"Upper Chaos Canyon offers a challenging alpine bouldering experience above treeline in Rocky Mountain National Park. Climbers will find powerful steep problems and towering highballs framed by exposed talus and breathtaking mountain views, demanding respect for nature and preparation for quickly changing conditions."
Perched high above Lake Haiyaha, Upper Chaos Canyon embodies the raw spirit of alpine bouldering in Rocky Mountain National Park. This spot is not for the faint of heart — reaching the area requires a vigorous hike over talus and meadows that tests your stamina before the climbing even begins. At an elevation of 10,697 feet, the air thins and the landscape opens, revealing a stretch of rock that offers both steep, intense moves and fearless highball challenges. Classic problems like Sunspot’s chalk-lined overhang and the daunting Suicide Season highball stand as milestones on the ascent, while boulderers chase difficult send goals such as Jade, rated V14, placing Upper Chaos firmly on the national stage for elite climbers.
The climbing style here is as varied as the terrain — whether you crave the explosive power needed to conquer the Skipper Roof series or the mental grit to tackle the towering topouts, the canyon delivers with uncompromising character. Not far from the main area, legends like Top Notch at V13 remind visitors that this is a destination where dedication meets alpine exposure. Each problem feels carved from the mountain’s fierce weather and unyielding granite, demanding high-quality pads since landings are predominantly on jagged boulders.
Getting here means starting at Bear Lake and continuing past the Lower Chaos Canyon trail. From Lake Haiyaha’s northern edge, a less-defined path climbs west and upward across rocky terrain and alpine meadows. This approach, around an hour in length, is a workout that rewards with views and solitude rarely found closer to the park’s busier corridors. The route winds past landmarks like Sunspot before pushing deeper into the talus field where the heart of Upper Chaos Canyon awaits.
Given the high altitude and exposed position, weather should never be underestimated. Summer thunderstorms sweep the range with fierce lightning strikes, and fall sneaks in early with snow that can abruptly shorten the climbing season. Bring layered clothing for warmth and protection, along with ample food and water — rescue here would be complicated and slow. The local ethos emphasizes respect for the fragile alpine environment: stay on trails, leave no trace, avoid altering landings, and never stash pads. Rangers are vigilant, and the conservation of this pristine zone is paramount.
Upper Chaos Canyon is a true alpine bouldering jewel wrapped in rugged beauty and demanding responsibility. Climbers find here a blend of raw power, mental challenge, and breathtaking altitude that sets it apart from more accessible bouldering venues. Among the classic climbs, Travesse (V7), Skipper D (V8), and Riddles In The Dark (V10) offer lines that test technique and boldness. The setting and environment amplify that challenge, inviting those prepared for a serious day in the mountains—where every move is earned and every send is a win against nature’s indifferent elements.
The exposed approach across loose talus can become dangerously slippery when wet, and the alpine environment brings sudden thunderstorms and cold temperatures, even during summer. Landings are mostly on boulders, so bring plenty of pads and a solid spotter. Be prepared for an extended return hike and the possibility of rapidly changing weather.
Start early to avoid afternoon thunderstorms common in summer.
Do not stash pads or leave gear behind—rangers and the community actively remove abandoned equipment.
Wear sturdy hiking shoes or approach shoes to safely traverse slippery talus and meadow terrain.
Check seasonal closures due to raptor nesting and respect all access restrictions.
Expect a strenuous approach across loose talus and alpine meadows that requires stable footwear and good navigation skills. Bring multiple pads for protection as landings are mostly atop boulders with minimal padding from ground materials. Weather can change rapidly, so pack layers and extra food and water for safety. Leave no trace principles are strictly enforced to protect the fragile alpine ecosystem.
