The 30,866-hectare (76,270-acre) national park is located approximately 80 kilometres (50 mi) southwest of Bourke, at the junction of the Darling and Warrego rivers.

[3] Toorale has a broadly flat landscape with extensive floodplains, and smaller areas of low ridges, riparian strips, and two notable peaks.

[3] Small ephemeral lakes (gilgais) occur in depressions and swamps, whilst historic water management practices have created a vast wetland ecosystem on the park.

[3] Outer bends of the Darling and Warrego rivers and tributaries are lined by coolibah open woodland, which extends onto the surrounding alluvial floodplains.

[3] On dryland areas there are extensive woodlands of belah, black oak, western rosewood and leopardwood.
