Rent a canoe, kayak, or take the 40-minute boat tour at this park bordering the Intracoastal Waterway. At 1,500 acres, it is one of Florida's largest urban nature facilities. Extensive boardwalks traverse mangrove forests that shelter endangered and threatened species. A 65-foot observation tower showcases the entire park. At the free Anne Kolb Nature Center, named after Broward's late environmental advocate, there's a 3,500-gallon aquarium. The center's exhibit hall has 27 interactive displays.
