The Sangre de Cristo Mountains are always a good setting for a scenic workout. On this trip we did an out and back ridge run starting from the Hayden Pass Road, climbing over three twelvers. The Hayden Pass Road gets quite rough near the top (at least on the west side) and we stopped short of the pass at roughly 9,200 feet in my stock 4Runner. Large boulders, some recently fallen and impassable, littered the road above that. Lower clearance vehicles should be able to easily make it to about 9,000 feet. Round trip stats for the day were 10 miles & 5,200 feet and there were no difficulties along the ridge.
