A: The ruins are closest to the second entrance from the paved Riverwalk, Peidmont Medical Trail. Heading in from about 1.25 miles on the pave trail brings you to the second MTB entrance. You head in there and the first trail on the right marked Black or Blue (it's been changed from a black rate to a blue rating, just a bit steep. Anyhow head up that trail on the right and about 50 feet in up the hill you will find the ruins of the Carhartt homestead. It's really not a far hike in but be careful, there's lots of cyclers.
