Michael and I took this train ride last year and it was wonderful. Ride the railway into TN and enjoy the scenic view of the mountains and river on the way. Stop off at a small town in TN for lunch and relax on your way back to Blue Ridge at the end of your adventure. We highly recommend that you get tickets far in advance because this often sells out.
While here, make sure to take a stroll down Main Street and enjoy the unique shops and eateries. It's what makes Blue Ridge so spectacular. (PS... desserts at the wedding are from the Sweet Shoppe of the South and you can try a few out while strolling Main Street for a pre-wedding taste if you like!) Delicious!
