Cottonwood Peak in the Sangre de Cristo Range is an easy Class 2 walk-up, but with a fairly difficult approach via the forest service road to Rainbow Lake, and beyond to the Silver Lake trailhead. The challenge of this summit is in the drive to reach the TH. A high-clearance, 4WD is required. If you do not have one, you'll be hiking many more miles, from either side of the range. Without 4WD, climbers may want to consider hiking in on the Hot Springs Trail that begins on the west side of the range at the Garner Creek Hot Springs trailhead and heading up Hot Springs Canyon, a route which we have no fist-hand experience with.
