Bidjigal Reserve - Platypus Track

Last updated April 2026

Kids delight in spotting the elusive platypus along the Platypus Track in Bidjigal Reserve, Castle Hill’s best nature walk for little explorers. The gentle 1.5km loop winds through shady eucalypt forests and along quiet creek lines where the water ripples early in the morning or late afternoon. Bring a pair of binoculars and a sense of adventure—this is the spot where Sydney’s smallest adventurers can feel like true wildlife detectives. It’s the kind of place that turns a simple walk into a mini expedition. Perfect for families craving a screen-free morning or a peaceful escape from the city buzz. **What to Bring** Lightweight shoes with good grip. Small backpack with water and snacks. Hat and sunscreen even on cloudy days. A notebook to sketch any wildlife spotted. A camera or phone for the inevitable platypus sighting photo. **Best Age Range** Best for 4–10 year olds. Toddler-friendly stroller sections exist but the whole track is best suited to confident walkers. **Good to Know** Pricing is free—entry to the reserve costs nothing. No bookings required—just arrive and start walking. Parking is available at the Castle Hill end of the track. Go early on weekdays to beat the heat and crowds. **Nearby** The playground at Castle Hill Showground, Sydney is five minutes away and has shade and picnic spots. **Tips From Other Parents** Go early in the morning if you want the best chance of spotting a platypus—it’s all about timing and quiet voices. Bring a spare change of socks—kids love splashing in the shallow creek. Pack a picnic to enjoy at the picnic tables near the trailhead after the walk.
