Downtown Charleston is located on a peninsula, approximately 6 miles in length. My location is in the middle. Three miles southeast to the harbor and three miles northwest to the city line with North Charleston. North Charleston is a separate city. Historic Charleston's tourist area begins approximately 1 1/2 miles from my house. An 18 min walk down King St will take you to the free trolley bus stop. Hop on and off along its route for shopping and viewing historic homes.
