Mount Sneffels: Yankee Boy Basin 4x4 Trailhead Map

"Sneffels is often said to be Colorado's best and most beautiful mountain," writes Matt Lemke on SummitPost.org. This aesthetic peak features "symmetry, spires, pinnacles, rugged ridges and beautiful slopes of aspens and flowers," according to Lemke.

Description

The route mapped here is the easiest route to the summit of Sneffels, also known as "the Queen of the San Juans." The approach follows a mellow trail winding up a valley, but don't worry—the climb will soon get much more difficult. Shortly after you pass 12,600 feet, you'll be faced with a loose scree slope without a defined trail. Here, you'll have to climb straight up the mountain, making for the Lavender Col, a saddle resting at 13,560 feet. "If you felt it was very difficult to get to this point, you may not be ready for the remaining climb, and this may be a good place to turn back," cautions 14ers.com.

From the col, you'll begin climbing the upper gulley toward the summit. Don't expect to follow a defined trail here, either, so be prepared to climb straight up the scree or snowfield. If you're climbing early enough in the season for the gulley to hide a snowfield, crampons and an ice axe are recommended. Roughly 30 feet before the top of the gully, turn left and scramble through "a small 'V' notch, which provides the easiest access to the summit," according to 14ers.com. After the notch, only a short rock scramble separates you from the summit of this beautiful mountain!

Access Note:

The route shown here begins at the end of the 4x4 road where the singletrack begins. However, note that the 4x4 road to access this point is very steep and technical. Only full-equipped jeeps can generally reach this trailhead—don't expect a full-size stock pickup truck to be able to make it this far.

If you have to begin below this point, there is a trailhead parking lot ~1.6 miles below, and the end of the true 2WD road is 2.7 miles below.

Difficulty

Extreme

Scrambling up mountains and along technical trails with moderate fall exposure. Handholds are necessary to navigate the trail in its entirety, although they are not necessary at all times. Some obstacles can be very large and difficult to navigate, and the grades can often be near-vertical. The challenge of the trail and the steepness of the grade results in very strenuous hiking. Hikes of this difficulty blur the lines between "hiking" and "climbing".

High Exposure

3 out of 4

Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.

Remoteness

4 out of 4

In the high mountains or remote conditions, all individuals must be completely autonomous in every situation.
