New York, NY → Key West, FL

Your epic 1,564-mile drive from New York City to Key West is one of America's most transformative road trips, taking you through dramatically shifting landscapes as you journey south on Interstate 95 and eventually across the Overseas Highway. From Manhattan, you'll merge onto I-95 South, which will carry you through the densely populated Northeast corridor for several hours as you pass through New Jersey and into Pennsylvania. The terrain here is relatively flat with modest elevation changes, though you'll navigate significant urban congestion around Philadelphia and Baltimore before the landscape gradually begins to open up. Once you cross into North Carolina, the highway curves inland, and you'll notice the terrain starting to flatten considerably as the Appalachian foothills give way to the Atlantic Coastal Plain.

As you continue south through the Carolinas, Georgia, and into Florida on I-95, the elevation becomes increasingly negligible, and the vegetation transforms from deciduous forests to pine forests and eventually to subtropical flora. Major cities like Jacksonville, Florida break up the rural stretches, but much of central Florida's route is surprisingly remote and less developed than you might expect. The real transformation occurs when you leave the interstate near Miami and pick up the famous Overseas Highway (US Route 1), which takes you across a series of bridges and causeways through the Florida Keys. This final 160-mile section is unlike anything else on your journey—you'll be driving over crystal-clear water with islands dotting the horizon on both sides, passing through quirky keys like Marathon and Islamorada before reaching the southernmost point in Key West.

The best time to undertake this drive is from late October through April, when temperatures are moderate throughout the Southeast and you'll avoid the oppressive summer heat and humidity that can make long stretches uncomfortable. Winter months offer pleasant driving conditions, though you should be aware that holiday periods mean heavier traffic, particularly around the Atlanta metropolitan area and throughout Florida. If you're traveling during summer, expect intense heat, afternoon thunderstorms in Florida, and significantly increased traffic around major urban centers. Plan for regular breaks every two to three hours, especially on the monotonous I-95 stretches, and save your energy for the spectacular final leg through the Keys, which deserves slower, more deliberate driving to fully appreciate its unique beauty.
