The Organ Pipes are one of the worlds largest exposures of volcanic rhyolite columns. The exposed rock columns protrude from the rocky landscape of volcanic hills over 1500 million years old.

The Organ Pipes are one of the top attractions in Gawler Ranges National Park. They are formed from Rhyolite, a silica rich (felsic) extruded volcanic rock that has cooled into the massive, 4,5 or 6 sided columns. One of the best places to see the Organ Pipes within the park is Kolay Mirica Falls.

The Rhyolite within Gawler Ranges is Eucarro Rhyolite. These viscous flows normally only produce about 1 km³ of lava, yet the Gawler Range flow, produced in the Mesoproterozoic era (1600 to 1000 million years ago) is a truly vast 675 km³ or more and up to 300m thick in places. This has produced the largest Rhyolite column formations on earth.

Road: Gawler Ranges National Park is about 160km east of Port Lincoln, 460km from Adelaide. It is about 120km from Streaky Bay.
