Blue Ice and Box Canyons: Backcountry Ice Climbing in Ouray & Telluride
A guided, day-long climb into Colorado’s sculpted winter canyons—learn the techniques and chase the blue ice.
There’s a hush that arrives in a high Colorado canyon when temperatures drop and the water that once ran silver begins to glue itself to rock. On a clear morning in the San Juan Mountains, you feel that hush in your boots before you hear the first tap of an ice tool. The canyon narrows, the sky slices in a brighter blue than the valley feels ready for, and great curtains of ice hang like chandeliers from cliff ledges. That’s where you find yourself on a guided day with Mountain Trip: tied in, crampons biting, listening to a guide’s crisp commands as you test a new placement and push past the edge of what you thought you could do.
Trail Wisdom
Layer for sweat and cold
Bring a breathable midlayer plus an insulated shell; you’ll need to manage sweat on approaches and stay warm during belays.
Tuck crampon-compatible boots
Rigid-mountaineering boots that accept crampons keep your feet secure on front-pointing terrain.
Respect avalanche info
Review the local avalanche forecast and follow your guide’s route choices—conditions are variable and can change quickly.
Hydrate and snack often
Cold breaks thirst signals; sip regularly and eat compact, high-calorie snacks to keep energy and focus.

Conservation Note
This region receives high winter visitation; stick to guide-selected approaches, pack out waste, and avoid altering ice formations or diverting water sources.
Telluride and Ouray grew from 19th-century mining booms; many climbing approaches cross landscapes shaped by historic roads and mining remnants.
Seasonal Guide
spring
Best for: Late-season mixed routes, Lower-angle ice, Learning transition skills
Challenges: Thaw-freeze cycles, Unpredictable ice quality
Spring brings variable temps—expect brittle ice in cold snaps and slushy approaches on warm afternoons; pick early or late in the day for firmer conditions.
summer
Best for: Approach hikes, Drytooling practice, Access to alpine rock
Challenges: No solid ice, Limited climbing routes
True ice climbs are rare in summer; use the season for conditioning, drytool practice, and planning future winter trips.
fall
Best for: Route scouting, Training and conditioning, Early-season cold events
Challenges: Shorter days, Initial snow events
Fall offers cooler weather for conditioning; reliable ice is uncommon until deep winter, but early freezes can create isolated routes.
winter
Best for: Peak ice formation, Guided instruction, Full-day backcountry climbs
Challenges: Avalanche hazard, Short daylight and deep cold
Winter is prime season for backcountry ice in the San Juans—expect excellent formations but plan for avalanche safety and frigid temps.
Photographer's Notes
What to Bring
Mountaineering BootsEssential
Stiff, crampon-compatible boots provide the platform you need for front-pointing and secure placements.
Layering System (Base + Mid + Insulated Shell)Essential
Moisture-wicking base layers plus an insulated outer layer keep you warm during long belays without overheating on the approach.
Waterproof Shell JacketEssential
A breathable, waterproof shell shields you from wind, icy spray, and sudden weather changes.
Sunglasses and SPF
Bright sun and reflective snow make eye protection and sunscreen essential even on cold days.
Common Questions
Do I need prior ice climbing experience to join?
No—guided trips are designed for all levels; instructors teach fundamentals from tool placement to rope systems, although basic fitness helps.
Is technical gear provided?
Yes—Mountain Trip supplies technical gear such as crampons, ice tools, helmets, ropes, and screws; confirm specifics when booking.
How cold does it get and how should I dress?
Expect sub-freezing temps; dress in moisture-wicking layers with an insulated midlayer and a waterproof shell, plus warm gloves and a hat.
Are there avalanche risks?
Yes—avalanche hazard exists; guides evaluate conditions daily and choose routes to mitigate exposure, but avalanche awareness and following instructions are crucial.
What about altitude?
Telluride is ~8,750 ft; if you’re coming from lower elevations, give yourself a day or two to acclimate and monitor for symptoms of altitude sickness.
Can I bring my camera?
Yes—compact cameras and phones are fine; protect batteries from cold and use wrist straps to avoid dropping gear on ice.
What to Pack
Mountaineering boots (for crampon stability), Insulated shell (warmth during belays), Water + high-calorie snacks (sustain energy at altitude), Sunglasses + sunscreen (protect against snow glare)
Did You Know
Ouray Ice Park is a community-built ice climbing venue created by diverting water into a canyon to form consistent ice lines; it helped define modern American ice climbing culture.
Quick Travel Tips
Fly into Montrose (MTJ) or Telluride (TEX) for closest access; rent a 4WD or chains in winter; allow extra travel time for snowy mountain roads; expect spotty cell service in canyons
Local Flavor
After a day on the ice, head to Telluride’s Main Street for pizza and a local beer at Telluride Brewing Company or grab comfort food and a soak in Ouray Hot Springs; these towns balance old-west charm with a robust outdoor dining scene.
Logistics Snapshot
Closest airports: Montrose Regional (MTJ, ~1.5 hr to Telluride) or Telluride Regional (TEX, limited flights); driving distance to trailheads typically 20–60 minutes from town; cell service is spotty in canyons; no special permits typically required for guided day trips—check with your outfitter for access rules.
Sustainability Note
These ice features are seasonal and fragile—avoid altering ice, pack out all trash, and follow your guide’s route to minimize trail erosion and disturbance to winter wildlife.
