Playa de Bolonia

Spain's most dramatic Atlantic beach combines towering Roman ruins with pristine, windswept dunes. The 4-kilometer shoreline is backed by a 30-meter-high sand dune system, formed over centuries from offshore sediments, while the adjacent ruins of Baelo Claudia date back to the 1st century BC—exhibiting remarkably preserved temples and a fish-salting factory. the constant onshore breeze (averaging 25 km/h) keeps crowds thin even in peak season.
