Monterrico Beach, Guatemala. Even though Guatemala a Caribbean country, the beaches are not the attractions that most delight the tourists. And this is a great reason for you to visit them, because they are fairly quiet. But here's another irony of the country: the most popular beaches are on the side of the Pacific Ocean and not in the Caribbean Sea. Monterrico (pictured) and Puerto San Jose are the best known and Iztapa, one of the most exotic - they all have dark sand.
