It’s no secret that Colorado has some of the best trails around, from alpine lakes to majestic peaks, but some hikes are best kept for winter. Whether you’re planning on snowshoeing through fresh powder, walking to a frozen waterfall or just want a break from skiing, the best winter hikes in Colorado are a great way to keep you moving during the long cold season here.
Come winter, some of Colorado’s popular summer trails become impassable, but many simply transform into snowshoe trails while some ski resorts such as Vail are open to uphill use and others offer dedicated snowshoe and cross country skiing terrain.
You’ll want to read our article on what to wear for winter hiking as you can expect cold temperatures, dry conditions and brilliant sunshine most winter days here. For footwear, a good pair of hiking boots is key and for well-packed snow, they’re all you’ll need in addition to hiking poles. For deeper, unpacked snow you’ll want to bring a good pair of snowshoes and check out our guide to snowshoeing for beginners.
It’s worth taking a look at our article on avalanche safety if you’re planning on tackling steeper slopes in the backcountry, however there are lots of mellow trails to choose from where this won’t be an issue. Colorado is a magical place in the winter months and the trails are quieter than in summer so it’s a perfect time to adventure.

St Mary’s Glacier, Idaho Springs
Distance: 2.4 miles
This hike made our list of best hikes near Denver and in winter, the well-trafficked trail means you can do it in hiking boots, though you might want Yaktrax or Microspikes if you want to cross the glacier itself.
This hike delivers truly spectacular views of an alpine lake and glacier without having to cover much terrain at all. The glacier is really a semi-permanent snowfield located in the James Peak Wilderness, but the views are breathtaking for even the most seasoned Colorado hiker.
To get to the trailhead, take exit 238 from Interstate 70 west and follow Fall River Road to the parking lot. Follow the signposted St. Mary’s Trail and arrive at St. Mary’s Lake after about half a mile. This stunning high alpine lake is an ideal spot to rest and enjoy lunch with fantastic views.

For this part, you may want snowshoes or Yaktrax depending on conditions. From Copper Mountain, take 91 South and park in the big parking lot on the left.
Quandary Peak, Breckenridge
Distance: 6.75 miles
Even Colorado’s easiest 14ers are off-limits in the winter months, with one possible exception: Quandary Peak. This popular peak involves a moderate climb, low avalanche risk (note: not “no” avalanche risk) and easy access. If you’re experienced with hiking 14ers and high altitude hiking, a winter 14er might be within reach here.
Winter is a good time to experience this hike without the hoards of summer visitors, though you’re certain to see lots of mountain goats up here. Park at the trailhead off 851 or use the free shuttle service from Breckenridge and enjoy splendid views from the highest point in the Tenmile Range.
Emerald Mountain, Steamboat Springs
Distance: 3.8 miles
With an elevation of 8,252ft, Emerald Mountain is relatively low compared to surrounding areas, making this a popular hike year-round. Enjoy a snowy trail through thick forest and views of Mount Werner if you make it to the summit.
To get to the Routt Street trailhead, turn west on 13th Street. After a short distance, turn left onto Gilpin Street and then left onto Saratoga Avenue. Take the first right to Routt Street and park at the marked trailhead.
Maroon Bells Scenic Loop, Aspen
Distance: 1.9 miles
In summer, Maroon Bells makes for one of the best backpacking trips in Colorado, but in winter you can still experience the splendor of Colorado’s most photographed vista.
The scenic loop is short, easy and transformed into a frosted winter wonderland come December. Find the trailhead 10 miles west of Aspen up Maroon Creek Road off Hwy. 82 and enjoy a snowy stroll by Maroon Lake with the snow dusted peaks in the background.
Shrine Ridge Trail Vail
Distance: 4.3 miles

Mount Sanitas, Boulder
Distance: 2.1 miles out and back or a 3.2 mile loop
While the other hikes on this list showcase the frosty wonderland that Colorado becomes in winter, Mount Sanitas tends to remain mostly snow-free and is a good option if you just want to get moving in winter. This popular Boulder hike delivers sensational views of town and a heart-pumping ascent.
