The Severn River flows through the Granite Belt region of southeastern Queensland and northern New South Wales, where it passes through forested countryside before eventually contributing to the Darling River system via Pindari Dam and the Dumaresq River. The river is characterised by a gentle, unhurried current, making it accessible for recreational paddling including kayaking.

Vegetation along the banks includes river red gums, she-oaks, melaleucas, and bottlebrushes, providing habitat for a wide range of native birdlife. Paddlers can expect to encounter birds foraging on the water surface for insects as well as species soaring overhead. The surrounding landscape is predominantly forested, and the river corridor supports diverse native wildlife.

The Severn River is also fished from kayaks, with Murray Cod being a target species in the area. The river passes near the Severn River Nature Reserve in northern New South Wales, which is home to the rare and endangered Severn River Heath-myrtle plant.

Near Stanthorpe, the river is accessible from private properties such as Severn River Cottages, which encourages guests to paddle on the water. Paddlers planning trips to this area should note that access may depend on arrangements with private landholders, as portions of the river run through private property. Given the gentle nature of the current, the river suits relaxed flatwater paddling rather than whitewater experiences.
