Epic colonial architecture, libidinous young salsa dancers, Che Guevara murals, white-powder sandy beaches, swaying fields of sugar cane - the images of Cuba are as transfixing as they are timeless. This is an island of unique historical heritage floating amid a sea of encroaching globalisation. Travel in Cuba can involve anything from sipping mojittos at an all-inclusive resort in Varadero to scraping the spit and sawdust off your shoes outside the Casa de las Tradiciones in Santiago. The burgeoning tourist sector rubs up against the Cuba of communist myth.
