Kapawi Ecolodge and Reserve

Room 19, Kapawi Ecolodge & Reserve, Kapawi, Ecuador; 593-4-228-5711; kapawi.com. There are 19 rooms; doubles range from $670 per person for three nights to $1,405 per person for seven nights.

Brush aside the mosquito netting, roll out of bed, and step onto the terrace, and you'll receive a boisterous greeting from a brown jacamar, an egret, or another of the 500-odd bird species residing in this pocket of the biodiverse Amazon jungle near the Peruvian border. Perched on stilts above the Capahuari River, Ecuador's remote Kapawi Ecolodge—two planes and a boat ride from Quito—isn't just environmentally conscious, it's downright reverent. Solar panels power the lodge, and the 19 thatched-roof cabanas are built of palm and mahogany without a single nail, following the methods of the indigenous Achuar. After getting your fill of the view, slip on the rubber boots left at your door and head down to the river for a canoe ride. As you float, peer into the sweeping branches of the hundred-foot trees: You might even spot the rarely seen three-toed sloth.
