After a two-hour motorized canoe ride down the Napo River, followed by a half-hour hike on a jungle-lined boardwalk plus a dugout-canoe crossing of Garzacocha Lake, guests are greeted at La Selva with cold towels, snacks, and juices. They're then shown to cheerful bamboo and thatched-roof bungalows, likely stopping along the way to watch monkeys, sloths, and rare birds at play in this...

This low-frills, family-run eco-inn in the French Pyrénées melds tasteful comfort and green-mindedness with storybook environs. The Orri is an old stone and wood farmhouse that was renovated into ten bright, warm-hued guestrooms with simple furnishings and plush bedding. Its library and other cozy sitting areas are as inviting as the huge fireside dining table around which guests...

The wrought-iron "kicking horse" sculpture adorning the stone fireplace here pays tribute to those who once explored this land without recourse to such lush digs. James Hector was on a 19th-century expedition, searching for a western route for Canada's first transcontinental railroad, when his horse hoofed him so hard that his compatriots dug him a grave. But he regained consciousness and...

This quaint resort on the secluded island of Saba, in the Dutch Caribbean, is the ultimate green getaway. It's made up of 12 cute, colorful cabins (with names like "Bird of Paradise" and "The Tree Frog") tucked into a dense, oceanside rainforest. The relaxation of guests swinging in hammocks on their cottage porches is only intruded upon by singing birds and chirping frogs. Private porch hot...

The soaring centerpiece of this unique lodge is its cathedral-like great hall, made of towering cedar walls and 48-foot-high lodgepole-pine beams. It's a modern take on the Cree Nation's shabatwon (traditionally a more modest place made of teepees covered in moss and deerskin). It expresses the MoCreebec people's vision for their eco-lodge—providing a healing, sustainable spot...

Inn Serendipity is a quaint, century-old homestead on a five-acre organic farm amid the undulating green of rural Wisconsin. Its comfy Writing Room, where guests can add to an ongoing journal, is one of just two guestrooms at the B&B (the other is the laidback, funky Music Room). Visitors will be drawn out from under their soft, organic cotton linens by the smell of zucchini-feta pancakes,...

Devil's Thumb is one of those places where the Wild West and the lap of luxury converge. A rustic-cum-gilt-edged bolt hole, so to speak. Its main lodge has single rooms and suites, all classy-comfortable with warm wood, soft leather, and elegant rugs. Here, you'll find bright lounges, countless alcoves, and oversized chairs near the six-sided stone fireplace, all of which invite easy...

Visitors to Binna Burra today follow in the footsteps of generations of "bushwalkers" in this part of southern Queensland. Since the early 1930s, Lamington National Park has lured nature lovers and scientists to its insanely diverse rainforests (there are five different varieties here). These intrepid explorers wove their way through ancient Antarctic beech and fragrant eucalyptus forests,...

This simple lodge in Alberta's Bighorn Wildland country is the kind of place visitors return to time and again. Even though they want to keep it a hidden gem, guests blab to their friends and word gets out. And why wouldn't it? Part of the lure lies in the gracious hospitality of hosts Madeleine and Alan Ernst (and Cora, their canine sidekick) and their killer cooking. For others, it's Aurum's...

The monkeys and sloths hanging out in this verdant tropical forest are onto something: warm, hilltop breezes and sweeping views of the cobalt Caribbean amidst 250 acres of virtually undisturbed rainforest in which to frolic. The only things better about being a guest in Samasati's treehouse-like bungalows are the (human) creature comforts—warm, wood- and window-lined rooms and inviting...
