The village was developed as a holiday destination in Victorian times on the site of a smaller and older farming settlement, and the first steamboat pier was built in 1851. With a resident population of around 1,000, growing to many more in summer, Innellan found prosperity as one of many seaside resorts along the shores of the Firth of Clyde serving tourist traffic primarily coming from the city of Glasgow further upriver, travelling on Clyde steamers.
