Biscayne National Park
Dade County, FL
Quick: what’s the only county in America with TWO national parks? Raise up, DJ Khaled, it’s none other than DADE COUNTY. Not only is it home to more people with “Made in Dade” tattoos than you’d care to think about, but it's also home to the Everglades and Biscayne National Parks, the second of which is part of the Florida Keys Reef Tract. Here, you can snorkel over shipwrecks, living reefs, and even spy the occasional dolphin.
