Humboldt Peak is the least challenging climb of the Crestones. The standard route on the peak is an exhausting hike along a trail, with rock scrambling (Class 2) near the summit. The trail climbs the peak from the South Colony Lakes basin, accessed from the east side of the range. This basin is a popular site that is also the base for most climbs of Crestone Peak and Crestone Needle. A very rugged four-wheel drive road follows the South Colony drainage to near the Lakes; however, this road will be closed halfway up on October 13, 2009. There is a lower parking lot for two-wheel drive access at the San Isabel National Forest boundary. The climb involves of elevation gain in a round trip when done from the two-wheel drive access point, but only of gain in a 12-mile round trip from the current high-clearance four-wheel drive access point.
