It covers a surface area of about 14.1 km² and is one of the largest freshwater resources in the Province. Nearby is Maipo volcano. The volcano and its reflection in the lake forms diamond-shape image, which gives the lake its name. It is known for its stunning beauty. However, few get the chance to see it because it is passable only in February and only via an off-road
Laguna del Maule (volcano) have been compared to the ones of Tronador volcano; additional compositional similarity is found to other volcanoes close to Laguna del Maule such as Cerro Azul and Calabozos. Laguna del Maule stands out for the frequency of rhyolitic rocks, compared to volcanoes farther south in the chain. There are compositional trends in the region of the volcanic arc between 33°-42°, with more northerly volcanoes being more andesitic in composition while to the south basalts are more frequent. All the postglacial activity appears to originate from a shallow silicic magma chamber beneath the caldera, which acts as a trap for mafic
