The GSMNP GPS data available at TNLandForms.us includes a "quiet walkway" that starts at the back of the New Found Gap parking lot. The trail is a little more than a 1/2 mile and leads to the 1st over-look on the NC side of the park. Near the end of this trail is a nearly 2 mile long side trail that leads down hill connecting to 441 between the two hairpin turns.
I'm trying to determine if these paths are "official" Quiet Walkways that are maintained well enough that I can expect to utilize them for planning a loop hike.
Basically, what I want to do is park at New Found Gap and hike the AT towards Clingman's Dome, turn south onto Fork Ridge, travel down Deep Creek to Martins Gap and Sunkota Ridge and take Thomas Divide to 441. Then hike along 441 down hill so that I can take these two "Quiet Walkways" back to New Found Gap. That way, I only have to hike along 441 for 1.5 miles. Otherwise, it's about 3 miles along 441 back to New Found Gap.
