Toltén River is a river located in the La Araucanía Region of Chile. It rises at Villarrica Lake, close to the city of the same name. Its major tributary is the Allipén River. From its confluence with the Allipén, the river follows a braided course.

After flowing for about 123 km, the river reaches the Pacific Ocean near Punta Nilhue, where it is about 500 m wide.

Icalma Lake is a lake of glacial origin located in the Andes of the La Araucanía Region of Chile. A hamlet on the southern shore of the lake is also called Icalma. About 3 kilometres (1.9 mi) from the hamlet is Icalma Pass, 1,307 metres (4,288 ft) in elevation and on the border with Argentina. The pass is traversed by a road, unpaved in Chile in 2017 and sometimes impassable during the Southern Hemisphere winter due to heavy snows. Icalma Airport is located 9 kilometres (5.6 mi) northeast of the hamlet and some 8 kilometres (5.0 mi) from the border with Argentina.

Icalma Lake is connected to the Laguna Chica de Icalma (Little Lake of Icalma) by a short stream about 300 metres (980 ft) long. The two lakes together have a surface area of 11.7 square kilometres (2,900 acres). Icalma Lake drains northeastwards by way of a 10 kilometres (6.2 mi) long river named Rukanuco. Icalma Lake and nearby Galletué Lake are the sources of the Bio Bio River.

The Malleco River is a river in Malleco Province, La Araucanía Region, central Chile. It rises in the western slopes of the Andes, within the Tolhuaca National Park and near Tolhuaca Volcano. After passing by Tolhuaca, it drops into a 50 meter waterfall before continuing towards the Pacific. The river is a major tributary to the Vergara River, which is a tributary of the Biobío River. The Malleco Viaduct, built in 1890 and at the time the highest railroad bridge in the world, is the main landmark of the river and a candidate as a UNESCO World Heritage Site.

Quepe River is a river of Chile located in the La Araucanía Region. It originates in the lake of the same name, in the vicinity of Llaima volcano. Then flows about 112 km to join the Cautín River near the locality of Almagro, only a few kilometres upstream of the confluence of the rivers Cautín and Chol Chol, point of origin of the Imperial River.

Villarrica National Park is located in the Andes, in the La Araucanía and Los Ríos regions of Chile, near Pucón. The centerpiece of the park is a line of three volcanoes stretching transversely to the Andean range: Villarrica, Quetrupillán, and Lanín. Other mountains in the park include Quinquilil volcano (2,050 m (6,726 ft)), also known as Colmillo del Diablo, and Cerro Las Peinetas, which lies on the border between Argentina and Chile. It ranges in elevation from 600 m (1,969 ft) to 3,776 m (12,388 ft) at Lanín Volcano.

The drainage divide between the Toltén River drainage basin and the Valdivia River basin runs through the park and marks the boundary between the Cautín Province and the Valdivia Province.
