Understand
The 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 the island is still in its infancy, and what is there is small, basic and, thus far, fairly eco-friendly. Some of the places to stay rely on solar and wind power for their electricity, and many have their own wells which draw drinkable water and/or collect rain water. The people are typically friendly, laid back and genuine.
