The Canary Islands are a Spanish archipelago and the southernmost autonomous community of Spain located in the Atlantic Ocean, 100 kilometers (62 miles) west of Morocco at the closest point.
It is also one of eight regions with special consideration of historical nationality as recognized by the Spanish Government.
The eight main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, El Hierro and La Graciosa.
Historically, the Canary Islands have been considered a bridge between four continents: Africa, North America, South America and Europe. The archipelago’s beaches, climate and important natural attractions, especially Maspalomas in Gran Canaria and Teide National Park and Mount Teide (a World Heritage Site) in Tenerife (the third tallest volcano in the world measured from its base on the ocean floor), make it a major tourist destination with over 12 million visitors per year, especially Tenerife, Gran Canaria, Fuerteventura and Lanzarote. The islands have a subtropical climate, with long hot summers and moderately warm winters. The precipitation levels and the level of maritime moderation vary depending on location and elevation. Green areas as well as desert exist on the archipelago. Due to their location above the temperature inversion layer, the high mountains of these islands are ideal for astronomical observation. For this reason, two professional observatories, Teide Observatory on the island of Tenerife and Roque de los Muchachos Observatory on the island of La Palma have been built on the islands.
