Start out in East Coast Park, a 20km stretch of beach and green space running along the straights of Singapore. Get there early to watch groups of aunties and uncles doing Tai Chi, then fuel up for an active morning yourself with some traditional kaya (a sweet coconut and egg jam) butter toast at Old Town White Coffee located at the Playground @ Big Splash. Pick up a bike or rent inline skates at the same complex and cruise along the smoothly paved paths while gazing at the massive tankers out at sea.
Turn in your wheels when you've had enough and head to the most iconic wheel in Singapore: The Flyer, the largest observation wheel on earth. It might be a little touristy, but you're sure to be impressed by the sheer engineering of the thing.
Next, have your taxi driver drop you off in the Arab Quarter where you can lunch at any of the eateries along Bussorah Street. At the end of this road the Masjid Sultan mosque rises like a mirage. It is the largest mosque in Singapore and well worth a visit, as is the nearby Malay Heritage Centre.
From man-made marvels to natural ones, as the sun begins to set, it's time to head to the Singapore Zoo to check out the outstanding Night Safari, the first night-time zoo in the world. Have dinner on-site (they have an extensive buffet) and then wander the paths viewing night creatures, including snow leopards, hyenas and lions in natural, dimly lit settings. If you're brave enough, enter the bat area where you can get eye-to-beady-little-eye with huge fruit bats.
Finish off your last night in Singapore by getting an excellent perspective on the city at the New Asia Bar located on the top floor of the Swissôtel Stamford, Singapore's tallest hotel building. Take in the sweeping views through huge plate glass windows and let the great mix of tunes and friendly crowd on the dance floor see you off in style.
