As indicated by the marked-off "special use" airspace over Cuba and the U.S. Naval Base at Guantánamo Bay, this particular region of the Caribbean can be especially complicated for flight navigation to and from the United States.

Since 1998, it has been recognized as an important oasis of Caribbean biodiversity and is protected as a National Wildlife Refuge.
