The Rainbow Serpent is said to travel underground from the base of the falls to reappear 20 km upstream at the Mill Hole on the Apsley River in Walcha.

Oxley named the Apsley River and wrote in his journal that he was "lost in astonishment at the sight of this wonderful natural sublimity".

In 1902 three men, Ted Baker, Jim McMillan and "Wattie" Joiner built the wooden stairway that zigzagged its way from the top of the gorge to the water's edge.

[3] Quite some time after parts of this stairway rotted and became dangerous, the Walcha Lions Club set about the huge task of erecting a steel staircase and viewing platform to halfway down the gorge.

Since the National Parks and Wildlife Service took over they have constructed additional lookouts and walkways to view and photograph this magnificent gorge and the two falls.

Good facilities are available for caravan or tent campers, including fire wood, toilets, interpretive information, hardened walking tracks, access for disabled people, ten viewing platforms, Aboriginal history, flora and fauna.
