The standard route for climbing Snowmass Mountain has the distinction of being the only 14er that is usually summited as a snow climb. The large snowfield on the east slopes holds snow late into the summer, providing an easy to climb avenue to the summit. Beware of the rocky summit ridge, which has plenty of class 3 scrambling waiting for you after your ascent up the snow. Prepare for your climb of this unique Colorado fourteener with this free Snowmass Mountain route guide below.

Climbing Snowmass Mountain: Fast Facts

Climbing Snowmass Mountain - Northeast Ridge Route

Due to the extremely long approach, nearly all parties climbing Snowmass Mountain do so over two days, with an overnight at Snowmass Lake. Start out from the trailhead south and pass through several gates (be sure to close them). A mile and a half in, stay left at a junction and keep hiking.

A little over 6 miles in, around 10,000 feet, come to a large logjam along the creek. In spring months you may find it impossible to cross, but when water is low it should be easy enough to do. Take your time crossing to the other side. 

Follow the trail south before taking a few switchbacks and re-entering the forest. After a mile, stay straight at the next trail junction you come to. At long last, 8 miles in, you’ll come to Snowmass Lake. If you spend the night here, find a site on either side of the creek. 

After crossing the creek, pass through a short section of forest to reach a clearing near the lake’s shore where you can view the way forward above the lake.Take a small trail in the clearing along the lake southwest to reach the west side of the lake. Head west to reach a boulder field, and begin climbing it by following cairns and trail segments. 

Near 11,300 the gully turns to scree and dirt. Continue to carefully ascend, taking your time as it is steep and loose. The slope eventually lessens around 11,900 feet, at which point you should cross and head towards Snowmass Mountain ahead of you. The rest of the trip climbing Snowmass Mountain is best scaled when there is firm stable snow, usually between April-May and June-July.

Looking out at the summit, you should aim for a large hump to the left of the main peak, which provides the easiest access to the summit rocky ridge. There is a break to the left of some cliffs you should aim for, usually filled in with snow. Climb up to the ridge.

Pass over the ridge to the west side of the crest and begin to scramble up towards the summit. There will be plenty of class 3 scrambling and exposure along the remaining Snowmass Mountain route. It may be easier at times to scramble up on the crest itself. Dip back down eventually and scramble up to a large rock rib blocking view of the summit. Find a break in the rock towards the center and scramble over.

Pass under some larger rocks and aim back up to come to the final pitch. Be careful, as the rock here is loose and has taken lives before. Tests your holds and take your time, scrambling up to the summit.

From the top enjoy your view and accomplishment. Be sure you head down with plenty of time to reach treeline by noon thunderstorms. I hope you enjoyed my Snowmass Mountain Route Guide. Good luck climbing Snowmass Mountain, and safe travels on the trail!

Snowmass Mountain is named and known for the large snowfield on its lower slopes. It’s got one of the longest approaches of any fourteeners, clocking in at nearly 22 miles. You’ll need technical gear to climb this peak, including an ice axe and crampons, unless you wait until the snow melts (which is not recommended).

Climbing Snowmass Mountain and other of Colorado’s high peaks are inherently high-risk, dangerous activities. There is a significant risk of injury or death, even with proper planning and experience. Those using my guide accept all risks associated with climbing 14ers and do not hold this website or any information they obtain from it liable for any accidents or injuries that occur while engaging in these activities on Colorado’s high peaks. It is each hiker or climber’s responsibility to research their route carefully, bring the ten essentials, and practice other safe practices, though even these precautions do not eliminate risk and danger. Visit these summits at your own rosk.
