Keewaydin Island is a primary barrier island located off the coast of Naples, in Collier County, Florida, United States. It can be reached only by boat.
It is managed by the State of Florida's Coastal Office, in cooperation with NOAA, within the Rookery Bay National Estuarine Research Reserve. Keewaydin Island is monitored nightly for Loggerhead turtle nesting activity by The Conservancy of Southwest Florida.
The Keewaydin Island shoreline has been mapped annually since 1997 in an effort to document shoreline change. The shoreline is also mapped after significant storm events. Mapping is done by collecting Global Positioning System locations along the dune-line and then downloaded using Geographic information system software.
