Singapore is a major industry and contributor to the Singaporean economy, attracting 17.4 million international tourists in 2017, more than 3 times of Singapore's total population.[1] It is also environmentally friendly, and maintains natural and heritage conservation programs. Along with this, it also has one of the world's lowest crime rates. As English is the dominant one of its four official languages, it is generally easier for tourists to understand when speaking to the local population of the country, for example, when shopping. Transport in Singapore exhaustively covers most, if not all public venues in Singapore, which increases convenience for tourists. This includes the well-known Mass Rapid Transit (MRT) system. Singapore is the 5th most visited city in the world, and 2nd in Asia-Pacific.
The Travel and Tourism Competitiveness Report 2017 ranks Singapore 13th out of 136 countries overall, which was the third best in Asia only behind Japan (ranked 4th) and Hong Kong (ranked 11th). The report ranks Singapore's business environment, international openness, also travel and tourism policy and enabling conditions as the best in the world (ranked 1st). However, the island nation scored rather low in natural and cultural resources sub-index (ranked 40th).
The Orchard Road district, which is dominated by multi-storey shopping centres and hotels, can be considered the centre of tourism in Singapore. Other popular tourist attractions include the Singapore Zoo, River Safari and Night Safari, which allows people to explore Asian, African and American habitats at night without any visible barriers between guests and the wild animals. The Singapore Zoo has embraced the 'open zoo' concept whereby animals are kept in enclosures, separated from visitors by hidden dry or wet moats, instead of caging the animals, while the river Safari, features 10 different ecosystems around the world, including the River Nile, Yangtze River, Mississippi, Amazon as well as the Tundra and has 300 species of animals, including numerous endangered species.
Jurong Bird Park is another zoological garden centred on birds, which is dedicated towards exposing the public to as much species and varieties of birds from around the world as possible, including a flock of one thousand flamingos. The tourist island of Sentosa, which attracts 19 million visitors in 2011, is located in the south of Singapore, consists of about 20–30 landmarks, such as Fort Silos, which was built as a fortress to defend against the Japanese during World War II.
Guns from the World War II era can be seen at Fort Silos, from a mini-sized to a 16-pound (7 kg) gun. Moreover, the island has built the Tiger Sky Tower, which allows visitors to view the whole of Sentosa, as well as the Sentosa Luge, a small one- or two-person sled on which one sleighs supine and feet-first. Steering is done by shifting the weight or pulling straps attached to the sled's runners. Among the latest tourists’ attractions built in Singapore includes the two integrated resorts which houses casinos, namely Marina Bay Sands and Resorts World Sentosa, a Universal Studios theme park and Gardens by the Bay.
