Best winter hikes near Boulder
The best winter hiking near Boulder splits into two kinds: low, sun-exposed foothill and mesa trails like Sanitas Valley and Marshall Mesa that melt out fast and stay walkable in town, and high-country snow up the canyons around Brainard Lake and Nederland for snowshoeing and cross-country skiing.

Winter around Boulder is not one season, it's two. Down low, the sun is strong and the foothills sit in a dry, chinook-prone belt, so south-facing trails shed their snow within a day or two of a storm and you can often hike in regular shoes. Up the canyons, the same storm leaves deep, soft snow that sticks around for months, which is exactly what you want for snowshoeing and cross-country skiing. This roundup sorts the best spots into those two groups. Each place links to its own guide for parking, distance, and current rules, so start here, then dig into the one you want.
Low, sunny hikes that melt out fast
These are the in-town and foothill options for a snow-free or nearly snow-free winter walk. They sit low, catch a lot of sun, and dry out quickly, so they're your best bet on a cold, clear day when the high country is buried.
- Sanitas Valley Trail: A low, sun-exposed valley-floor walk right above town that tends to melt out fast after a storm.
- Marshall Mesa: Open, south-facing mesa trails that dry out quickly, so the mud and ice clear sooner than the shady foothills.
- Rabbit Mountain: Low prairie-meets-foothills terrain northeast of town that stays warmer and snow-free when the higher trails are buried.
- Boulder Creek Path: Paved and plowed through town, so it clears fast and stays walkable when the dirt trails are a mess.
- Wonderland Lake: A flat, gentle loop on the north side of town, and the lake itself sometimes freezes hard enough for ice skating.
Snowshoe and cross-country-ski spots up high
When you actually want snow underfoot, drive up the canyons to the high country. These are the spots to strap on snowshoes or cross-country skis, where the snow is deep, soft, and reliable through the cold months.
- Brainard Lake: The classic winter snowshoe and cross-country-ski destination up the Peak to Peak, accessed from the winter trailhead once the upper road closes.
- Mud Lake: Quiet, snowy loops near Nederland that are gentle enough for a first snowshoe outing without a long drive up a canyon.
- Nederland: The mountain-town gateway to Boulder's high-country snow, with trailheads and services on the way to the deeper winter routes.

Winter hiking near Boulder: what to know
The low trails and the high trails ask for different gear. Down low, the hazard is usually ice, not depth: shaded corners and packed, refrozen snow turn slick even when the trail looks bare, so slip-on traction is worth carrying. Up high, plan on snowshoes or skis and dress for real cold and wind. Either way, the winter sun sets early and temperatures drop fast once it's behind the ridge, so start earlier than you think, pack a warm layer and more water than feels necessary, and turn around with daylight to spare.
Winter hiking near Boulder: FAQ
What is the best snow-free winter hike near Boulder?
For a hike you can usually do in regular shoes, pick a low, sun-exposed trail that melts out fast, like the Sanitas Valley Trail or Marshall Mesa. The paved Boulder Creek Path through town clears the quickest of all. These low foothill and mesa trails hold far less snow than the shady, higher canyons.
Where can you go snowshoeing near Boulder?
Head up the canyons to the high country. Brainard Lake up the Peak to Peak Highway is the classic snowshoe and cross-country-ski area, and Mud Lake near Nederland offers gentler, quieter loops that are friendly for a first outing. Nederland is the gateway town on the way to most of this snow.
Do you need traction or microspikes for winter hiking in Boulder?
Often, yes. Even the low foothill trails ice up in shady spots and on packed, refrozen snow, so slip-on traction like microspikes is worth carrying from late fall through spring. For the high-country snow around Brainard Lake and Nederland, you will usually want snowshoes when the snow is deep and soft.
Are Boulder's trails open in winter?
Most Open Space and Mountain Parks (OSMP) trails stay open year-round, though conditions change fast and some seasonal wildlife closures apply. Up high, the upper Brainard Lake road closes to cars in winter, which is what creates the snowshoe and ski access from the winter trailhead. Always check the specific guide and current conditions before you go.
Can you bring dogs winter hiking near Boulder?
Yes, on the same terms as the rest of the year. City of Boulder OSMP trails allow dogs on leash, and off-leash with a Voice and Sight tag where posted, while Boulder County and high-country areas have their own leash rules. In winter, watch for ice, cold paws, and packed snow, and check each trail's guide before you bring the dog.
