Mount Barney Creek flows through the Scenic Rim region of Queensland, within and adjacent to the World Heritage-listed Mount Barney National Park. The creek is spring-fed and runs year-round, making it a reliable destination regardless of season. The water is described as crystal clear, flowing through lush forest with small rapids and swimming holes along its course. It eventually connects with the Logan River downstream.

Kayaking is a recognised activity on the creek, with Barney Creek Vineyard Cottages specifically noting it as one of the available pursuits on their property. The creek also supports fishing, with bass, trout, carp, and Mary River cod present. Paddlers sharing the water with anglers should be aware of this activity.

The surrounding area is a biodiversity hotspot, and paddlers may encounter platypus, kangaroos, wallabies, and a wide variety of bird species. The national park is classified as a wilderness area, meaning the environment remains largely undeveloped and natural in character.

Facilities in the area include Mt Barney Lodge and Barney Creek Vineyard Cottages, both of which are situated close to the creek and offer accommodation. Mt Barney Lodge also provides local knowledge, maps, and trail notes for exploring the creeks and waterholes in the area, which may be useful for paddlers planning routes.

The creek passes through terrain that includes gorges, forested gullies, and rocky sections. Stepping stones used by hikers crossing the creek are noted as slippery and unstable, which gives some indication of the rocky, uneven creek bed character paddlers may encounter in shallower sections.
