Concierge.com's insider take:
In botanical terms, this 400-acre nature preserve is fabulously rich: Scientists estimate that there is a greater diversity of plant life here than in all of North America. Centered around the high hill of Bukit Timah in the center of the island, the rain forest also retains nearly half the island's original native bird species and many small mammals. Anyone interested in exploring the rain forest is welcome; there's a visitors' center, and tours by well-informed guides are offered daily. Beware of the monkeys at Bukit Timah: They're cute and frolicsome, yes, but they'll swipe cameras and eyeglasses in an eye-blink.
