Um its gonna be fucking hot or I would be there but Big South Fork is really nice and its like 2 hrs nw of Great Smoky Mountains up by the Kentucky border - there's two trails there I wanna check off my list but haven't done yet -

John Muir Overlook - you park along a dirt road in Kentucky and its 2.5 mi each way up on a ridge to an overlook above No Business Creek - basically a small holler but it looks nice

O&W Overlook - this one is looking east from south of the "main area" at leatherwood ford and its a bit annoying to access - the closest way (I think) involves descending and then ascending the steepest hardest bits of gorge @ honey creek

so the two OTHER ways are parking at I wanna say its called honey creek horse camp - but basically there's horse trail parking to the west of the overlook ~ 3 mi away from it

OR from the east you can park at a rail trail parking trailhead (that is apparently on a rough dirt road) and walk/bike 2 mi on the O&W rail grade, and then there's a bridge going east to west across Big South Fork and then you have to ascend the gorge to get to the overlook.

And Buzzard Rock has a 180 degree view of Big South Fork from directly above it for a far shorter hike than either of the two previous aforementioned ones.

And Dicks Gap Overlook (your choice of long annoying hike from the bottom of the gorge or very short easy hike + drive to get there on terrifying steep narrow mostly paved road) has a horseshoe bend view of Big South Fork and was quite nice.
