Blair Athol is located about 6 km (4 mi) north of the Adelaide CBD, South Australia.

Blair Athol borders the suburbs of Gepps Cross, Enfield, Prospect and Kilburn.

In 2000, the portion south of Angwin Avenue and its easterly projection to Main North Road was annexed by Prospect.

The reserve also has two playgrounds, a gazebo, the Kilburn Football & Cricket Club, and a large parking lot.

The South Australian Education Department helped set up the school system in Blair Athol and Kilburn.
