Boulder Mountain Highway is a 30 mile trail located near Teasdale, UT. The trail is primarily used for scenic driving and is accessible year-round.
My last trip on this Hwy was July, 2009, in a Allegro Bay RV. I did it in 1992 pulling a 29' fifth wheel trailer. This road shows you how gutless those vehicles really are! Beautiful drive, however.
I make this drive all the time when I live in Utah... absolutely beautiful.
