Hi Chris, It takes about 2 1/2 hours (160 miles) to drive on I-15 from Las Vegas to Zion National Park . Around eleven hours from Zion National Park to Bozeman , MT, and 14 hours (980 miles) from Bozeman to Minneapolis . I would use Travelmath.com to help calculate the distance, driving time, estimated cost of driving and suggested stopping points from one destination to the other. For example, from Bozeman to Minneapolis, Travelmath.com suggests stops in Billings, Dickenson, ND and/or Fargo, ND. Check it out: Travelmath.com.
