Simpson Falls, Waterfall in Mount Coot-tha Forest, Brisbane, Australia

Simpson Falls is a cascade waterfall on West Ithaca Creek within Mount Coot-tha Forest, about 1,500 hectares of open eucalypt forest forming the south-eastern part of D'Aguilar National Park near Brisbane. The water drops over rock steps in a series of cascades, and the surrounding forest is home to powerful owls, goshawks, eagles, wrens, robins, possums and bats.

The waterfall and surrounding forest became part of Brisbane's protected lands when Mount Coot-tha Reserve was established as a public recreation space. This protection allowed the natural area and its features to be preserved for public access.

The waterfall draws Brisbane residents who come to walk, photograph, and spend time observing the forest around them. It serves as a place where people naturally gather to enjoy nature.

Access is through a 650-meter walking track from Simpson Falls Picnic Area, which has tables, barbecues, and toilet facilities. The path is clearly marked and allows visitors to reach the different cascade levels easily.

Water flow varies significantly depending on rainfall - from gentle cascades during dry times to powerful streams during wet seasons. These changes make each visit feel different.
