The 'Costa de la Luz' (Coast of Light) is a section of the
Andalusian coast facing the Atlantic Ocean, extending from
Tarifa, at the southernmost tip of Spain, north and northwestward, along the coasts of
Cádiz and
Huelva provinces, to the mouth of the
Guadiana River.

A popular destination for vacationing Spaniards, the Costa de la Luz has, in recent years, become more popular with foreign visitors, especially the French and the Germans. Increasing urbanization and
tourism-oriented development of parts of the coast have had economic benefits, but these trends have also ignited fevered real-estate speculations and some environmental degradation.
Attractions and recreation
Aside from the beaches and the sunshine, there are ample opportunities and facilities for leisure activities like
fine dining,
golf,
kitesurfing,
boating, and other
water sports. The Costa de la Luz is especially noted for the beauty of its protected natural reserves and a number of first-rate natural attractions. Among them are: the
Doñana National Park, where endangered species, such as the
Spanish imperial eagle, also known as Adalbert's Eagle (Aquila adalberti), and the
Iberian lynx (Felis pardina), can occasionally be sighted; the picturesque
Bay of Cádiz; the steeply-pitched shorelines of the southern section of the Andalusian coastline; the salt marshes of
Barbate and the seaside cliffs at La Breña (both within the
La Breña-Barbate Natural Park); and the sprawling wetlands at the mouths of the rivers
Tinto and
Odiel, where there is a profusion of water fowl and, in season, other migratory birds, including storks and flamingos.

History
The Costa de la Luz has a rich history that dates back to the twelfth century BCE. Cultural attractions include
Baelo Claudia, the well-preserved ruins of a small Roman city;
Cape Trafalgar, where, in 1805, in sight of this promontory, the English admiral,
Horatio Nelson, defeated a combined French and Spanish fleet; and the
Rábida Monastery.
At the Rábida Monastery in
Palos de la Frontera near
Huelva,
Christopher Columbus sought the aid of the
Franciscan brothers, hoping to enlist them as advocates for his scheme to launch a voyage of discovery. They introduced Columbus to a wealthy local seafaring family, the
Pinzón brothers, who, eventually, prevailed upon
Ferdinand and Isabella to listen to Columbus's pitch for support. With royal patronage and the collaboration of the Pinzóns, Columbus was able to secure his three ships as well as local crews from the Huelva area. In fact, there is a persistent belief that Columbus settled on his final westward route after speaking to a local sailor named
Alonso Sánchez.
