I have fished in the Park City area a few times. I have fished both the Weber and the Provo and had much better luck on the Provo. My two favorite areas are on the middle section in Heber City and the lower section near Bridal Veil Falls. On the middle section I have had good luck parking by the bridge near the middle of Heber City and working upstream. The spots near the road are heavily fished so I try to stay away from them. On the lower I park on the road that is next to the river below the falls and fish upstream. One interesting thing is that everybody was recommending size 22 and 24 size flies but when the action got slow, I switched to a size 14 orange stimulator and had a fantastic afternoon with 15"+ browns.
