The Mohave & Milltown Railroad Motorized Trail intertwines with a historic railroad grade. This 7-mile trail is designated for OHV and equestrian use and runs parallel to the non-motorized trail. The route is marked with signs and rock cairns. The best season is anytime from September through May. In the event of plentiful winter rain, wildflowers can be abundant February through April.
