Dog Park Features & Amenities
For the Dogs
- Separate Enclosures for All Sizes: A smaller enclosure for small dogs sits apart from a larger space for big dogs, so each can play at its own pace.
- Agility Equipment: The gear sits on synthetic turf pads across the grass. There’s a line of weave poles, three hoop jumps, low hurdles, a ramp and a slatted arch for dogs to climb over.
- Drinking Water and Poo Bags: There’s a water station on-site, with bins and Poo Bag dispensers.
For the Humans
- Seating & Shade: Benches sit along the fence, one under a tall gum. The young trees planted inside are still staked and give little shade, so bring water on hot days.
- Public Toilets: There are no public toilets inside the dog park, but there are facilities in the wider Deerubbin Park precinct.
- No Lighting: The park isn’t lit, so it’s a daytime spot.
Insider Tip: After a run in the park, clip the leash on and follow the walking path along the Cornwallis riverbank to make a longer outing of it.
The Final Verdict
Cornwallis Dog Park at Deerubbin Park gives Hawkesbury dogs separate fenced areas for different sizes and a full agility course to work through. Parking is free at the gate, but shade is limited while the young trees grow, so summer visits are best early or late in the day.
