Located right outside Sentosa's cable car station. If you are from any other places in Sentosa, take either the Blue Line bus (from Siloso Beach, Visitor Arrival Centre, Ferry Terminal) or the Yellow Line bus (from Siloso Beach, Ferry Terminal).
Located on Mount Imbiah, this place is actually a collection of various attractions for Sentosa visitors. The lookout also offers a spectacular view of the city skyline.
Right outside the cable car exit is the Carlsberg Sky Tower (SGD10.00/SGD5.00 for Adult/Child, 0900-2100 hrs daily, last admission at 2045 hrs) which is Singapore's tallest observatory tower at 131 metres. Then there is the newly-opened Images of Singapore (SGD10.00/SGD7.00, 0900-1900 hrs daily, last admission at 1830 hrs) which offers interesting displays of Singapore's past and present. Nearby is also Sentosa's latest attraction called Sentosa 4D Magic (SGD16.00/SGD9.50, 1000-2100 hrs daily, last show at 2030 hrs) that promises you a "mind-blowing" interactive experience in its 4D-theatre.
A little further down the road are the Butterfly Park & Insect Kingdom (SGD10.00/SGD6.00, 0900-1830 hrs daily, 1,500+ butterflies), The Merlion Walk (SGD8.00/SGD5.00, 1000-2000 hrs daily, last admission 1930 hrs) and the thrilling Sentosa Luge, a mixture of engine-less go-cart and toboggan that goes downhill for a few hundred metres (SGD8/1 ride, SGD15/2 rides, SGD20/4 rides, SGD3/SGD5 for chairlift one-way/round-trip, 1000-1800 hrs Mon-Thu and 1000-1900 Fri-Sun).
Fantastic view. But wary of the various fees on its many attractions because they can cost you dearly.
