Surrounded by lush natural mangroves and multimillion-dollar residences, this property delivers the perfect balance of privacy, exclusivity, and direct boating access. A standout feature of the property is the grandfathered in 20x24 dock, significantly larger than what current regulations allow. Paired with a 14,000-pound boat lift and existing water and electric connections, for boating enthusiasts, this is not just a convenience, it's a major asset that cannot be replicated today.
