Singapore is at its most Singaporest at Marina Bay, where the Singapore River terminates prior to reaching the Pacific Ocean. This is Singapore's "Window to the World" where the city state shows how much progress has been made and how wonderful the city is compared to the rest of the world.
THE MERLION
If you are only in Singapore for an evening or shorter and simply looking for the place to go, with all the action, and somewhere to grab a meal and a beer, its Marina Bay and the Quays. South of the Raffles Place MTR Station runs a promenade along Marina Bay. Across the bay is Singapore's most iconic building, the Marina Bay Sands. Continuing along the promenade to the Singapore River leads to the Merlion, Singapore's top selfie photo destination.
MARINA BAY SANDS
Marina Bay Sands may be the most iconic hotel opened in the past twenty years. The hotel features a surfboardesq platform spanning three towers.
On the roof is an infinity pool - another major selfie stop.
GARDENS BY THE BAY
Singapore's modern garden complex on the back side of the Marina Bay Sands hotel. The gardens are accessible from the hotel and the Bayfront MTR station. Access is free, however, admission is charged for a few of the attraction areas. The Skywalk is only $5 SGD. Tickets to the Cloud Forest and the Flower Dome was $28 SGD, a bit to pricy for someone not into flowers.
