Río Currhué is a small river in the southwestern corner of Neuquén province, flowing through the Parque Nacional Lanín in the Huiliches department. It is a short waterway, roughly 25 kilometers in length, with a width that ranges between 4 and 8 meters throughout its course. The water is notably clear and supports a dense population of aquatic insects and other invertebrates.

Access to the river is straightforward from Junín de los Andes via Ruta Nacional N° 234, reaching the river after approximately 7 kilometers. A bridge crosses the river at this point, where Ruta Provincial N° 62 — an unpaved gravel road — begins and runs alongside the right bank, providing numerous access points along the river's length toward Lago Curruhué Grande.

Water levels on the Río Currhué drop considerably during mid-summer as temperatures rise and flow diminishes. This seasonal reduction in volume is a practical consideration for paddlers, as the already narrow channel becomes shallower and less navigable during that period. Earlier in the season, before the summer drawdown, conditions are more favorable. Near Lago Curruhué Chico, a campsite represents the primary accommodation option in the immediate area.
