Hornsby Park: Everything You Need to Know About the New Quarry Park

If you've driven past the old Hornsby Quarry and wondered what on earth was happening behind those fences, here's your answer — and it's worth the wait. The first stage of Hornsby Park is now open, and families are already clocking it as a go-to for fresh air, big views and easy weekend outings.

Hornsby Park: Everything You Need to Know About the New Quarry Park

If you've been watching that enormous Hornsby quarry site quietly evolve behind the scenes, this is your moment. The gates have officially opened at the first stage of Hornsby Park, and it's already delivering big energy for families.

The newly opened Crusher Plant Precinct sits on land that once powered Sydney's construction industry. Now, instead of machinery and dust, you'll find open lawns, walking paths and places to pause.

There's still a strong sense of the site's past — you can feel the scale of it — but it's been reshaped into a place where families can actually spend time, not just pass by.

So, where are the best spots in Hornsby Park to visit for families?

The Crusher Plant Precinct

The Crusher Plant Precinct is the first section of Hornsby Park to open — and right now, it's the main way families experience the entire site.

This was once the heart of a working quarry, where volcanic rock was crushed and sent across Sydney. Now, it's been carefully reshaped into a public space where you can walk, explore and actually take in the scale of it all.

The View Everyone Will Talk About

Make a beeline for the Southern Lookout. It's accessible, easy to reach, and the view is huge. You're looking out across the former quarry and surrounding bushland, and it really gives kids a sense of just how big this place is.

It's also a great reset point where you can stop, take it in, and then decide what to explore next. 

Sadly, there's no swimming at Hornsby Park. That big, tempting body of water you'll see from the lookouts? It's strictly look-but-don't-touch at this stage. Right now, swimming in the quarry lake isn't allowed, and it's not even confirmed if it will be in the future. The council has said the idea is still being assessed and would need to meet safety, access and funding requirements before anything changes.

Outdoor Areas Galore

This is an easy park to settle into. There are loads of grassy areas for kicking a ball around, picnic shelters for shade, and BBQ facilities if you're planning to stay a while.

It suits everything from a quick morning outing to a full afternoon hang, especially if you've got a mix of ages in tow. Plus, the new park is dog-friendly! Just make sure you've got your pups leashed at all times. 

The Heritage Steps & Walking Tracks

For families who like to keep moving, the Heritage Steps add a bit of adventure. They connect the precinct to the area near Hornsby Aquatic and Leisure Centre and wind through bushland on the way down.

They're steep enough to feel like an effort, but manageable for active families — and a good way to tire out the kids.

You can also link up with the Blue Gum Walk and the Great North Walk if you're keen to extend your visit beyond the park itself.

The MTB Trail at Old Man's Valley

Yes, it's still open! If your kids are the type who spot a bike track from a kilometre away and immediately want to ride, Old Man's Valley is going to be a major drawcard.

Tucked right beside Hornsby Park, this is one of Sydney's most well-known mountain bike trail networks, and it's been drawing riders for years — long before the new park opened. Most of the trail is still open, except for Jump Track, which remains closed due to construction.

More Reasons to Come Back

What's open now is just the first stage, and there's plenty still to come. Plans include a loop track for walking and cycling, more lookout points, a bike jump and pump track, and a large play space in Old Man's Valley.

It's safe to say, Hornsby Park is only going to get better over time! If your family is ready for somewhere new to stretch their legs, this one's an easy yes. Plenty of space, interesting terrain, and just enough adventure to keep everyone engaged.

Location, Parking & Opening Hours

Hornsby Park is located off Quarry Road, Hornsby, with the Crusher Plant Precinct now open.

There's free parking on-site, with gates open daily from 7 am to 5.30 pm (extended to 7.30 pm during daylight saving).

If you're arriving by train, it's about a 10-minute walk from Hornsby Station.

You can also access the park via the Heritage Steps near Hornsby Aquatic and Leisure Centre — just keep in mind the return walk is a bit of a climb.
