“An easy to moderate fourteener with beautiful views of Crestone Peak and Needle.”— Taylor Reilly
Above treeline, the South Colony Lakes and surrounding wildflowers will provide a quiet escape compared to more busy mountain lakes. Crestone Peak and The Needle rise from the lakes basin and will remain in view all the way to the summit of Humboldt Peak. From the summit, you'll be able to see great distances into the Wet Valley to the East, and past the towering Crestones into the San Luis Valley to the West. This trail is fun and makes a perfect route for a first-time fourteener summit, though it is still challenging enough for experienced runners to enjoy.
After running 1.1 miles past Lower South Colony Lake, you'll arrive at the upper and eastern side of Upper South Colony Lake, where the Humboldt Peak Summit Trail begins. This is a good place to take a break and filter and refill your water if you are low. The summit trail rises up the eastern slope of the Upper Lake basin making easy switchbacks to the summit ridge.
The Crestones vertical East Faces will be at your back while making the ascent to the summit, but they are in full view if you turn down trail while taking breaks along the way. Once you reach the saddle on the summit ridge (12860ft.), be sure to check the weather for your final ascent, and take a break if you feel the need. From the saddle, you'll be able see the Wet Valley to the east and the entire South Colony Lakes Basin below you to the south and west. This may not be the summit, but the exposed views are grand, no less.
From the saddle, you are only 1 mile from the summit, but have more than 1,000 ft elevation gain. Start up the west ridge to the east. After 13,600 ft., you'll began to encounter a boulder field which rises for several hundred more feet. Keep an eye out for rock cairns as the trail is easy to lose sight of amongst the boulders. Also, be sure to check your footing as some of the boulders here are unstable. As you gain elevation, you'll be able see over the Crestones to the west and into the San Luis Valley.
Eventually, you'll reach a false summit, though you do not have to go to the top. Skirt below the false summit to the right and scramble up through the rocks to reach the end of the west ridge. Here the trail will take you through a flat area to the true summit. From the summit take in the 360-degree views of the South Colony Lakes Basin, the Crestones, and the Sangre de Cristo Wilderness. When you are done enjoying the summit and are ready to descend, head back down the trail the exact route you came up.
