Lago Villarrica sits in the Araucania Region of Chile, approximately 780 kilometers south of Santiago. The lake is flanked by the towns of Villarrica and Pucón, with Volcán Villarrica providing a dramatic backdrop visible from the water. The Trancura River drains into the lake from the east, and the lake itself empties into the Río Toltén at its western end, where the volcano remains visible over both water bodies.

For paddlers, the lake serves primarily as flatwater. It is used as a practice area for whitewater kayakers finishing the Trancura River Delta section, where calm conditions allow for roll practice after navigating Class II–III rapids. The SUP experience on the lake involves flatwater paddling, with one described route running from the lake toward Playa Blanca. The Río Toltén outflow offers a progression from flat water to Class II+ moving water, making it a logical extension for paddlers looking for more challenge after time on the lake.

Access to the lake from the Trancura Delta section requires logistical planning. The takeout at the beach is often locked during summer months, and a 4x4 vehicle is needed to cross the Río Plata for the beach takeout; alternatively, paddlers can hike out to the road. Two vehicles or a shuttle driver with specific local knowledge of the access points is recommended for this approach.

The lake is surrounded by forests, and the views of Volcán Villarrica are a consistent feature of the paddling experience. The water is described as clear. During summer months, a Mapuche market near the Quelhue Bridge area offers food and refreshments for paddlers finishing the Trancura Delta run. The town of Pucón, situated on the lake's shore, provides accommodations and services for visiting paddlers.

The Trancura Delta section feeding into the lake is considered appropriate for beginners with a professional instructor or intermediate paddlers building confidence, given its safe eddy lines and mellow character. The lake itself functions as a calm terminus for river runs and a starting point for flatwater SUP and kayak outings.
