If you've ever wondered what Singapore was like when its founder Sir Stamford Raffles first stepped ashore in 1819, the rustic, leafy island of Pulau Ubin will give you a pretty good idea. Politically, it's the same country but geographically, it's a whole other time and world. The island's highlight is Chek Jawa, a lovely marine sanctuary of rare sea creatures and wildlife. Because the area's ecosystem is so fragile, visitor numbers are strictly controlled on a first-come, first-served basis; contact the National Parks Board Ubin Information Kiosk (65-6542-4108) for visiting information. From the Tanah Merah MRT station, take a cab to Changi Point Ferry Terminal (Changi Village) and then hitch a 10-minute boat ride out; round-trip tickets cost S$5.
