The Canary Islands lie off the coast of Africa in the Atlantic Ocean and include the islands of Tenerife, Lanzarote, Gran Canaria, La Palma, La Gomera, Fuerteventura, and El Hierro. Lanzarote experienced volcanic eruptions in the 18th-19th centuries that transformed the landscape, forming the volcanic mountains and national park of Timanfaya. Gran Canaria is the most cosmopolitan island with art, culture and beaches. Fuerteventura has the longest beaches and a peaceful atmosphere.
