Plan a trip to Charleston
Charleston, South Carolina is infused with charm, history, and good manners. One of the oldest cities in the country, Charleston was initially founded in 1670 by the English and named for reigning King Charles II. As Charleston grew into an integral port city for the colonies, the city expanded around architecture that is today, still beautifully preserved. Take a tour - either by cycle or on foot - of Charleston's old streets like Rainbow Row to get a broad view of the city’s buildings. Stop by any one of several historic homes for an in-depth story of the families who lived in them. Pick up local art, fixings for grits, and sweetgrass baskets at the Charleston City Market.
