Preserving more than half of Sanibel Island for the sake of its renowned bird life, Ding Darling National Wildlife Refuge is named for editorial cartoonist J.N. “Ding” Darling.
In the early 1940s, he actively worked to convince the U.S. Fish and Wildlife Service to purchase the land for conservation when the State of Florida planned to sell it to developers.

About the Refuge
While most visitors come to drive the scenic loop around the refuge, to truly explore the nooks and crannies of this preserve, you have to take to the trails.
With the exception of the Indigo Trail, a 4 mile round-trip out into the mangrove forest on an elevated berm, the rest of the park’s trails are short interpretive walks meant to focus on a specific aspect of this refuge.
Ding Darling is noted for its large migratory bird population during the winter months.
Be sure to stop at the observation deck along Wildlife Drive to scan for roseate spoonbills. Their pink feathers show up well against the dark mud of the marsh.
Take the time to walk the Calusa Shell Mound Trail, a loop around an ancient midden in a tropical hammock.
A separate portion of the refuge, the Bailey Tract, has its own set of hiking and biking trails surrounding a group of ponds created long ago for mosquito control. They’re now an excellent place for birding.
Trails
Calusa Shell Mound Trail Near the end of Wildlife Drive, this accessible boardwalk loops a site revealing the ancient Calusa culture that once flourished on Sanibel Island.
Cross Dike Trail Connecting Wildlife Drive and the Indigo Trail, the Cross Dike Trail at Ding Darling National Wildlife Refuge is an easy paved walk between two impoundments. 
Ding Darling Bailey Tract One of the lesser-known trails at Ding Darling National Wildlife Refuge is at the Bailey Tract, off Tarpon Bay Road. Loop around impoundments with great birding.
Indigo Trail Get to know mangroves for miles and miles on the linear Indigo Trail, open to hikers and cyclists as a parallel route on a levee that connects to Wildlife Drive near both ends.
Red Mangrove Overlook The shortest walk at the refuge, the Red Mangrove Overlook along Wildlife Drive provides a fine perspective for birding and for seeing mangrove crabs up close.
