Passage Key National Wildlife Refuge

---

Established in 1905 by President Teddy Roosevelt, Passage Key's purpose is to preserve nesting colonies of native sea and wading birds. 

Originally a 60 acre mangrove island that featured a fresh water lake, Passage Key was almost entirely destroyed by a hurricane in 1921. It is now a low lying sandbar that fluctuates in size from one to 30 acres.. Due to its importance as one of the last undeveloped barrier islands in Tampa Bay, it is closed to public use.
