This ancient fortress sits on top of a hill right next to the National Botanical Garden and enjoys an unrivalled view over the city. For this reason it had been a key strategic point in the city's defence for many centuries, until it was almost destroyed in an earthquake in 1827. Visitors can reach the fortress on foot or with the new cable car from Rike Park.

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.
