The western shores of Aluminė and Moquehue lakes are the most northern parts of Argentina in the ecoregion of the Valdivian temperate rain forest featuring forests, lush vegetation, and heavy precipitation, especially in the winter season of the southern hemisphere.

[2] The endangered monkey-puzzle tree (Araucaria araucana), locally called the "pehuen", is found here in the southernmost part of its range.

Aluminé Lake is connected with Moquehue Lake, 12 kilometres (7.5 mi) long and 1.5 kilometres (0.93 mi) wide, via a narrow channel about 400 metres (1,300 ft) long.

[4] Lake Aluminé has a developing tourist industry near its banks with trout fishing, boating, and sight-seeing.

A small ski resort is located on the slopes of Batea Mahuida volcano, operated by the Puel community of Mapuche people who inhabited this region prior to the arrival of the first European settlers in the 1890s.
