If you enter Everglades National Park via the Ernest Coe Visitor Center, you’ll hit the mile-long Anhinga Trail, full of wildlife like alligators, herons, and egrets amid the sawgrass. Nearby there’s also the Nike Hercules Missile Site, a cold war relic that people who like thinking about how close we came to blowing each other up will probably enjoy. Join a tour from the Daniel Beard Center at 2 p.m. any day of the week.
