The pink-hued cliffs of Mount Castle are trachyte, a
rock more resistant to weathering and erosion than the basalts along the Main Range.
Much of Mount Castle, the forested valley before you and the land on which you now stand, is not national park but freehold land. This Crosby Family property is managed for cattle production while maintaining its natural beauty.
To access this

carpark at the end if the 7km steep and winding 2WD accessible road from the Main Range Goomburra Section park entry (no fee for entry).
