Robertson's Roundabout is a rewarding 2.3 kilometre circuit in Royal National Park that packs a surprising amount of variety into a short distance. Most walkers complete it in a little over an hour, though you may find yourself slowing down to take in the changing scenery as the track climbs away from the river and rises onto the ridge.
Beginning at the Royal National Park Centre, the walk leads across the Hacking River and quickly starts to climb. The track gains height through open forest, and before long the river spreads out below you in soft bends. Higher on the ridge, the view stretches all the way to Cronulla on a clear day, a reminder of how close this pocket of bushland sits to the edge of the city. It feels surprisingly peaceful up here, with only the rustle of the canopy and the calls of birds carrying across the slope.
Once you reach the ridge, the circuit becomes a pleasant wander through dry heath and open woodland. The path can be faint in places, so the arrow markers are helpful for staying on course. From this higher ground, the country surrounding the Hacking River opens out around you, framed by sandstone and thick patches of scrub. It is a beautiful area to move through at an unhurried pace, especially when the light filters across the tops of the trees.
The descent starts gradually, then steepens as the trail winds down rocky steps and zigzags back towards the river. The sound of water and the cool air rising from the flats signal your return to Currawong Flats, where the forest becomes lush again. Crossing the bridge takes you back to Lady Carrington Drive, and from here it is a gentle stroll past the picnic areas before you arrive at the visitor centre once more. A short set of stairs leads you back onto the grassed clearing of Ironbark Flats, where the loop finishes.
This is a compact but enjoyable walk that gives you a little taste of everything the park offers. The mix of river views, ridge top scenery, changing vegetation and a few short, steep sections keeps it interesting without being overly demanding, making it a great option for anyone exploring the Audley area.

Located near Cronulla, just an hour’s drive from both Sydney and Wollongong, Royal National Park is a sprawling 16,000-hectare expanse of coastal cliffs, secluded beaches, lush rainforests, and tranquil rivers.

Known locally as "the Nasho" or simply "the Royal," this historic park offers an incredible variety of landscapes, making it a prime spot for walking, hiking, cycling, and countless other outdoor adventures.
From the towering sandstone cliffs along the Coast Track to the serene freshwater swimming holes of Karloo Pool, the park’s diverse terrain caters to all levels of walkers and hikers. Scenic bushwalks wind through dense eucalypt forests, past ancient Aboriginal rock engravings, and along windswept headlands where the ocean stretches endlessly to the horizon. Seasonal wildflowers bring bursts of colour to the landscape, while waterfalls cascade over rock ledges into pristine pools below.

Beyond its network of tracks, the park is a playground for nature lovers. Picnic areas are scattered throughout, perfect for a relaxed lunch after a morning on the trails. Surfers flock to Garie Beach for its consistent waves, while birdwatchers can spot lyrebirds, black cockatoos, and sea eagles soaring overhead. In the cooler months, the clifftops provide one of the best vantage points for watching humpback whales as they migrate along the coast. Those looking to extend their visit can set up camp at North Era or book a stay in one of the historic cottages dotted throughout the park.
