There is Farmington Canyon as well as the B at Bountiful. I'll be home in a few weeks and as soon as the snow is gone I'd be more than willing to show you around those two areas. I'm sure there are more but I'm not familiar with them.
Farmington is mostly mild trail riding but it's close and it is better than nothing. I love driving out to the back side to the end of the road. I'll go up there in the evening have a beer and watch the deer on the Morgan side of the mountain and head home after sunset. I know there is more to the roads out there to explore which I will have to do.
The B at Bountiful is pretty easy to find and can provide some fun for a little while it would be more fun with quads I'm sure but I have played out there in my TJ for a couple hours at a time.
Avon is a gravel road that connects logan to ogden valley, I live near where it starts here in Eden/Liberty, used to be pretty fun to wheel up there in high school but most of the roads that leave the main road have since been shut down and blocked off, not too much fun anymore, a lowered honda civic could drive it with little problem
