Named for cartoonist Jay Norwood 'Ding' Darling, an environmentalist who helped establish more than 300 sanctuaries across the USA, this 6300-acre refuge is home to an abundance of seabirds and wildlife, including alligators, night herons, red-shouldered hawks, spotted sandpipers, roseate spoonbills, pelicans and anhinga. The refuge's 5-mile Wildlife Drive provides easy access, but bring binoculars; flocks sometimes sit at expansive distances. Only a few very short walks lead into the mangroves. For the best, most intimate experience, canoe or kayak Tarpon Bay.
Don't miss the free visitors center (open from 9am to 5pm), which has excellent exhibits on refuge life and Darling himself. Naturalist-narrated Wildlife Drive tram tours depart from the visitor-center parking lot, usually on the hour from 10am to 4pm.
