Charleston, SC → Myrtle Beach, SC

The drive from Charleston to Myrtle Beach takes you roughly 113 miles northward along a straightforward corridor that relies primarily on US Highway 17, one of the Southeast's most historic coastal routes. You'll begin in Charleston's downtown area and quickly transition onto either I-526 or US-17 North, depending on your exact starting point, eventually merging onto the scenic US-17 that hugs much of South Carolina's Low Country. This classic two-lane highway serves as your main thoroughfare for the majority of the journey, offering a more leisurely alternative to any interstate option and allowing you to experience the character of the coastal region as you travel northward.

As you progress from Charleston toward Georgetown and beyond, you'll notice the landscape gradually transitions from the urban sprawl and historic charm of the Holy City into increasingly rural Low Country terrain. The geography here is characteristically flat, with elevation changes negligible throughout the entire drive, allowing for consistent, relaxed driving conditions. You'll pass through several charming smaller communities, including the historic port town of Georgetown, South Carolina, where colonial-era buildings and Spanish moss-draped live oaks provide a quintessential Lowcountry atmosphere. The vegetation becomes increasingly pine-forested as you move northward, with occasional glimpses of marshland and waterways that typify the region's natural character.

The drive culminates as you approach Myrtle Beach, where US-17 becomes increasingly commercialized with the typical trappings of a major beach destination—hotels, restaurants, and attractions announcing themselves well before you arrive. Urban density increases noticeably in the final 20 miles, so expect slower speeds and more traffic congestion, particularly through the heart of Myrtle Beach proper.

For the most pleasant driving experience, plan this route during the shoulder seasons of spring or fall, when temperatures are moderate and summer beach traffic hasn't overwhelmed the highways. Winter can bring occasional rain and reduced visibility, while summer transforms US-17 into a congested tourist corridor, particularly on weekends. The drive itself presents no particular hazards or challenging sections, making it an easy, accessible journey suitable for all driving experience levels.
