Understand
Great Corn Island was originally colonized by the British, and most native islanders have more in common culturally with other English-speaking Caribbean islands than they do with the mainland of Nicaragua. Many have English surnames.
Tourism on Great Corn Island is still in its infancy as most tourists gather on Little Corn. There are almost none of the things one usually associates with tourists traps tourist markets, huge beachside developments by major hospitality corporations, time-share condos, etc.. The people are typically friendly and genuine.
