This is a must see in the summer months!!! The road is paved most of the way with some of it a bit washboardy. We had a compact rental car and it handled it easily. THE VIEWS of the mountain ranges and valleys is incredible and is a must see. We went from the Park City side to the Big Cottonwood side. I think in the future, I will pack a picnic and spend some time along the creek at the picnic sites in Big Cottonwood Canyon! Really great!!!
