Beneath Linn Cove Viaduct
I've posted several photographs from above the Linn Cove Viaduct in the past but this is the first from below it.
If you park in the visitor's lot just off the Blue Ridge Parkway, you can take a short hike through the woods and see the viaduct from an entirely different perspective.
There's a real beauty to the massive structure as the shiny concrete reflects the forest all around it. Once you've taken in the viaduct, you can continue along several other trails that pick their way through the mountains.
