Fodor's Expert Review J. N. "Ding" Darling National Wildlife Refuge

More than half of Sanibel is occupied by the subtly beautiful 6,300 acres of wetlands and jungly mangrove forests named after a conservation-minded Pulitzer prize–winning political cartoonist. The masses of roseate spoonbills and ibis and the winter flock of white pelicans here make for a good show even if you're not a die-hard bird-watcher. Birders have counted some 230 species, including herons, ospreys, and the timid mangrove cuckoo. Raccoons, otters, alligators, and a lone American crocodile also may be spotted. The 4-mile Wildlife Drive is the main way to explore the preserve; drive, walk, or bicycle along it, or ride a specially designed open-air tram with an onboard naturalist. QR-coded signs link to interactive YouTube videos and a new Discover Ding app combines social media, GPS, and trivia to make learning on-site fun. There are also a couple of short walking trails, including one to a Calusa shell mound. Or explore from the water via canoe or kayak (guided tours are available). The best time for bird-watching is in the early morning and about an hour before or after low tide; the observation tower along the road offers prime viewing. Interactive exhibits in the free visitor center, at the entrance to the refuge, demonstrate the refuge's various ecosystems and explain its status as a rest stop along a major bird-migration route. Wildlife Drive is closed to vehicular traffic on Friday, but you can still kayak and do tours from the Tarpon Bay Recreation Area.
