The valley floor of the aviary is a streambed full of trees and shrubs, and adorned with shallow pools and small waterfalls. Water goes down the valley and flows into a large pool, which is contiguous with a small lake outside the exit of the aviary and offers a nice place for watching waterfowl.

Display panels with graphic and textual illustrations are erected at the entrance of the aviary to explain the structure and ecology of a tropical rain forest, with particular reference to the bird communities in the aviary. ]]>
A tree-lined promenade leads into a fountain promenade incorporating a fountain pavilion where one can sit surrounded by water.]]>
Plants of different genuses and families are displayed at the Display Plant House on a rotational basis. Throughout the year, over 30 groups of these plants are shown including Orchids, Begonias, Anthuriums, Amorphophallus, Bromeliads, Herbs, Aquatic and Bulbous Plant, etc. Visitors can appreciate the beauty of various types of plants at the Display Plant House in different seasons during the year.]]>
The Humid Plant House is maintained at a year-round temperature ranging from 23℃ to 33℃ through an automatic heating and cooling system.

The automatic fogging system will produce a layer of floating water vapour underneath the glazed cover. The water vapour absorbs much of the solar energy during evaporation and is discharged through the vents on the rooftop. ]]>
To make the environment of the Dry Plant House more interesting, artificial rockery and mini canyons are constructed to simulate the habitat for plants of arid areas.]]>
