At the recommendation from a local, we drove the road to nowhere into the Great Smoky Mountains National Park. Along the road we stopped at a view point with great views of the lake and mountains and had a picnic lunch. We continued on the the end of the road where we parked and walked a few hundred feet to the tunnel. It is surprisingly large, and sits in the middle of nowhere. We walked through the tunnel, which was not at all creepy on the sunny afternoon we visited. Most visitors stop at the far side of the tunnel, but we continued on the trail for about half mile. The forest was lush and inviting and the trail well marked. Well worth an explore.
