Sorry for the late responose! Pine Valley is in southwestern Utah, about 25 minutes north of St. George. It's a stark foresty change from the red cliffs of St. George. This trip was on the northern end of the mountain, more like 40 minutes away, where the terrain is more open and rolling. There are many trails, including the great Summit Trail, which walks nearly 40 miles along the ridgeline - I've yet to do the entire thing, but have done about 15 miles of it.
