Trinidad is one-of-a-kind, a perfectly preserved Spanish colonial settlement where the clocks stopped ticking in 1850 and – apart from the tourists – have yet to restart. Built on huge sugar fortunes amassed in the adjacent Valle de los Ingenios during the early 19th century, the riches of the town's pre–War of Independence heyday are still very much in evidence in illustrious colonial-style mansions bedecked with Italian frescoes, Wedgwood china and French chandeliers.Declared a World Heritage Site by Unesco in 1988, Trinidad's secrets quickly became public property, and it wasn't long before busloads of visitors started arriving to sample the beauty of Cuba's oldest and most enchanting 'outdoor museum'. Yet tourism has done little to deaden Trinidad's gentle southern sheen. The town retains a quiet, almost soporific air in its rambling cobbled streets replete with leather-faced guajiros (country folk), snorting donkeys and melodic, guitar-wielding troubadours.Ringed by sparkling natural attractions, Trinidad is more than just a potential PhD thesis for history buffs. Twelve kilometers to the south lies platinum-blond Playa Ancón, the south coast's best beach, while looming 18km to the north the purple-hued shadows of the Sierra del Escambray (Escambray Mountains) offer a lush adventure playground.
