China’s population may be booming and the country’s cities increasingly more polluted, but there’s fresh air in sight for smart travelers: a bona-fide eco-resort. Deep within the Nankun Mountain Reserve, 2½ hours northeast of Hong Kong, the architectural-award-winning Crosswaters Ecolodge & Spa (86-752/769-3666; doubles from $300) has 49 feng-shui’d villas and suites—each constructed of indigenous bamboo and appointed with organic local textiles—strung along a riverbank with cinematic mountain views. When guests aren’t being pampered with acupuncture and herbal massage treatments in the open-air spa suites, they can bone up on regional wine-making techniques or practice tai chi in a studio shrouded by forest—ideal for clearing the mind (and the lungs) after a sojourn in one of those hazy capitals.
