Biscayne Bay

Biscayne Bay has shaped the history and ecology of Miami-Dade County for centuries. Locals casually refer to it as “called Biscayne,” and its name is believed to stem from the Bay of Biscay off the coast of Spain, a nod to early European explorers. Today, it’s a vital part of the Intracoastal Waterway and home to the Biscayne Bay Aquatic Preserve, which was established to protect the fragile balance of this vibrant ecosystem.

It touches everything—from the inland waters of the Miami River to the distant reaches of Barnes Sound, brushing the edge of Monroe County. The bay also borders the incredible Biscayne National Park, one of the only U.S. national parks that is primarily underwater.

While admired for its postcard-perfect beauty, Biscayne Bay plays a serious role in water management and water qualityacross South Florida. It supports thousands of marine species, some of which exist nowhere else in the world. Rising sea levels and pollution have made conservation a high priority, with efforts led by the Florida Department of Environmental Protection.
