readers as one of the Top 3 in the world. Eco-cred: Green energy systems control heat and light in every room and biomass heating uses locally made wood chips to heat the hotel and keep energy use low. Water usage is reduced with low-flow showers and wind energy supplies most of the resort's electricity needs. Spa treatments use natural Pevonia Botanica products. Nature is also an important part of the relaxation here, and the surrounding 100 acres of woodland is incorporated into the experience. Food: Monart's restaurant focuses on local cuisine and has been recommended by the Michelin and Bridgestone guides. Who should go: Eco-hedonists.
