Spent a day on a quad in the Logandale/Valley of Fire area.
Low power. cheap sport quads as a tour offered at every hotel. Bus pulls up to hotel- hour and a half out to location-orientation takes forever and then mostly single file riding- constant stopping to wait for stragglers- like being on a tethered pony ride. Side x side follows doubling as a cold beverage station-lunch pick-up and first aid emergency transport vehicle.
Or if you have a car-you could try something like this
