At the northern end of the Flinders Ranges, next door to Leigh Creek.

This park is friendly and obliging, clean and rustic.  An unpowered site is $10, and a cabin is $110.  I've used both.  they also do a deal for take-away with the nearby Leigh Creek Hotel, as well as other offers.

I don't know what they charge for a powered site, but it's a popular park.
