The park's stone castle was constructed by workers under the Unemployment Relief Scheme during the Great Depression.
It contains a rare remnant of Sydney Turpentine-Ironbark Forest, an endangered ecological community.
The park was originally a private estate owned by James Oatley, a convict watchmaker who arrived in Australia in 1815.
The shoreline features a series of sandstone rock platforms that are accessible during low tide.
The park's layout was designed to retain significant areas of natural bushland rather than formal gardens.
The local council occasionally conducts controlled burns to manage undergrowth and encourage native regeneration.
Oatley Park is a 45-hectare bushland reserve located on a peninsula extending into the Georges River. The park preserves significant remnants of the original vegetation of the St George district, including diverse eucalypt forests and mangrove communities. A primary feature is the Oatley Park Castle, a stone structure built in the 1930s as a Depression-era public works project. Visitors can access a network of bushwalking tracks that lead to various vantage points overlooking the river. The reserve provides critical habitat for local bird species, making it a popular site for bird watching. Recreational facilities include public barbecue areas and playgrounds positioned near the riverfront. The park's terrain varies from elevated ridges to coastal foreshore environments. It is managed by the Georges River Council and serves as a major regional natural landmark.

Wear sturdy, closed-toe walking shoes to navigate the uneven terrain on the bush tracks.
Bring insect repellent during warmer months, especially when hiking near the mangrove or river areas.
Check the Georges River Council website for any fire bans or park alerts before planning a bushwalk.
Do not attempt to swim in the Georges River at the park's edge, as it is not a designated patrolled swimming beach.
Keep dogs on a leash in designated areas and strictly follow 'leave no trace' principles to protect the bushland.
