As you drive south from Miami, the first area you encounter is Key Largo, the longest, largest and easternmost island of the Florida Keys chain. The Florida Keys are measured in terms of Mile Markers and Key Largo extends from MM 90 to MM 106. To the north of Key Largo is Florida Bay and to the south are the Florida Straits and the Atlantic Ocean.

Key Largo is home to two state parks, a national park and a national marine sanctuary. You may notice that there are no soft sand beaches like mainland Florida’s wide, sandy beaches. Instead, the Florida Keys has a living reef that extends its length and is the only living reef in the continental United States.
