Seahorse Key is an island located three miles from Cedar Key by boat and is managed by the Lower Suwanee National Wildlife Refuge. It is open to the public about four times per year. Open Houses are great opportunities for the public to experience the peacefulness, history and natural environment that Seahorse Key has to offer. Visitors can also tour the pre-civil war lighthouse. Access to Seahorse Key is available to the public through Tidewater Tours, Cedar Key Boat Rentals and Island Tours, or it can be accessed by private boats during the open house dates.
