The government-funded, large-scale gardens next to Marina Bay Sands opened with much well-deserved pomp in 2012. Highlights include a futuristic grove of "Supertrees"—giant vertical gardens—and two armadillo-shaped conservatories. The Flower Dome is home to plants from the Mediterranean and subtropical regions, while the Cloud Forest is veiled in mist and houses the world's largest indoor waterfall. The OCBC Skyway is a 420 foot (128 m) walkway that connects several of the Supertrees and offers a great view from above. While fees apply for both the Skyway and conservatories, visitors can wander around the Gardens until 2 am free of charge.
