Bathtub troughs have been carved into the rock faces and rustic huts timbered from local wood. There is no electricity, no telephone, no television, nothing to disturb the experience of nature. Guests fall asleep to the murmurs of the surging waves and wake up to the birds chirping. Nature is the main focus in this 15-room eco-resort on Mexico’s Riviera Maya. The mysterious cult sites of Maya are only a stone’s throw away. The shimmering turquoise Caribbean Sea makes snorkeling tempting.
