The Araglin River is a tributary of the Colligan River, draining part of the Monavullagh Mountains in County Waterford, Ireland. It is known among whitewater paddlers for its natural rock slides, which are the primary draw for those willing to make the trip. The river has a spate character, meaning water levels respond quickly to rainfall in the surrounding hills, and adequate recent precipitation is necessary for a worthwhile run.

The egress situation requires planning. The hike out is significant, and paddlers should be prepared for a demanding carry. Approximately 1 kilometre downstream from one of the notable rapids, there is a hard right-hand bend near a house with a road that may offer an alternative take-out, though this road appeared to be private and has not been confirmed as a viable access point. Continuing downstream eventually leads to a bridge, but this involves a considerable stretch of flat water before reaching it.

The river features at least one falls and a slide section, and the run from below the falls offers a worthwhile stretch of whitewater. Given the spate nature of the catchment, timing a visit after recent rainfall is important, as levels can drop off quickly. The remote character of the river and the logistical demands of access and egress mean this is better suited to paddlers comfortable with self-sufficient river running in a committing environment.
