Dino-Flow appears flat on the map, but that's deceiving: the trail constantly goes up and down very small washes and rock ridges. Purple paint shows the way. There are just a few sections of slickrock, which tend to be knobby and a bit bumpy, but most of the trail is smooth dirt singletrack.
It's never very technical, and it's smoother and more rolling than some of the neighboring trails, but it's not trivial either. There are many options to bail out and run down to the very easy Copper Ridge 4x4
