This seemed to be the closest plantation to downtown Charleston (roughly a 10 min drive).
The paid tour consisted of a tour guide who gave a history lesson of the McLeod plantation for the last few hundred years touching on the life of black slaves before and after the emancipation. The tour was outside, and it was pretty hot and humid on an August day. Be sure to spray yourself with Cutters bug repellent, as everyone in our family got several bug bites on our legs and arms.
After the tour we were able to enter the main house and check out the fully restored 1st floor (no access to the upper floor). The house itself is fairly small, as it was built for a middle-class family. So, don't expect to to see a hugh "plantation" house. Good thing, is that the house is air conditioned!
There's also several small cabins in the back which were the slave quarters. A few of them were open so you can look inside and see the size and conditions.
So in summary, the McLeod site wasn't what we expected in a Plantation home. The history lesson from the tour was interesting, but we were expecting more house tour and less general history.
