Dramatic cliffs, peaks and spires punctuate views of a vast dry landscape formed millions of years ago. The park protects open woodland, brigalow and key fossil locations.

Cliffs, peaks and spires are prominent here. Thirty million years ago a series of eruptions covered older basalt rocks with lava, creating hard granite formations. Over time, basalt eroded away more easily leaving the spectacular Diamond Cliffs, Marling Spikes and Sydney Heads you see today.

Forming along the Bowen Basin, these volcanoes also produced gold deposits and fertile basalt soils now supporting diverse plant life. Plant communities growing in Homevale include open grassy woodlands, notophyll vine forests, dry softwood scrub, open eucalypt forests and brigalow-belah communities.

Important fossil localities are also present with fossils dating from the Permian period (280-225 million years ago).
