Green Knob is located just off the Blue Ridge Parkway a little north of Mt. Mitchell State Park.
It’s a half mile hike from the parkway or it can be reached from the Black Mountain campground which is much longer and more arduous. There’s not much of a view on the way up but the tower is situated to give a spectacular view of the Black Mountains.Inside Green Knob Fire Tower
The tower is open to hikers and slightly more comfortable than the rocks below it. The top of the trail is overgrown in the summer and requires a bit of pushing through rhododendrons. The view is also partially occluded in June, so it’s probably a better trip in early Spring or late Autumn.
