Entrance gate for Sentosa island in Singapore

Sentosa is a tourist pleasure, meant to be an island of fun and leisure. Just off the Central region of Singapore, it is designed to be a place full of thrills, rides, water parks, aquariums, and other such stuff. For visitors from outside Singapore, and even for Singapore residents, it is a fun place. Sentosa is accessible through road (taxis or buses), walking (on a short boardwalk), a small train, or a cable car (am not sure whether you can arrive there by helicopter though; but if you are important enough, then maybe you can also get there by helicopter). Many of these transport methods are also attractions by itself, with the cable car and the elevated train called Sentosa Express being the prime attractions. Entry to Sentosa is not free, with a charge being levied no matter whatever method you employ to get there, but once there, internal transportation is all free.

Sentosa has a number of tourist attractions that draw visitors around the year, although times such as the Chinese New Year and Christmas being more important; and as you would expect, weekends are much more busy than weekdays, so if you can schedule your trip, try to make it on weekdays rather than on weekends. One of the prime attractions inside Sentosa is the Universal Studios Park, which is a full day activity with plenty of rides, shows, and other such stuff. You may not find gigantic roller coasters such as in some amusement parks such as in the US, but the roller coasters here are also fun. Besides Universal Studios, you have a water park, you have a sky tower that provides a high view of the city, there is a replica of the Merlion that allows you to climb inside, there is an excellent laser show in the evening, 4d rides, an aquarium, and so on.
