4. Hart Island
Sadly not named after Bret "The Hitman", there is some controversy as to whether it was named for its shape, or the English word for Stag -- it's variously been home to POW camps, a reformatory, a missile base, and a burial field for the Department of Corrections. Fun times!
5. High Island
It was once much, much more-terrifyingly named Shark Island.
6. Rat Island
Covered in rocks, mussel shells, and bird sh*t, this adorably named land mass is actually private property owned by a dude who snatched it up and is now hosting BBQs all over it.
7. Twin Island
Don't be fooled: this isn't even actually an island anymore (nice try Twin!), thanks to the landfill connecting it to Orchard Beach and Rodman's Neck.
8. North Brother Island
This is the island where they kept typhoid fever Patient Zero, Typhoid Mary. Maybe don't go here.
9. South Brother Island
Jacob Ruppert -- the former Yankees owner who bought Babe Ruth and was the President of the United States Brewer's Association -- had a summer home here for a while, making it pretty much the boss-est island of the early 20th century.
