San Juan, PR → Myrtle Beach, SC

Your journey from San Juan to Myrtle Beach is an epic cross-country drive that begins with a ferry or flight to the mainland before you can truly hit the road. Once you're stateside, you'll primarily follow Interstate 95, America's busiest north-south corridor, which will carry you through thirteen states from Florida all the way to South Carolina. Along the way, you'll also traverse portions of US 17 and various connecting highways, but I-95 serves as your backbone for this nearly 1,709-mile adventure spanning almost 29 hours of driving time.

The landscape transforms dramatically as you progress northward from the flat, subtropical terrain of southern Florida through the increasingly diverse geography of the Southeast. You'll begin in the sandy, sea-level lowlands of the Everglades region, then climb gradually into Florida's gently rolling interior before encountering the swampy marshlands of Georgia and South Carolina's Low Country. The elevation changes are modest throughout—rarely exceeding a few hundred feet—but you'll definitely notice the shift from tropical palm groves to pine forests, hardwoods, and eventually the cypress swamps that characterize the Carolinas.

Major cities punctuate your route and offer excellent opportunities to stretch your legs and refuel both yourself and your vehicle. You'll pass through or near Jacksonville, Savannah, and Charleston—three historically rich cities with compelling architecture and compelling detours if you have time. The final stretch into Myrtle Beach carries you through increasingly coastal terrain, with the Atlantic Ocean drawing closer as you approach the Grand Strand, South Carolina's famous 60-mile beach resort destination.

For driving conditions, fall through early spring offers the most pleasant experience, as summer heat and hurricane season can make this drive grueling. The I-95 corridor does experience significant traffic through urban areas like Jacksonville and the Charleston region, so consider timing your drive to avoid rush hours in these cities. Rural stretches dominate much of your route through central Florida, Georgia, and South Carolina, offering peaceful driving between population centers, though services can be sparse in certain sections, particularly through northern Florida.
