Little Mertens Falls is a thundering curtain of water cascading over rugged sandstone walls into a beautiful pool on Mertens Creek, within Mitchell River National Park on the Mitchell Plateau in Western Australia's Kimberley region.

The falls are reached via an easy-to-moderate 1. 6 km return walk from Mitchell Falls Campground, taking roughly one hour and allowing time to explore and swim.

The surrounding area features rock ledges, rapids, natural pools, and Aboriginal rock art sites of deep cultural significance to the Wunambal Gaambera people, the Traditional Owners of the park.

Little Mertens Falls also serves as a stopping point along the longer Punamii-Uunpuu Trail, an 8. 6 km return route that continues past Mertens Gorge to the iconic Mitchell Falls.

Visitors should take care near cliff edges and be aware that saltwater crocodiles are present in the region.
