Myrtle Beach, SC → San Juan, PR

Your journey from Myrtle Beach to San Juan is an ambitious 1,709-mile trek that will take you through the heart of the American South before culminating in a Caribbean paradise. From the South Carolina coast, you'll head west on Interstate 95, passing through the Lowcountry's flat, pine-dotted terrain before connecting to Interstate 26 near Charleston. The route then carries you through Georgia and into Florida via Interstate 75, where you'll notice the landscape gradually transitioning from rolling piedmont to increasingly subtropical terrain. The final leg involves heading south through central Florida on I-75 toward Miami, where you'll need to arrange ferry or air transport to San Juan—as this route ends at the Florida Keys or Miami's port facilities rather than continuing overwater.

Throughout the drive's first 900 miles, expect a fairly straightforward interstate experience with moderate elevation changes as you move from coastal South Carolina into Georgia's gentle hills. You'll pass through or near several significant cities including Savannah, Georgia, and Jacksonville, Florida, which offer good opportunities to stretch your legs and refuel. The landscape transitions noticeably once you cross into Florida; the terrain flattens dramatically, and you'll encounter more subtropical vegetation, including vast cypress swamps and palmetto forests visible from the highway. This central Florida stretch is predominantly rural with long stretches of road, so plan your fuel and rest stops accordingly.

For the most pleasant driving experience, aim for late fall through early spring when temperatures are moderate and humidity is lower—typically October through April. Summer months bring intense heat, afternoon thunderstorms, and heavy tourist traffic, particularly around major Florida attractions, making the drive more challenging and potentially slower. Spring break season (mid-March through early April) should be avoided due to congestion. Whether you're embarking on this drive for adventure or necessity, remember that the journey itself is as much part of the experience as your Caribbean destination; allow extra time to appreciate the dramatic shift from Lowcountry marshes to subtropical palms.
