If you're spending any time in the Charleston vicinity and have a few hours, I highly recommend checking it out. There's also a self-guided walking tour through swamplands, a petting zoo, and extensive gardens.
Here are some pictures.
The live oak-lined driveway to the plantation house.
Slave cabins on the plantation grounds.
Many peacocks wandered around the petting zoo area. This one in particular seemed to enjoy posing for me.
Here's a shot of Bubba, the resident male gator of the plantation.
Fred, a great blue heron.
