The trail is quiet and not many people are using it. It is also very dry (Dry Creek). The pay off is the view at the top. Beautiful view of the Tri City area and beyond. Not a great dog trail in the summer due to an abundance of fox tails.

Good day high with nice view of the bay. Half of the trail was shaded and the other half very exposed.
