A 3-hectare National Orchid Garden that opened in 1995 and showcases 700 species and more than 2,000 hybrid orchids; a Cool House that simulates a tropical mountain forest; a 250-species strong Palm collection (Palm Valley); an Eco Garden at the Bukit Timah location (plants with medicinal, culinary and industrial uses); and a 6-hectare natural remnant rainforest.

Walking the Bukit Timah trails, you follow in the footsteps of famous biologists such as Alfred Russel Wallace, who along with Charles Darwin is the co-founder of evolutionary theory. Species new to science, such as the fresh water crab Johora Singaporensis which was identified in 1986, are still found here.

Previously known as the Central Park, this 19-ha "hill of history" was the residence of Sir Stamford Raffles, who established his government house on this hill in 1819.

Visitors to Fort Canning Park can find a number of relics reflecting the past glory of this place. Keramat Iskandar Shah, venerated by Muslims and believed to be the ancient tomb of the last Malay King, stood at the foot of the hill.

Forests in the more accessible southern area of this 2,000-ha reserve are mostly mature 90-year-old secondary forest with some primary forest patches. There is a wide diversity of animal species, including endangered creatures such as the Lesser Mousedeer, the Malayan Pangolin (scaly anteater) and the Flying Lemur. Forest birds such as babblers, barbets, cuckoos, flowerpeckers and sunbirds abound. The more open sunny areas offer great butterfly watching.

This 1,019 hectare island is the last outpost of a vanishing, laid-back way of life. Landscapes range from rocky beaches to mangrove swamps, through abandoned orchards and coconut, banana or rubber plantations, to prawn farms, and forest. The southeast coast of Tnajong Chek Jawa harbours a sandy mudflat habitat, rich in bio-diversity. At this corner, you may also find, perhaps the tallest, largest and oldest tre on Ubin island, a Pular tree, growing by a trail.

The 130-hectare Wetland Reserve is an internationally significant link in the regional chain of stopovers for birds on the great annual north-south migration from September through to March. It is particularly important for wading birds, which feed on the adjacent costal mudflats at low tide and fly into the Park's ponds when the sea covers the mudflats. The site was established at the end of 1993 as a conservation area, with a visitor center, boardwalks running through the mangroves, two observation towers, and bird-watching hides and screens looking out onto a variety of ponds - both brackish and freshwater. It exists in an agro-technology area, alongside vegetable farms, orchid nurseries and fish farms.
