U.S. Highway 1 leads from Miami to the Keys via the famous Overseas Highway.
The two main airports in the Keys are the seaplane base on Marathon Key ({{ICAO|42FL}}) and '''Key West International Airport''' [http://www.keywestinternationalairport.com/] ({{ICAO|KEYW}}). These are only used by private or commuter aircraft, mainly coming in from Miami ({{ICAO|KMIA}} {{IATA|MIA}}), which is the closest international airport.
Greyhound has service to and from the Florida Keys. There are terminals on Marathon, Big Pine Key, and Key West.
Multiple ferry services are available from Fort Myers to Key West. Most of them are large catamarans that will accommodate 20-30 passengers. Sailing time is about 3 hours.
The Keys (at least the accessible, commercial islands) are connected by US Highway 1. A useful and interesting "quirk" about the linearity of the Keys (and US-1) is that directions to establishments and attractions are locally described by the "Mile Markers" along US-1. If you ask someone how to get to a certain beach or hotel, they will tell you that it is at "Mile Marker 68.5"; many signs and brochures will say "MM 68.5" (of course, there is no mile marker 68.5, this just means that the hotel is halfway between mile markers 68 and 69). These numbers start at zero at the start of US-1 on Key West, so the numbers get larger as you go north.
The '''speed limits''' in the Keys are generally 45 MPH on the built-up Islands, and 55 MPH on the bridges and less built-up islands. There are areas (very built-up strips, or animal sanctuaries) where the speed drops to 35 MPH.
In the Florida Keys, divers can choose from a variety of dive sites. There is wreck diving, reef diving and artificial reef diving with different skill levels from beginner to advanced diving. Water temps peak in the low 80Fs in summer, and can drop to the low 70Fs in winter. Visibility is usually good, typically no less than 50 feet, and you'll see more fish life than you might expect.
Florida Keys scuba diving & snorkeling charters and Key West scuba diving & snorkeling excursions will take you out to the Florida Keys reef for world class diving and snorkeling in the mostly crystal clear and calm turquoise blue waters. Florida Keys dive sites have hundreds of different kinds of Florida Keys tropical fish along with the colorful hard and soft corals and other reef creatures. Diving in the Florida Keys and diving in Key West are two of the most popular things to do in the Keys.

As you would expect, there is a lot of seafood served in the Keys, but all types of restaurants exist. These include most of the staples of American fast-food, mom-and-pop diners, and many kinds of ethnic fare.
The Florida Keys are the birthplace of '''Key Lime Pie''' once made using limes exclusively grown here.
Another Key specialty is '''conch''' (pronounced "konk"), a large crustacean often served in chowder.
