Calgardup Cave is a rather natural cave, as it does not have electric light. It was equipped with steps and boardwalks in order to protect it and prevent further degradation. The path leads down into the cave on a long flight of steps to a depth of 27 m. Here the path branches into a left- and a right-hand section. The right-hand section has a calm cave lake which reflects the stalactites of the ceiling.

A special feature of Calgardup Cave are the roots of the red gum trees (marri trees) and other plants growing above the cave. The roots are dangling down into the cave to collect the humidity of the cave, some even trail into the water. The trees are a source of nutrients and basis to many of the troglobionts which live in the subterranean lake.
