Tourism began in the late 19th century, when a rowing boat could be hired for 25 shillings.[3] It did not become a popular tourist destination until the early 1970s when small chartered passenger boats became more frequent; five were available in 1973 at a price of £3 per person. By 1990, the level of demand had grown to the extent that the Office of Public Works began to organise ten boats departing from four individual harbours.[61]
