Organ Pipes Trail is a 3km, grade 2 circuit hike, located in Organ Pipes National Park, Victoria. The hike should take approximately 1.5hrs to complete.

Hike Summary

The Organ Pipes Trail commences at the Visitor Information Centre and follows the walking track to explore the many wonderful features of the park. The Organ Pipes, a set of basalt columns formed by the cooling and cracking of molten lava, are the parks best known feature. Visitors can enjoy the fantastic range of picnicking, walking, bird watching and photography opportunities available.

1. Keilor Plains
Walk through the small gate to the two viewing platforms. All around you are the basalt Keilor Plains, one of the world's largest lava flows. These plains, formed by lava which came from volcanoes near Sunbury, are fairly flat except where streams, like Jacksons Creek below you, have cut deep valleys.

2. Native plants revival
As you walk down to the Organ Pipes look closely at the trees and shrubs. In 1972 this area was covered with weeds, mainly thistles and boxthorn. Each year since the weeds have been removed more native trees and shrubs have established. The task of re-establishing native grasses and herbs has been more difficult, but there is now a substantial field of Kangaroo Grass (themeda triandra) on the north side of the track.

3. The Organ Pipes
About a million years ago, molten lava flowed over the Keilor Plains from Mount Holden and other nearby volcanic hills. It filled the depressions and valleys of the former land surface, then cooled and solidified into basalt. Here at the Organ Pipes, it is believed that the lava filled a river valley running at right angles to Jacksons Creek and was perhaps 70 metres thick. Once a surface crust had formed, the lava beneath cooled very slowly. During cooling, the lava contracted and surface cracks developed (as they do in a drying mud puddle). As it continued to harden, the cracks lengthened until the basalt mass was divided into columns.

Over the million years since the lava flow, Jacksons Creek has cut a deep valley through the basalt and revealed the Organ Pipes.

4. Sandstone Bedrock
Walk down the stream for 200 metres, past wellestablished trees and you will see yellowish rocks across the creek. These are sandstones and mudstones, sedimentary rocks laid down under the sea. Fossils in these old rocks suggest they were formed about four hundred million years ago. The old river valley now filled by the Organ Pipes was cut in this sedimentary bedrock.

5. Rosette Rock
Now walk back upstream. About 400 metres past the Organ Pipes, look across the creek to see Rosette Rock, a radial array of basalt columns like the spokes of a wheel.

6. Tessellated Pavement
Three hundred metres further on is the Tessellated Pavement, which consists of the tops of basalt columns 'filed down' by Jacksons Creek.

7. Scoria Cone
You can now return to the car park by the shortcut path shown on the map. The carpark is on an eroded scoria cone - a small volcano that ejected molten volcanic rock called scoria. Scoria is reddish-brown and light in weight; it has many airholes because it was full of steam when ejected.

About the region

The Organ Pipes National Park is located at the eastern-most edge of one of the world’s largest ancient volcanic lava flows, stretching 350 kilometres from the edge of Melbourne to the western border of Victoria.Towering above charming Jacksons Creek, the impressive basalt columns that resemble organ pipes were formed about a million years ago when huge quantities of molten lava were ejected from volcanoes near what is now Sunbury and flowed over the Keilor Plains. These plains are fairly flat except where streams such as Jacksons Creek have cut deep valleys over the years.

Getting there

Organ Pipes National Park is just off the Calder Freeway about 20km north-west of Melbourne.


Access to the Organ Pipes, Rosette Rock and the Tessellated Pavement is via a sealed but very steep path. Just below the picnic area the slope reaches a gradient of 1 in 4. This walk should only be undertaken by fit, surefooted visitors.

  1. Did this hike with my daughter a couple of weeks ago and the shortcut path back to the carpark is very slippery, muddy and steep

    1. My husband and I did the walk today and found the Rosette Rock is currently fenced off due to repair work. It is still possible to see it tho.

    1. I just saw this and didn’t realise it popped up because you tagged us and I was going to tag you both haha looks great!
