Downtown (El Centro) is the actual backbone of Cancún. What it lacks in history, it makes up for being a true melting pot — an exciting mix of the old traditional Mexico and an ultra-modern urban sprawl. Avenida Tulum, the main street, passing through the heart of the city, is easy to reach by public transport. The street is lined with shops, cafés, bars, and restaurants. Be sure to stop by Parque de las Palapas, on the market square, where locals come to chat and watch the entertainment provided by various local groups. The lively atmosphere and the sound of Mexican music are infectious, and any worries will quickly be postponed to "mañana." Browse around the artisan stalls and try some of the local sweet delicacies or visit the "Hippie Market" around the corner. In the evenings, the place to be is Avenida Yaxchillan with its lively restaurants and bars, popular with locals and tourists alike.

The Sky View Observatory has been the tallest building in Seattle and Washington state since 1985. At 932 feet tall, it is twice the height of the Seattle space needle tower, which you can even spot it from a distance. You can be certain this skyscraper is going to offer you sweeping city and mountain views, plus a cafe with bistro food, beer and wine.

Cenotes (sinkholes) are deep wells with crystal clear water that can be accessed when the roof of a cave collapses. Fed by underground rivers, the cenotes were the main source of freshwater for the Mayans and therefore are considered sacred. They are unique to the Yucatán peninsula, and still to this day, the underground cave system connecting all the cenotes remains largely unexplored. Witnessing the breathtaking beauty of the large clusters of stalactites and stalagmites being mirrored in the crystal clear cool waters is a unique experience. Every cenote has its own particular beauty, and putting on a swimsuit and snorkeling in the pool is an absolutely unforgettable experience. Some tour operators also offer cave diving excursions for very experienced divers.
