A very different Florida trip than, say, bustling Miami or Orlando, the laid-back Keys may sound a little dull to kids at first. But soon, even the most action-oriented will slip into the 120-mile island chain's gentle pacing and natural abundance of water, fish, and beaches.

The winter or "shoulder" seasons (late fall, early spring) are ideal times to capitalize on the Keys' dry, warm weather. The area used to practically hibernate in the rainier, buggier summer, but in recent years it has become a more year-round attraction. (Because it's so close to water, it's not nearly as hot or humid as Miami.) Getting up and out as early as possible will help you navigate around the less favorable summer conditions.

The weather's the best in November to February, when the average temp is 76 degrees, but highs rarely top 90 degrees -- even in the summer. Shorts, a T-shirt, and comfortable sandals are the dress code year-round in the Florida Keys -- dictated by both the weather and the informal atmosphere. You might need to accessorize with a light jacket or sweater at night in the winter, and you'll definitely need to travel with a rain poncho or umbrella in the summer months. Late summer and early fall are also peak hurricane times in the Keys. Get more weather info.

Although there are small airports in Marathon and Key West with regional airlines flying planes from Miami, most visitors save the considerable expense and enter the Keys by car, which you'll need to navigate the long island chain anyway. After flying into Miami International Airport (MIO) or taking the Amtrak or Greyhound, take the Florida Turnpike extension to U.S. 1 South. It eventually becomes the Overseas Highway, the central road running from uppermost Key Largo to southern Key West.

Like most of South Florida, there's no good public transportation in the Keys. So unless you're planning to ensconce yourself at a single resort for the duration -- in which case you can take the Greyhound bus from Miami to any of the major islands -- you'll need a car. Fortunately, it's easy to get around since the main Overseas Highway is divided by mile markers, starting with 127 and working down to the zero marker in Key West. Most attractions advertise their mile-marking in ads and brochures.

Because the Overseas Highway is a narrow, two-lane road through most of the Keys, and because it takes about three-and-a-half hours to drive from Miami to Key West on a good day, it's best to avoid the area during major festivals. Some of the more family-friendly festivals are listed below.

• Annual New Year's Day Celebration (Jan.)
• Marathon Seafood Festival (Mar.)
• Conch Republic Independence Day Celebration (April)
• Tarpon Fishing Tournament (May)
• Annual Underwater Music Festival (July)
• Key West Summer Food and Wine Festival (Aug.)
• Florida Keys Birding and Wildlife Festival (Sept.)

• Key West is actually closer to Cuba (90 miles) than to Miami (150 miles). It's the southernmost city in the U.S.
• Most people in they Keys are visitors or seasonal residents; locals (known as conchs, like the fish) number fewer than 100,000.
• The Keys got their start in the early 1800s, when Spain awarded the nearly deserted island of Key West to a patriot, who promptly sold it to a businessman for $2,000. It was claimed by the U.S. in 1822.
• Today, a whopping 42 bridges -- including the famed seven-mile bridge -- allow tourists to drive the Overseas Highway from top to bottom.
• Most of the coral islands that make up the chain are narrow; even the big town of Key West is only two miles wide.
