Driving from Colorado to Arizona will take you through stunning landscapes and past one of the most iconic natural wonders in the US. The fastest route will take you through Colorado then south through Utah and Arizona. Because the first part of the drive will involve going through mountainous areas, if you are driving between October and April you should consider renting a vehicle like an SUV or another with four-wheel-drive. Adding winter equipment to your rental, if available, as well as roadside protection is also advised. Our fleet also includes a variety of vehicle categories including economy cars, convertibles, sports cars, and luxury sedans. Be advised that not all vehicles are available for one-way rentals.
