Can anyone help me with today's viewfinder quiz? The question is: "It used to be a haven for poets and intellectuals, but now this island can attract up to 60,000 visitors a day in the height of the season. Its cliffs were once dramatically described as 'rebellious, tumultuous, lyrical, violent, belligerent and revolutionary', but it is perhaps better known for its chic designer boutiques and glamorous bars. Name the island."
