My cousin and I did this trail two days ago. The actual terrain wasn't bad at all but the hard part was staying on the trail. We found that the trail was poorly marked. I don't think we'll be doing it ever again.
This is a great trail with great views. Willow Spring is interesting especially if the water is flowing. Really liked this hike and trails are well kept and dog friendly. Not far from the city I live and you feel like you are a long way from home.
