The "middle city" of Florida's Gold Coast, Fort Lauderdale sits between Miami to the south and Palm Beach to the north. The city blends nicely with its metropolitan neighbors, and elements of Miami's chic vibe and the affluent nature of Palm Beach are recognizable. But Fort Lauderdale is a destination itself. Operating one of the busiest cruise ports in North America -- more than three million people pass through each year -- helps define Fort Lauderdale as a robust tourism spot. Fort Lauderdale started out as a swampy outpost with a fort, built to protect against the Seminole Indians. The swamps were transformed in the late 1800s into a series of canals by scooping out parallel waterways and creating long peninsulas between them. This created more than 300 miles of navigable waterways (twice that of Venice) -- hence the city's nickname "Venice of America." The abundance of waterways that wind up and down the coast make Fort Lauderdale a boating hot spot, with 42,000 registered yachts.
