As early as 1928, tourism promoter Rodolfo Lussnigg began promoting the coastal area of Almeria as the 'Costa del Sol'. Since then that term has been attached to the coast in Malaga province. Costa de Almeria extends 217 kilometres from Pulpi, on the border with Murcia, to Adra, on the border with Granada. It is a coast of contrasts. Parts are soaring cliffs and isolated bays, such as those in the Cabo de Gata-Nijar Natural Park. Some are wide expanses of sandy beach backed by dunes and marismas, such as those at Almerimar. Of all the costas of Andalucia, the Costa de Almeria is probably the least exploited from a tourist point of view.
