The trail book I am currently using says high ground clearance and four wheel drive required. Personally I'm pretty sure any truck or SUV should be able to do this trail. I only went into four wheel drive when leaving, just to be able to use the engine as a brake rather than heat up the pads riding the brakes all the way down.
Microwave towers mark the summit.
Allow between an hour or two both directions. Head west until you reach the Broadmoor Hotel. Take a few trips around their new circled intersection, just to show them how much you appreciate that bright idea. Turn left at the next intersection and proceed around the back of the hotel. Stay to the left and follow around the golf course until you see Old Stage Road.
