Sawn Rocks, NSW: A Geological Marvel In Mount Kaputar National Park
Swan Rocks is an ancient natural wonder, created by the Nandewar volcano millions of years ago. It has stood the test of time for literally millennia – it’s mindblowing if you think about it.
This 40-metre-tall cliff with organ pipe-shaped rocks is located in the northern section of Mount Kaputar National Park, New South Wales.
It’s free to enter and has all the amenities, so you can easily spend a full day there! There’s a walking track and a lookout, as well as a picnic area.
We’ll tell you all about it below, as well as everything you need to know to plan your visit – how to get there, the best time to visit, other things to do while you’re there, and more!

How were the Sawn Rocks formed?
We recognise the traditional owners of this land, the Gamilaroi.
This rock formation came to be about 13-21 million years ago, when the Nandewar was a volcano, not the mountain range we know today.
The basalt lava flow of this ancient volcano poured and cooled slowly, ultimately creating these sharp, hexagonal columns through a process called “columnar jointing”.
This slow process happened inside the volcano, so it took millions of years of erosion for this to look the way it does today. It’s also believed that these “organ pipes” continue several metres under the surface!
Over millennia, water, wind, and especially plant roots began to infiltrate the cliff face. Roots from trees and other vegetation sneak into tiny cracks, gradually prying the rock apart.
This has caused pieces of rock to break off and fall, gradually changing the landscape. For example, the fallen rock fragments contributed to the formation of the creek bed for the Bobbiwaa Creek below.
3 Things to do at Sawn Rocks, NSW
This place is small but there are a few cool things to do:
1) Sawn Rocks walking track
The walking track at Sawn Rocks is an easy 1.5km hike (15-20 minutes). The trail is well-maintained and mostly flat, along beautiful bushland before the rocks come into view.
As you walk, keep your eyes peeled for the local wildlife! You will spot birds, lizards, and even kangaroos if you’re lucky.
The flora is just as impressive, with plenty of native plants lining the track. It’s a real treat for nature lovers and a great way to stretch your legs.
When you reach the end of the track, you’ll be greeted by the spectacular sight of Sawn Rocks. The pentagonal basal pipes are mind-blowing!
2) The Lookout
The lookout is at the end of the walking track, positioned in such a way that it gives you a full-frontal look at the rock formations.
This spot is prime for photos, but know that it can get crowded during the weekends or holidays. Be patient, it’s worth waiting a bit for the perfect photo opportunity!
3) Sawn Rocks picnic area
The picnic area at Sawn Rocks is next to the car park, making it super convenient.
It’s a top spot to relax and refuel after your walk. The tables and BBQ facilities are well-maintained, so you can easily set up a meal with the family. There are toilets as well.
Shade is plentiful, thanks to the surrounding trees. You can spread out a blanket and kick back without worrying about the sun.
How to get to Sawn Rocks?
Sawn Rocks is along Killarney Gap Road (Narrabri, NSW).
To get there, the easiest way is to head to Narrabri. It’s a 6-hour drive from Sydney and a 6.5-hour drive from Brisbane.
Once you’re there, it’s about a 30-minute drive north via the Newell Highway. Follow the signs to Mount Kaputar National Park, then turn onto Killarney Gap Road. Keep an eye out for the Sawn Rocks Road turnoff!
Once you’re on Sawn Rocks Road, it’s an easy drive. The road is sealed and in good condition, so any vehicle will do. Follow this road to the end, where you’ll find the car park.
If you’re visiting during weekends or holidays, try to get early – it can get crowded and can be impossible to find a spot.
Public transport options are limited, so driving is your best bet. If you don’t have a car, consider hiring one in Narrabri.
This will give you the freedom to explore at your own pace and check out other spots in the national park. We recommend using Rental Cars for that, as they find excellent deals in Narrabri and other nearby towns. Check it out here!
