Do you dare to swim with these ocean giants? From around May to September, sharks appear close enough to the coast of Cancún, and several tour operators let you observe them and even swim and snorkel with them (all safety precautions, naturally, in place).

São Paulo's very own Central Park boasts over 2 million square meters of green space. The best way to explore it is to hire a bike. On Sunday mornings, there are free music concerts in the Praça da Paz. Here, you’ll also find a few interesting museums, such as the Museum of Modern Art, the exhibition hall OCA, and the Afro Brasil Museum.

The Metropolitan Cathedral of São Paulo or simply Catedral da Sé is an imposing neo-gothic church located in Praça da Sé. It is 46 meters wide, 111 meters long, and has a dome 65 meters high. It was one of the first churches built in São Paulo–its first construction started in 1591–and today it is considered one of the largest neo-gothic temples in the world. It contains a crypt with the remains of Cacique Tibiriçá, the first Indian converted and baptized by the Jesuits José de Anchieta and Leonardo Nunes. It is also worth noting its grandiose organ–the largest in Latin America.
