Talking the rapid transit trains in Singapore is not only better for the environment, but it also allows you to experience Singapore a little bit more like a local. Grab an EZ-Link card or buy a Singapore Tourist Pass and use the MRT, buses, and your feet to explore the city. With the help of public transportation you can see more of Singapore in one day than most visitors can fit into a week. Start your tour at HarbourFront. Have breakfast, spend some time strolling along the water and enjoying the morning sun before you embark on your journey on the Yellow Line. Stop at Labrador Park, Kent Ridge Park, or Haw Par Villa. Switch to the Green Line and make a stop at Chinese Garden with picturesque pagodas, statues, bridges and plants. You can spend the afternoon here, wandering between the linked islands on Jurong Lake. Still on the Green Line, Tiong Bahru is great for lunch. For more parks, head to Pasir Ris, where you can cycle, ride horses and kids can have fun at a playground. In the evening, switch to the Purple Line to get to Chinatown. Colourful architecture, heritage temples and traditional eateries that serve dim sum and yum cha wait for you here. You can finish your day of exploration by taking the Blue Line to Bayfront, next to the Marina Bay Sands SkyPark. Have a drink with a panoramic view of the bay at sunset and enjoy the laser light show.

The most well-known branch of the Soumaya Museum on Plaza Carso houses the eclectic $700 million private art collection of one of the world’s wealthiest men. The glistening facade of the building with its swooping lines is a must for your Instagram feed. Inside, a spiralling ramp will lead you though several floors filled with works of European and Mexican masters. The museum's collection spans 30 centuries of art including sculptures from Pre-Hispanic Mesoamerica, Mexican art, works by European old masters and masters of modern western art such as Auguste Rodin, Salvador Dalí, Bartolomé Esteban Murillo and Tintoretto. It is called one of the most complete collections of its kind.

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.

Make a side trip to the Moeraki Boulders; these huge spherical boulders are littered over a sandy beach under an hour away from Dunedin. Stop at the famed Fleurs restaurant, in the fishing village on the bay at Moeraki, and dine with fresh and smoked seafood on the upper floor and enjoy the view.
