Take Colorado 69 south from Westcliffe. Drive 4.5 miles and turn right on Colfax Lane. Drive 5.5 miles to the end of Colfax. Turn right and drive 1 mile to a junction. This is usually the location of the winter closure. Continue straight up the 120 Road for 0.3 mile to the Lower 2WD trailhead. In summer, good-clearance vehicles can continue an additional 2.5 miles to the Rainbow Trail Junction (signed). This is the "trailhead."
