Oatley Park is a suburban bushland haven situated on the Georges River, about 20km south of the Sydney CBD. An hour long circuit takes in wetlands, mangroves, and views of the saltwater Georges River and a couple of its side arms. There are plenty of shorter options however, and you can just wander through the park if you like; it’s not big enough to get seriously lost in.
There’s also a netted swimming area and BBQ facilities you can enjoy. (Best not to swim here after heavy rain due to runoff pollution). We drive there, but Oatley train station is only about 1.5 km away, and it’s quite a nice suburb to walk through. Track notes at the end.
Here’s a link to Oatley Park on Google Maps. There’s actually a network of tracks and roads offering some variety, but we tend to do a circuit anti-clockwise from the main entrance that keeps to the outside of the park and adjacent Lime Kiln Bay Reserve. To do this, start at the end of Oatley Park Ave, and walk down the hill on Dame Mary Gillmore Rd to the 90 degree corner, (where the road becomes Bay Rd), then drop down into Lime Kiln Bay Reserve. Take a right at the bottom and walk through the constructed wetlands, curving around left to stay within the reserve, through bushland, and eventually passing by Hurstville Golf Course. Continue on along a boardwalk through mangroves, and take a left when you emerge on the edge of a suburb, passing over a footbridge to a turning circle at the end of a road (now in Oatley Park). Walk up the road about 400m and keep an eye out for a track on the right (down a handful of steps). Take this track (maybe the nicest bit?) which runs around Lime Kiln Head to Jewfish Bay Baths. Keep roughly to the foreshore past the swimming area until the track heads away from the water to meet Douglas Haig St. I like to walk up the road about 200m to a small car park for views of the Georges River. There’s a network of tracks through the bush opposite which take you to another road within the park (keeping to the right will minimise time spent on the road). Take a right along the road to arrive back at the main entrance.
