Caroona Creek Conservation Park is a protected area located in the Australian state of South Australia in the localities of Collinsville and Mount Bryan East about 173 kilometres (107 mi) north-east of the state capital of Adelaide and about 19 kilometres (12 mi) east of the town of Hallett.

Its name which is derived from the Caroona Creek, a stream flowing within its boundaries, was approved by the Surveyor General of South Australia on 14 June 2005.

[4] A separate proclamation on 18 February 2010 ensured the continuation of “existing rights of entry, prospecting, exploration or mining” regarding the land under the Mining Act 1971 and the Petroleum and Geothermal Energy Act 2000.

In 2011, it was described by its managing authority as follows:[8]Situated on the western edge of the Olary Plain, this park contains a range of landforms from steep rocky ridges and calcrete hills extending to alluvial plains.

The park conserves a representative sample of the transitional zone between the rounded hills of the Mid North to the beginning of the rocky gorge country of the Flinders Ranges.
