[2] Forming a large green lung in the geographical centre of the city, it houses several recreational sites, including the Singapore Zoo, the Night Safari and the River Safari, as well as several newer facilities built to encourage public appreciation of the reserve, such as the HSBC TreeTop Walk.

[7][8] Most forests in the CCNR were cleared for logging and cultivation unlike Bukit Timah Nature Reserve, which remain relatively undisturbed.

Walkways and boardwalks in the reserve, which range from 3 to 11 kilometres long, allow visitors to enjoy a closer feel to nature.

Central Catchment Nature Reserve is the only place in Singapore where Raffles' banded langur monkey remains, with a population that has been severely diminished.

Visitors will only be able to travel along the narrow walkway in one direction, by entering from the Bukit Pierce entrance and exiting through the Petaling Trail.

This is part of National Parks Board's efforts to educate people about the conservation of nature areas in Singapore.

Due to rapid urbanisation and habitat loss, the population at Bukit Timah Nature Reserve had died out in 1987.
