Pumpkin Key is the definitive crown jewel of the Florida Keys—a 26-acre private island that offers "domestic Caribbean" seclusion with the logistical DNA of a mainland estate. Strategically positioned within the ultra-secure waters of Card Sound Bay, the island provides total anonymity without isolation. With existing infrastructure capable of supporting a mega-yacht and a 12-home residential enclave, Pumpkin Key is a rare "plug-and-play" development opportunity or a singular family legacy compound. It remains one of the only private islands in the United States connected to mainland power and water while maintaining a 10-minute transit to a private international airstrip.
