Tierra Atacama aims to pamper guests without harming the terrain of this high-altitude oasis. Desert breezes cool the adobe-and-stone buildings, and water is drawn from a well. The 32 rooms feature alfresco showers and floors made with crushed seashells; some have four-poster beds and open onto patios roofed with bamboo. Gardeners tend to ten acres of native quinoa, corn, and herbs fertilized by compost, irrigated by snowmelt, and ultimately used in the kitchen. The service at the hotel is personalized and warm—staff surprise birthday-celebrating guests with cake and champagne. Those on all-inclusive packages can summit volcanoes, visit flamingo-filled salt lakes, or explore flora-carpeted canyons. The less energetic get little farther than the imaginative spa, the bar fashioned from recycled oak railroad ties, and the cushion-scattered terrace, where flaming torches ward off the evening chill.
