Gooralong Brook Waterfalls are a series of cascades and falls located along Gooralong Brook in the Serpentine region of Western Australia, roughly an hour's drive south-west of Perth.

The brook tumbles over open granite platforms and through jarrah and marri woodland, producing multiple waterfalls and cascades spread across several kilometres of trail.

The falls are best experienced along the Kitty's Gorge Trail, which follows Gooralong Brook downstream before joining the Serpentine River.

Hikers are treated to an iconic viewpoint above the main Gooralong Falls — where a tabletop granite shelf gives way to a sharp drop — before the trail descends for a closer look.

Flow levels vary seasonally, with the cascades most impressive after good rainfall.
