Mertens Creek is a remote waterway located within the Mitchell River National Park on the Mitchell Plateau in the Kimberley region of Western Australia. This area is characterized by its rugged, pristine wilderness and is part of a vast, ancient landscape. The creek is best known for its spectacular waterfalls, including Mertens Falls and Little Mertens Falls, which are major attractions within the park. Access to this region is extremely limited and challenging, requiring significant preparation and suitable vehicles, placing it firmly in the category of a true expedition-style fishing destination for the most adventurous anglers.
