The Cíes Islands are an archipelago off the coast of Pontevedra in Galicia (Spain), in the mouth of the Ria de Vigo.  They belong to the parish of San Francisco de Afora, in the municipality of Vigo.

It belongs to the municipality of Santa Uxía de Ribeira and is integrated in the Atlantic Islands of Galicia National Park.  It is separated from the mainland by a distance of about 3 kilometers to the north.  It occupies about 190 hectares and has a maximum height of 71 meters ("As Gralleiras").  Almost the entire perimeter of the island is rocky but has three beaches of fine white sand.  Since 2001 it has been integrated into the Atlantic Islands of Galicia National Park. Monte Perdido (in Spanish; Mont Perdu in French; Mont Perdito in Aragonese; Mont Perdut in Catalan, all four meaning "lost mountain") is the third highest mountain in the Pyrenees.  The summit of Monte Perdido (3355 m), located in Spain, lies hidden from France by the seemingly impenetrable peaks of the Cirques of Gavarnie and Estaubé.  It stands in the north of Huesca province.  The mountain forms part of the Monte Perdido Range and is located in the Ordesa y Monte Perdido National Park, in the western part of the Pyrenees, in the community of Aragon, Spain.

It is a tributary to the Segre River, with its confluence at La Granja d'Escarp, not far from the point where the Segre flows into the Ebro River.  The Cinca River flows through a rich agricultural region. The Atlantic Islands of Galicia National Park (Galician: "Parque Nacional das Illas Atlánticas de Galicia" , Spanish: "Parque Nacional de las Islas Atlánticas de Galicia" ) is the only national park located in the autonomous community of Galicia, Spain.  It comprises the archipelagos of Cíes, Ons, Sálvora and Cortegada.  The park covers a land area of 1200 ha and a sea area of 7200 ha .  It is the tenth most visited national park in Spain.  It was the thirteenth national park to be established in Spain. Cortegada is an almost tidal island (it is possible to go walking when the lowest tides happen, but a small amount of water flow does not disappear) in a coastal inlet near Pontevedra in Galicia, Spain.  It is part of the Atlantic Islands of Galicia National Park. Malkumba-Coongie Lakes National Park is a protected area located in the north-east of South Australia about 110 km north-west of Innamincka.  The national park was proclaimed on 31 March 2005 as the Coongie Lakes National Park under "National Parks and Wildlife Act 1972" over a parcel of land previously part of the Innamincka Regional Reserve to "conserve significant wetlands, provide experiences for visitors and ensure that the core component of the Coongie Lakes system was protected."  The national park is located on land that was included on the List of Wetlands of International Importance under the Ramsar Convention under the name, Coongie Lakes in 1987.  In 2014, the national park was renamed as the Malkumba-Coongie Lakes National Park.  The national park is co-managed by the Department of Environment, Water and Natural Resources (DEWNR), the Yandruwandha Yawarrawarrka Parks Advisory Committee and South Australian Arid Lands Natural Resources Management Board.  It is classified as an IUCN Category II protected area. The Ordesa Valley is a glacial valley in Aragon, in the Spanish Pyrenees which forms part of the Ordesa y Monte Perdido National Park.
