When the weather turns in Charleston
Four institutions within a few blocks stack into a full indoor day: the Charleston Museum, the Gibbes, the Old Slave Mart and the self-guided audio tour at Aiken-Rhett. The City Market's four sheds are roofed. Note that the real street closure risk here is not rain but king tides, which flood Lockwood Boulevard and the Market area on clear days.
Charleston's museums, and which one to pick
On cobbled Chalmers Street, the Old Slave Mart is the only known surviving slave auction building in South Carolina, and it closes Sundays. Aiken-Rhett House is preserved rather than restored, with its urban slave quarters, kitchen and stable block intact behind the main house, which makes it the necessary counterpart to the polished Nathaniel Russell. The Charleston Museum, founded in 1773, claims to be America's oldest.
What to eat in Charleston
She-crab soup is the dish specific to this city: crab, cream, roe and a pour of sherry at the table, and it appears on almost every peninsula menu. Shrimp and grits use Carolina Gold rice country ingredients, and benne wafers, made from sesame brought over in the slave trade, are the local biscuit. Rodney Scott cooks whole hog over coals; Bertha's Kitchen in North Charleston does the soul-food version.
What first-timers get wrong in Charleston
Carriage companies draw their route by lottery at the barn, so you cannot choose which streets you see and complaining changes nothing. Nearly everything on Rainbow Row and the Battery is somebody's house. Park in a city garage rather than hunting metered kerb space, which is enforced strictly. Tidal flooding closes low streets regardless of weather, and July humidity is genuinely punishing.
What things cost in Charleston
Forty-three dollars for the Fort Sumter ferry is unavoidable, since no other boat docks there. House museums cluster around fifteen to twenty dollars each, and Drayton Hall runs higher at roughly thirty. The CARTA DASH shuttle around the peninsula is free. A bowl of she-crab soup is about twelve dollars, and a carriage tour lands near thirty-five per person.
