The South Para River, in the context of paddling, is primarily accessed as a short tributary section from Warren Reservoir, located near Williamstown approximately 50 kilometres from Adelaide in South Australia. The river enters the northeastern corner of Warren Reservoir, and paddlers typically reach it by launching from one of the reservoir's two designated launch sites and paddling across the reservoir to the river entrance at approximately GPS coordinates 34.7013°S, 138.9370°E.

The river section itself is a meandering waterway with tree-lined banks. Fallen trees are a notable feature, creating obstacles that require navigation. Submerged tree trunks are also present, and paddlers can attempt to slide or paddle over some of these before the route eventually becomes impassable further upstream. The character of the paddle is calm and exploratory, suited to kayaks and canoes rather than faster craft.

This section is incorporated into two route options from Warren Reservoir. A shorter loop focusing on the South Para River covers approximately 3.8 kilometres. A longer option that circumnavigates more of the reservoir and includes the river section totals around 9 kilometres return. Both routes pass under an old bridge near the launch point.

Paddling conditions are rated as easy, appropriate for families. Free car parking is available at both launch sites at Warren Reservoir, with more space at the eastern launch site. Toilet and picnic facilities are available on site. Paddlers should check weather and wind conditions before setting out via the Bureau of Meteorology. An approved lifejacket is required. The site is managed by SA Water, and access to the broader reservoir reserve is subject to closure on Total Fire Ban days and during reservoir operational activity.

During warmer months when reservoir levels can be lower, paddlers at the nearby South Para Reservoir are advised to bring a trolley to transport kayaks or canoes to the water's edge, which may also be relevant for launching at Warren depending on conditions.
