What I've seen it's all high grade gravel, most of it is pretty smooth, but it can get marked up if the quads get on it when it's wet. There is a brand new bridge that crosses the Beaver River (just a few km's out of CL) that is pretty impressive. To be honest though, I've only seen it in the dark, I was doing 1-1.5 hour rides from the CL end after work in November. At that time I didn't encounter any other users at all. It was exactly what I needed to unwind at the end of the day. CL is so full of pick-up drivers in a rush that I wasn't comfortable riding the 2-3 blocks from my hotel to trailhead. That said, I'm told that it's pretty nice in the summer.
