We spent the night in Park City and in the morning Landon and Jacob went on a trail run. They went far and fast on the spiro trail. Mark and I walked up the road from our condo and hiked up Sweeney's Switchbacks.
It is a gradual uphill with lots of switchbacks as titled. You go under a ski lift several times and pass by the old lift towers.
It was a pleasant hike in the pines with lots of views of Park City since you are definitely up on the mountain. There were a lot of pretty wildflowers. I'm not sure how far we went but we didn't go to the end of the trail.
