We did most of the Doughton Park trails over three days. This was a great hike. We left the car at the Longbottom road parking lot. The first day we did the Cedar Ridge trail up to the Doughton Park campground (where we did leave our tent in the morning, so we didn't have to carry it the first day when the temperature was around 90°F). Cedar Ridge is nice, with some nice viewpoints along the way. The second day, we did the Bluff Mountain trail up to Bluff Mountain, and went down on the Bluff Ridge trail. Contrary to what is written in the guide, this first half of the Bluff Mountain trail is great! The trail goes through open field areas where you have constantly amazing views of the Blue Ridge. This was our favourite part of the hike (don't miss the Wildcat Rocks view). You're never far from the parkway, that's true, but you're not hiking on the sidewalk neither, so it's not disturbing. The Bluff Ridge trail is however very steep and you don't see much. The second night we did stay at the primitive campground on Grassy Gap road (nice river). There are 8 spots there (you need a free permit that you can ask at the Doughton Park campground). The third day, we climbed the Grassy Gap road and came down to our car at Longbottom road by the Flat Rock Ridge trail. The Grassy Gap is very nice, an old and narrow gravel fire road that is now used by hikers and horses. The 1 mile on the Bluff Mountain trail was however frustrating, you're hiking below the parkway and don't see much although you just climbed 1600 feet. So don't hesitate to stay a bit at the Basin Cove overlook and climb the small hill on the other side of the parkway where you have another nice view. We were pretty tired at the end, but happy of our weekend.
