Islandia, Florida
Islandia is best understood today as a historic place name tied to the islands of southern Biscayne Bay in Miami-Dade County. Once incorporated as a tiny city centered on Elliott Key and nearby islands, Islandia was dissolved in 2012, and most of the former city area now lies within Biscayne National Park. What remains is one of Florida’s most unusual stories: a never-fully-built resort city that gave way to protected subtropical wilderness.
Situated just north of Key Largo, the former Islandia area includes Elliott Key and neighboring islands along the upper Florida Keys. Elliott Key, the largest island in the group, has a long human history that includes Bahamian and other early settlers who grew pineapples, key limes, and winter vegetables for mainland markets.
About the Former Community
Islandia occupies a distinctive place in Florida history as both an ambitious real estate vision and a conservation landmark. Incorporated in 1960, the city was promoted as the future site of resorts, homes, and a highway connection through the keys. Those plans never took hold. Environmental concerns, the difficulty of large-scale development in the bay, and the eventual creation of protected parkland prevented Islandia from becoming the resort community its backers imagined.
Today, visitors experience Islandia through Biscayne National Park. Most trips focus on boating, paddling, snorkeling, fishing, wildlife watching, and exploring Elliott Key or Boca Chita Key. Primitive camping is available in parts of the park, but amenities are limited and conditions, hours, and availability may change, so it is wise to check current National Park Service guidance before visiting.

Additional Details
Islandia’s story is closely tied to the effort to protect Biscayne Bay and the northern Florida Keys. Large-scale development proposals in the area helped spark opposition from conservationists, and federal protection followed. Biscayne National Monument was established in 1968 and later became Biscayne National Park in 1980. Over time, most of the land associated with Islandia came under federal management, preserving its reefs, islands, mangrove shoreline, and shallow bay waters.
Islandia no longer functions as a town and has no downtown, municipal government, or everyday visitor services. Reaching Elliott Key and the surrounding islands typically requires a private boat, paddling experience, or an authorized tour. Weather and water conditions can change quickly, so visitors should plan carefully, bring supplies, and review current park alerts before heading out.
Elliott Key, about seven miles long and roughly eight miles across Biscayne Bay from the Homestead area, is known for hardwood hammocks, coastal scenery, and a quieter backcountry feel. Native plants such as gumbo-limbo, wild tamarind, and mahogany thrive here, while birds and marine life make the area especially rewarding for nature lovers. For travelers seeking a remote side of South Florida, the former Islandia area offers a rare mix of history, open water, and protected tropical landscape.
