Although the Middle East has become the epicenter of over-the-top development, the 26-room Feynan Ecolodge takes a radically different approach. The adobe-colored property, 2 1/2 hours from Amman, is both austere and alluring—and true to its bedouin roots. Solar panels generate power, and house-made candles light the rooms at night. In the winter, olive-pit charcoal is burned in fireplaces for heat. Guests hike through the wildlife reserve, dine on traditional dishes, and get a taste of the authentic Middle East.
