Coba, Mexico
When it comes to ruins on the Yucatan Peninsula, Tulum gets all the buzz -- and the bulk of visitors. But head farther inland to Coba, and you can not only enjoy the ruins with fewer crowds, but you can climb them too. The site's largest temple, Nohoch Muul, has a steep stone stairway to the top, strung with a guide rope to help you balance. After you summit, reward your efforts with a dip in the crisp turquoise waters of the Cenote Cho Ha sinkhole, a short drive away.
Stay: Each of the 41 palapa-style villas at Playa del Carmen's sexy The Tides Riviera Maya features a hammock-strung terrace, an outdoor shower and a private plunge pool.
