If manicured lawns and golf courses aren't your idea of communing with nature, then head to Gumbo Limbo. Named for an indigenous hardwood tree, the 20-acre complex protects one of the few surviving coastal hammocks, or forest islands, in South Florida. Walk through the hammock on a half-mile-long boardwalk that ends at a 40-foot observation tower, from which you can see the Atlantic Ocean, the Intracoastal Waterway, and much of Boca Raton. From mid-April to September, sea turtles come ashore here to lay eggs.
