West Coast Park was first developed in 1979 on a piece of reclaimed land off West Coast Highway, covering an area of 50 ha. In the late eighties, PSA commenced reclaimation on the coastline of the park for port development. The massive port development took up almost two-thirds of the park's coastline. Built on reclaimed land, the settlement of the land led to a waterlogged problem on the lawn area, further deterring park visitors.

To revitalize the park and to attract more park visitors, NParks has improved the infrastructure and added in many interesting features and facilities. The Phase 1 development, which covers area 2 and 3 (western portion), was commenced in November 1998 and has been completed in July 2000.

With the theme "Play Centre in the West", the western portion of West Coast Park has been transformed into a haven for park visitors who enjoys challenging and adventurous activities. Standing at the centre core of area 3 is the Adventure Play Area that caters to people of different age groups, from toddlers to young adults. This is the heart and most active zone of West Coast Park . If you like a quiet and peaceful environment, the eastern portion at area 1 would be a good choice for park users to rest and relax.
