Eastern Sambo Reef is a research-only Key West bank reef.
Eastern Sambo Reef is a shallow spur-and-groove bank reef south of Key West. The site sits inside a research-only special-use area, so casual entry is not allowed and any visit requires authorization. Its low-relief coral structure and exposed reef line make it a protected reference point rather than a normal recreational stop. The broader Sambo reef system is known for reef fish and other lower Keys marine life when access is permitted.
