premise: Tourism in Mexico They appear out of nowhere like a heat-addled mirage on the flat, straight, mangrove-fringed road. The first sign of humanity in 40 miles, the tourists have ripened to pink under the glare of the tropical sun, with their legs wrapped around shiny red all-terrain vehicles buzzing down the asphalt like one giant invasive insect. It's a strange sight, all right. But it's eclipsed moments later by an even stranger one. Looming on the Caribbean just beyond the end of the road is the world's largest cruise ship, the Independence of the Seas, harboring a bounty of 3,811 passengers. Thanks to cruise ships like this one, Mexico's Costa Maya (not to be confused with the Riviera Maya farther north), set along a once mostly deserted stretch of the Yucatan Peninsula, is becoming one of the most visited, albeit least known, tourist regions in the nation. In 2006, just five years after the opening of the cruise ship facility here, 850,000 passengers sailed into port. By then, the once tiny fishing village of Mahahual had exploded from 80 souls dependent on the sea, to 3,500 dependent on tourism. The region begins about 80 miles south of Cancun and stretches from the vast Sian Ka'an Biosphere Reserve almost to the Belize border. It encompasses huge swaths of protected jungle, a number of lesser-known Maya archaeological sites, indigenous villages, pristine lagoons and top-notch diving. Plans call for low-rise, low-density development emphasizing small, eco-friendly hotels that cater to adventure seekers and cultural travelers. South of Tulum, a lengthy stretch of almost uninterrupted resort development comes to an abrupt halt at the northern edge of the Sian Ka'an Reserve. The UNESCO World Heritage site (whose name is Maya for "where the sky is born") is a 1.3-million-acre haven of tropical forest and wetlands. It's alive with more than 300 bird species, pig-like peccaries, monkeys, puma and jaguar. It harbors turquoise lagoons where orchids and bromeliads cling to mangroves whose spiny roots grasp the earth like gnarled fingers. Save for a few fishing lodges, Sian Ka'an isn't set up for overnight visitors. But day trips are organized by a number of tour operators, including Community Tours of Sian Ka'an, a cooperative formed in an attempt to keep profits - and residents - in the small Maya town of Muyil.
hypothesis: Costa Maya is still not well-known by tourists.
