Quillota Province in the context of La Calera, Chile

Quillota is a city located in the valley of the Aconcagua River in Valparaíso Region, Chile. It is the capital and largest city of Quillota Province. It is surrounded by the localities of San Isidro, La Palma, Pocochay, and San Pedro. It is an important agricultural center, mainly because of the plantations of avocado and cherimoya trees.

Quillota is connected to the city of La Calera by the small city of La Cruz. Charles Darwin described the area's agriculture and the landscape in his book The Voyage of the Beagle. In nearby La Campana National Park, there is a plaque at a viewpoint commemorating Darwin's visit.

La Cruz (Spanish pronunciation: [la kɾus]) is a city and commune in Quillota Province, Valparaíso Region, Chile.

La Campana National Park is in the Cordillera de la Costa, Quillota Province, in the Valparaíso Region of Chile. La Campana National Park and the Vizcachas Mountains lie northwest of Santiago. This national park covers approximately 80 square kilometres (31 sq mi) and is home to one of the last palm forests of Jubaea chilensis (Chilean Wine Palm), which prehistorically had a much wider distribution than at present. Another attraction is the Cerro La Campana, which lends its name to the park. In 1834 Charles Darwin climbed this mountain, during the second voyage of HMS Beagle.

In 1984, the park, along with Lago Peñuelas National Reserve, was designated by UNESCO as a Biosphere Reserve.
