Singapore's strategic location at the southern tip of the Malaysian peninsula has ensured its importance, which is greater than its size might seem to justify. Singapore consists of the island of Singapore and some 63 islets within its territorial waters. The main island is about 26 mi/42 km from west to east and 14 mi/23 km from north to south. It's a mostly undulating country with low hills (the highest, 540-ft/166-m Bukit Timah Hill, is to the northwest of the city).
Singapore's Central Business District actually spreads across both the central and southern parts of the island (you'll know when you're there - it boasts striking high-rise structures). You can get a good visual orientation to the city as you cross the Benjamin Sheares Bridge on the East Coast Parkway, which links the airport to the city center. The Singapore cityscape looks magnificent, particularly at night when buildings are brilliantly lit. Offshore, there appears to be another city all lit up because of the many ships anchored there - Singapore is one of the busiest seaports in the world.
Many of the city's attractions are clustered closely together. Orchard Road, the shoppers' haven, is located in the northern part of the city center. Chinatown, where you'll find Boat Quay, is just to the southeast of Orchard Road, while Little India is northeast. Sentosa Island, with its many amusements, is directly to the southwest of the city center. These frequently visited neighborhoods, as well as more suburban areas, remain a bustling hive of pedestrian activity well into the evening.
Foreigners holding travel documents issued by some countries will require either a Business or Social Visit visa to enter Singapore. For more information on VISA application, please visit http://www.ica.gov.sg/services_centre_overview.aspx?pageid=252&secid=165.
