I think you are referring to the big levels to bald mountain loop that ends on the parkway? Big levels is a very flat portion of the trail. I recommend going up bald mountain for your first time. It is the most fun direction in my opinion. There are side trails and obstacles for people that want a challenge but almost all of them have an easier path around. The last time I drove it I believe it took close to 4 hours. There are some pretty gnarly mud holes towards the top and places to camp closer to the parkway. Depending on rain you will want a winch going through the water. I had it up to my headlights before. A stock Jeep can easily take this trail just know your rig. There were multiple broken down abandoned vehicles to pass by the last time I was up there.
