The Taponga River is a small river originating from the Torbreck Hills and Mt Torbreck, eventually flowing into the Big River just above the Big River bridge. The river is characterized by moving water with a mix of grade 1 rapids interspersed with sections of tree-lined banks, giving the paddle a pleasant, natural feel.

Access to the river is described as difficult overall. The most practical put-in is from the Big River road, paddling downstream to the confluence with the Big River. Those wishing to start from a higher point on the river can access it via Gilettes Track, followed by a short hike through the bush down to the water. The take-out is at the confluence with the Big River.

The recommended section beginning from the Big River road starts with a single grade 2 rapid, after which the character of the river settles into predominantly grade 1 moving water. The combination of small rapids and tree-lined banks makes for a varied paddle on what is otherwise a compact waterway.

Timing is an important consideration for this river. Paddling is best undertaken after local rainfall, and conditions are considered suitable when the Big River gauge is reading above 1.1 metres. Given the river's small size and dependence on rainfall runoff, flows can be expected to be unreliable during dry periods.
