Mountain Forecast for Mt Sneffels

Below is the full weather forecast for Mount Sneffels from the National Weather Service. I recommend scrolling down to review it thoroughly before you attempt your climb.


The South Slopes Route begins at the Yankee Boy Basin Trailhead. You will need a 4WD vehicle to reach the upper trailhead (2.5 miles round-trip). Parking at the lower 2WD trailhead adds around 5 miles of hiking to the trip (7.5 miles round-trip).


Drive out of Ouray on CO 550 about 0.3 miles heading south towards Silverton. At a bend in U.S. 550 (the San Juan Skyway/Million Dollar Highway), turn south onto County Road 361 (Camp Bird Road). Look for the sign: Camp Bird Mine, Yankee Boy Basin, and Box Canyon Falls. Continue up this road, which -turns from a graded dirt road into a narrow shelf blasted road into the canyons west wall.

The road beyond the basin to the Mount Sneffels trailhead is a steep, rough, rutted road that requires high clearance and low gears. At mile 6, at the confluence of Sneffels, Imogene and Canyon creeks, the road to the left leads to the Camp Bird (gold mine) and Imogene Pass. The road narrows and continues up the canyon of Sneffels Creek.

At mile 6.3 it passes through the site of Sneffels, a town founded in 1875. At mile 6.9, a fork to the left goes to the site of Ruby City and up to Governor Basin. The road to Yankee Boy Basin is rocky from here and continues to climbs steeply for another mile or so into the basin.

As a class 3 climb, Mount Sneffels will involve a good bit of scrambling in steep gullies. I recommend a pair of hiking boots, as their ankle protection will help prevent sprains and twists if you trip while climbing Mount Sneffels. Here are my top hiking boot recommendations.

You should always bring the ten essentials with you on your trip (see the infographic below). This is especially true on a class 3 peak like Mount Sneffels. To carry them all, bring a backpack with 20-30 liters capacity. These are several good backpack options that won’t break the bank. 

While trekking poles are not a necessity on this mountain, I use them myself as they offer many benefits and make hiking easier. If you want a pair, I share my personal favorites here

Mount Sneffels is getting busier and busier every year! As more people attempt climbing Mount Sneffels, it is more important than ever to remember and use these key Leave No Trace practices while you are out in the wilderness.

  • Plan ahead, review the route and pick a weekday or day in September to hike.
  • Stay on the trail, and keep dogs leashed on and off-trail to reduce trampling of alpine grass.
  • Leave your Bluetooth speaker at home and let nature’s sound reign.
  • Urinate off-trail, and pack out your waste – a cathole won’t work at high altitude.
  • Give wildlife a wide berth – 100 meters if possible. If they approach, back up to keep space.
  • Take nothing but pictures, and leave nothing but footprints.

Safe travels, and good luck climbing Mount Sneffels! Learn more about LNT on 14ers here.

Mount Sneffels has a very interesting origin for its name. When members of the Hayden Survey visited the peak in 1874, they likened it to a massive mountain from Jules Verne’s 1864 novel, “Journey to the Center of the Earth.” One of them looked up and proclaimed “There’s Snaefell!”, referring to the Icelandic mountain from the book. The locals’ mispronounced version, Sneffels, became the name shortly after. 

Mount Sneffels is a class 3 climb, but it’s relatively easy, making it a popular choice for those new to this tougher level of climbing. Most of the tough scrambling involves moving up gullies, where rocks can be knocked loose by those above you. Be sure you wear a helmet and move carefully!
