Skyline Drive, starting at the Bountiful, Utah Bountiful 'B'.
Located just north of Salt Lake City is Bountiful. On the mountain range to the East of I-15 you can see the large 'B'. That is the starting point of Skyline Drive. There is a couple acre dirt lot there to park and unload. You can run the 1-1.5 lane wide dirt road, or choose to go up the side of the mountain in to the tighter more 4-wheeler sized trails that will tie in to Skyline Drive.
You could burn tanks of fuel up there blasting around, but the benefit is to get to the top and overlook Bountiful/Centerville and also the Great Salt Lake to the West.
If you don't mess around and hurry to the top, 2hrs would be enough time. Or you could spend a whole day up there. On a weekday you will be lonely, on a weekend you will be climbing over others like the mice in a cage at Petco.
