This highway is for the skilled mountain driver. Lots of sharp curves, cliffs, rapid ascent and very rapid descent. 11000Ft at the summit and the views are fantastic. We were very fortunate as the leaves were almost at peak....Be sure to take the trip up to Guardsman Pass from Park City. Incorporate the trip down to Brighton and make sure to hike around Silver Lake and up to the twin lakes. When finished, cap you trip off with a drive back up to Gurardsman Pass and then to Midway...Well worth while and a drive to remember.
