"How long?" will depend on how much sight-seeing you do. If you drive the portion I described without any stops, it can be done in a day. If you stop to take in all the sights, 2-3 days. I was last in the area about 6 weeks ago and some of the roads were closed due to the flooding that occurred in May.Thank you so much I am planning a large trip around March or April and this helps a lot how long is this and how long did it take you and where did you camp thanks for your help again
As to the camping, there are a handful of dispersed sights on Old 105 which is the west rim of Linville Gorge but they are very popular due to the scenery and go fast. For less primitive camping, there is the Julian Price campground on the BRP near Blowing Rock. I'm sure there are other areas as well so maybe someone with more knowledge will chime in.
