Learn about sinkholes, butterflies and wombats on the specially created walks and viewing platforms in Penambol Conservation Park.


Penambol Conservation Park conserves an important area of remnant vegetation and contains several interesting geological features, including the Caroline Sinkhole. Excavations in the sinkholes have revealed evidence of the original inhabitants, Boandik Peoples, who were likely to have used the area for shelter.

There are also several educational walking trails that provide an insight into the animals that live in the park. Follow the Wombat Walk which passes burrows that are home to the common wombat. The Butterfly Walk provides the opportunity to see and learn about some of the local butterflies such as the splendid ochre butterfly and orange species butterfly.

An evening walk offers the best chance of sighting wombats.

Opening hours

Open 24 hours a day, seven days a week.

This park is closed on days of Catastrophic Fire Danger and may be closed on days of Extreme Fire Danger.

Listen to the local area radio station for the latest updates and information on fire safety.

Traditional owners

Aboriginal South Australians are the first peoples of our State and have occupied, enjoyed and managed these lands and waters since the creation. For SA's First Peoples, creation ancestors laid down the laws of the Country and bestowed a range of customary rights and obligations to the many Aboriginal Nations across our state. 

Aboriginal peoples' oral histories and creation stories traverse the length and breadth of Australia’s lands and waters, including South Australian Parks. These stories interconnect land and waters with complex meaning and values and hold great cultural significance. We recognise and respect Aboriginal people's ownership of their stories and that they hold rights and obligations to care for Country. It is through these rights and cultural obligations and a shared goal to protect the environment for generations to come that DEWNR is committed to meaningful collaboration and involvement with Aboriginal peoples in the management of our shared parks.


The park is located on an inland dune and contains several significant features including Caroline Sinkhole, situated in the north-eastern corner. View the sinkhole from a suspended platform near the main car park on Carba Road.

The large sinkhole has collapsed into the underlying marine limestone. Look closely and you will notice the varying layers of the limestone in the walls.

Where sinkholes reach the watertable and have vertical sides, like Caroline Sinkhole, they are often called cenotes.

The watertable is presently low and only exists as small pools around the edge. Changes in vegetation types, clearly visible from the elevated viewing platform, indicate former water levels.

There are also several dolines scattered throughout the park. Dolines are formed the same way as sinkholes, but do not reach the watertable and often have gentle sides. The largest doline is located near the southern boundary.

The area was occasionally used as a military training camp during World War Two.
