According to Aboriginal belief, Tnorala was formed in the creation time, when a group of women danced across the sky as the Milky Way. During this dance, a mother put her baby aside, resting in it's wooden baby-carrier (a turna). The carrier toppled over the edge of the dancing area and crashed to earth where it was transformed into the circular rock walls of Tnorala.

The Reserve is accessible all year round.  A 4WD is recommended for the last 5km drive in to the Reserve.
