The tours operate daily, leaving the Cades Cove Heritage Depot - which is next to the Great Smoky Mountains Heritage Center - at 8 a.m. and 1 p.m.
I found this in the Knoxvile paper--tours started this week. It sounds really interesting. Seniors are $10, Adults $13, and I forgot the child's fare.
It does offer a new way to see the Cove and hear interesting facts that we may not already know.
