It’s a beautiful place. I actually drove past the trail head parking lot this morning going to the family farm around daylight. The parking lot was almost full.
if you go, make sure you don’t park where there are no parking signs. Not trying to be funny but during the fall, it happens and you will get towed. I’ve seen cops have 6-8 tow truck lined up and hauling cars off. There’s a shuttle service too but not sure how that works but it’s probably on the Roanoke County website.
There is a new bridge from the parking lot over route 311 to the trail. I haven’t been in years since I did trail runs but, depending on your condition level, it’s moderately difficult and maybe a 4 mile trip each way.
I highly recommend being at the knob before daylight or near sunset, it’s stunning if the weather cooperates.
You can also do a much further hike with two vehicles from tinker cliffs to McAfee’s
Dragon’s tooth is another worthy option just down route 311
