J. N. "Ding" Darling National Wildlife Refuge is located on Sanibel Island, Florida and protects 5200 acres of undeveloped mangrove ecosystem. The refuge is named for Pulitzer Prize-winning cartoonist, J. N. "Ding" Darling, who became a major voice in the conservation movement. He conceived of the Federal Duck Stamp program, which raises money for wetland conservation, and illustrated the first stamp. Darling was appointed by President Franklin D. Roosevelt to be the U.S. Biological Survey, the predecessor of the U.S. Fish and Wildlife Service.
The refuge is a great place for families to observe wildlife. Some of the best times to observe wildlife are at low tide, during the early morning hours and during the evening hours.
The 8-mile Wildlife Drive is a good way to explore the refuge by bike or car. There are a series of trails that can explored on foot, including the cross-dike Indigo Trail.
