Sleeps Hill Quarry Reserve consists of approximately sixty-nine hectares which includes Council's former operations depot and landfill. The southern section of Sleeps Hill Quarry Reserve is amongst the largest of City of Mitcham's undeveloped woodland reserves with an area of approximately thirty-three hectares. It is situated approximately 1.5 kilometres south-west of the Belair Country Fire Service station. The reserve is irregular in shape with residential development on its north-eastern, eastern and southern boundaries. The majority of its northern boundary is adjacent to the former Lynton landfill. The Trans Adelaide railway forms the reserve's western boundary. Sleeps Hill Quarry Reserve is part of a larger network of undeveloped woodland reserves across the Mitcham Hills.

The reserve is known locally as 'Sleeps Hill Quarry Reserve' and contains the 'Sleeps Hill Quarries Interpretive Trail'.
