you cant get there from Spanish fork...j/k. take I-15 south from Spanish until you get to south end of Nephi, at the flying J exit get off, turn left onto highway off end of ramp, take that road south about an hour to salina, cross through 4 way stop to I-70 then east on 1-70 about 15 minutes to Richfield take Richfield flying J exit into town turn right and light at Days inn and park go through town and under freeway, lots of those trails are in that area.
