Shark Valley, a 15-mile paved road (ideal for biking) through the Everglades, provides a fine introduction to the wonders of the park, but don't plan on spending more than a few hours here. Bicycling or taking a guided tram tour are fantastic ways to cover the highlights.
If you want to see a greater array of plant and animal life, make sure that you venture into the park through the main entrance, pick up a trail map, and dedicate at least a day to exploring from there.
Stop first along the Anhinga and Gumbo Limbo trails, which start right next to each other, 3 miles from the park's main entrance. These trails provide a thorough introduction to Everglades flora and fauna and are highly recommended to first-time visitors. Each is a 1/2-mile round-trip. Gumbo Limbo Trail (my pick for best walking trail in the Everglades) meanders through a gorgeous, shaded, junglelike hammock of gumbo limbo trees, royal palms, ferns, orchids, air plants, and a general blanket of vegetation, though it doesn't put you in close contact with much wildlife. Anhinga Trail is one of the most popular trails in the park because of its abundance of wildlife: There's more water and wildlife in this area of the park than in most parts of the Everglades, especially during dry season. Alligators, lizards, turtles, river otters, herons, egrets, and other animals abound, making this one of the best trails for seeing wildlife. Arrive early to spot the widest selection of exotic birds, like the Anhinga bird, the trail's namesake, a large black fishing bird so accustomed to humans that many of them build their nests in plain view. Take your time -- at least an hour is recommended for each trail. Both are wheelchair-accessible. If you treat the trails and modern boardwalk as pathways to get through quickly, rather than destinations to experience and savor slowly, you'll miss out on the still beauty and hidden treasures that await you.
To get closer to nature, a few hours in a canoe along any of the trails allows paddlers the chance to sense the park's fluid motion and to become a part of the ecosphere. Visitors who choose this option end up feeling more like explorers than observers.
No matter which option you choose (and there are many), I strongly recommend staying for the 7pm program, available during high season at the Long Pine Key Amphitheater. This talk and slide show, given by one of the park's rangers, will give you a detailed overview of the park's history, natural resources, wildlife, and threats to its survival.
