This summer, Spain's Costa del Sol and the French Riviera promise to be packed--the stretches of sand back-to-back (or butt-to-butt?) full of sun-worshippers from colder climes. Why not look further west for a European holiday, far from the traditional (and well-worn) tourist circuit? Portugal, rich in history of mighty ocean navigation and past epochs of sprawling international empires, is an undiscovered delight. Outside of the capital city of Lisbon, the Costa de Lisboa is marked by gleaming white sand beckoning beach lovers and surfers alike. At the town of Sintra, surrounded by lush forests and the geyser-like eruptions of waves breaking at Boca de Inferno, discover the pastel Palacio Nacional da Pena. Or head to the fantastic southern coast; the Algarve is dotted with splendid coastal resorts and quaint fishing villages lined with brightly colored wooden boats.
