I started in early afternoon on a Friday on a clear, sunny day. There was small crowds around river, playing and looking for the dino footprints but I didn't see anyone on the trails. Started on Blue trail to yellow trail to scenic overlook. This was challenging but doable for a middle age, not in great shape guy like myself. I could see for miles,(with help of binoculars), up to Chalk mountain where I could make out the cars going up it on Hwy 67, over to the long necks poking their heads up, (even a red T-Rex was visable). To the east I could see the tops of the nuclear plant. I went back to blue trail and followed it further past wildcat hollow, There was some (impressive for north Texas), canyon walls along here and found a small trail leading to a crossing on the river. I couldn't resist soaking my feet in the cool running waters. very popular park, but now know why.
