Shaped like a diamond, Singapore is only 7,349 sq ft (683 sq m) in size with 120 miles (193 km) of shoreline. The urban center sits at the southernmost tip of the island. At the city’s outskirts, pre-war neighborhoods consist of low-rise streets with homes and stores where traditional trades are still practiced. Beyond these, New Towns – clusters of high-rise apartment buildings – are supported by schools, businesses, and other facilities. The Mass Rapid Transit line (MRT) runs a full circle around the major New Towns, linking them with the city. It is possible to spend several days exploring the vast countryside.
