The name of Rio Mar Flagler Beach is Spanish for “River Sea”, a quite appropriate name considering that the upscale neighborhood does indeed lie in between a river and the eastern coastline that overlooks the Atlantic Ocean.  As an added perk for choosing to live in one of the gorgeous Rio Mar homes, this neighborhood happens to be right across from the coastline of Flagler Beach itself which further adds to the appeal of choosing Rio Mar real estate.  Speaking of which, the neighborhood is comprised of a fairly balanced mix of single family homes and estates.
