I'll be riding this route later in June. It's 60 miles with about 6,000 feet of climbing, but the grades aren't steep (well, parts of the 1400 foot climb on the return may hit 7%), and there's a nice mix of climbing and descending. You'll want to pause at some of the overlooks, too. It's really scenic. The highest point on the Parkway, Richland Balsam, is on this ride. The Pisgah Inn is at the halfway mark. They have a restaurant and you can get carryout.
Blue Ridge Parkway downhills are great. They usually have wide sweeping turns, and less than 7% grades, so you rarely need to hit your brakes.
There's two tunnels, and one of them either needs lights or walking your bike through, since you can't see the walls or the the road in the dark.
Here's the one-way
ridewithgps route note--ridewithgps counts every little elevation change towards the total elevation gain. It can be quite exaggerated.
Photos from last Sept. Click the Slideshow button. I started half way up the climb to Richland Balsam (at about the 4 mile mark on the route), instead of Pinnacle Ridge.
Or, you could ride in the reverse direction. Start at the Pisgah Inn, and ride up to the highest point on the Parkway, 22 miles, and return. Then the return trip is more downhill than uphill. Just bring enough water, since you won't find any on the Parkway.

I was thinking about following the top 2/3 of the Assault on Mt Mitchell climb, from where it joins the Parkway, up to the top of Mt Mitchell. But, it's all climbing or descending, with consistent 6-7% grades. I would need to stand up for a lot of the climbs. The road from the Parkway to Mt Mitchell is about 1400 feet in 4.5 miles. There's a restaurant a couple of miles from the top of Mt Mitchell.
