Law Walk is Kings Park's premier urban bushland trail. It is a 2.5 km loop walk that provides visitors with scenic views of the Swan River and a unique insight into biodiversity along the Mount Eliza escarpment.

Law Walk Named after Robert Oswald Law, Law Walk begins at Rotunda Two and continues along the ridge of the limestone escarpment to Dryandra Lookout. A loop walk is available here, and returns visitors to Rotunda Two via the Lotterywest Federation Walkway.

Throughout the walk, visitors may observe flocks of birds panning out in flying formation over the Swan River, yachts moored at Matilda Bay, dolphins frolicking, Carnaby's cockatoo feeding on Marri trees or New Holland honeyeaters darting through the Dryandra sessilis parrot bush.

Law Walk takes approximately 45 minutes to complete. This walk is suitable for people with moderate fitness as it includes steep sections. Wheelchair and pram access is available on parts of Law Walk, from Swan Carpark (off Forrest Drive). A wheelchair turnaround bay is provided as the trail steepens just before Dryandra Lookout.
