New Orleans, LA → Key West, FL

Your journey from New Orleans to Key West spans nearly 820 miles of diverse American landscape, beginning on the bustling streets of Louisiana's cultural capital and concluding at the southernmost point of the continental United States. The route primarily follows US Highway 90 east from New Orleans, merging briefly with Interstate 10 through the industrial corridor outside the city before settling into the more leisurely pace of the coastal highway. As you progress through Louisiana and into Mississippi, you'll traverse the Gulf Coast region, passing through charming port towns and across numerous bayou waterways that define this unique corner of America. The drive then carries you through Alabama's coastal communities before reaching the Florida Panhandle, where US 90 continues its eastward trajectory through Pensacola and Panama City.

The landscape gradually transforms as you move east, transitioning from the swampy bayous and wetlands of Louisiana to the pine forests and beach communities of the Gulf Coast states. Florida's nature becomes increasingly evident as you approach the peninsula, with the terrain flattening considerably as you move south. Around the Fort Myers area, the route shifts more definitively toward the Keys, and you'll eventually merge onto the famous Overseas Highway (US Route 1), a spectacular 113-mile stretch connecting a chain of islands with dramatic ocean views on both sides of your vehicle.

The major cities punctuating your route include Biloxi and Gulfport in Mississippi, Pensacola in Florida, and Tampa or the surrounding Gulf Coast communities if you take alternative routing. Urban stretches near these population centers require patience during peak traffic hours, particularly around New Orleans at the start and as you navigate through Tampa's sprawl. However, much of the drive through rural Louisiana, the Mississippi Delta region, and the Panhandle offers open roads and relatively light traffic.

Plan this drive for late fall, winter, or early spring when temperatures remain comfortable and hurricane season is either past or approaching. Summer conditions bring intense heat and afternoon thunderstorms that can impact driving safety, while the Caribbean-bound hurricane season (June through November) occasionally introduces tropical weather complications to the Overseas Highway section.
