Driving is a massive cross-country journey of over 2,600 miles, typically taking 40 hours of driving time via I-80 West and I-15 South. Rail travel is not a practical option for this route as there is no direct service to Las Vegas.
Total Distance: Driving distance 4,200 km, straight-line air distance 3,600 km.
