Bushpilot Warm Up Boulder stands as a compelling introduction to bouldering in Rocky Mountain National Park’s alpine reaches. Positioned just left of the prominent Bushpilot Boulder, this spot offers climbers a unique blend of approachable routes and breathtaking surroundings that reward those seeking both challenge and connection with nature. Its location at elevation means climbing here is framed by crisp alpine air and dramatic mountain views, while the afternoon shade offers welcome relief on sunny days.

The boulder features a handful of well-regarded problems highlighted by the accessible yet engaging Warm Up V3 located on the large shield-like feature that dominates the face’s left side. Climbers should come prepared for its firm granite texture and must treat the area with respect – this is a notably fragile alpine environment that demands careful adherence to Leave No Trace ethics. The landings are generally solid, providing a comfortable base for falls and rests, but the ground vegetation and soil require protection from disturbance.

Access to Bushpilot Warm Up Boulder demands mindfulness. It sits within a restricted zone with seasonal closures running from mid-February through the end of July to protect returning raptors and their nests. Off-trail travel above Loch Vale-Sky Pond Trail is prohibited during these sensitive months. Visitors should check current RMNP regulations and area closures prior to arrival. The walk to the boulder involves navigating established paths and solid rock surfaces; off-trail shortcuts are discouraged to preserve the delicate alpine flora.

The climbing experience here is straightforward but satisfying. The routes are concentrated in difficulty around V2 to V6, offering enough diversity to stretch your skills without overwhelming newcomers. The classic problems, including Warm Up V3 (aka V2) and the more demanding Warm Up V6 (previously known as Autopilot), have earned solid reputations throughout the local climbing community for their quality moves and consistent granite texture. These climbs are rated around 3.5 stars and provide a reliable benchmark for climbers gauging their comfort at higher elevations.

Approaching the boulder, the visual focus is on the large shield feature marking the start of the V3 route, a climb that tests balance and body positioning over powerful holds. Weather here is typically stable in summer, but afternoons may bring clouds and cooler temperatures, so dressing in layers is advised. Spring through early fall is the prime season, post-closure and before snowfall, with the best conditions during dry weather windows.

Protection is straightforward; bouldering pads and a spotter are essential given the alpine environment and to protect the surface of landings. Stashing pads on soil is discouraged due to vegetation sensitivity, so plan to store gear on rocks. Chalk marks should be cleaned after climbing sessions, ensuring minimal visual or environmental impact.

Bushpilot Warm Up Boulder is part of the larger Chaos Canyon bouldering scene within RMNP, offering a genuine alpine climbing atmosphere that elevates the experience beyond a simple afternoon session. Here, climbers are welcomed into a wild, quiet space where nature’s rhythms set the pace. The rugged terrain, combined with the intimate scale of the boulder problems, delivers a refined balance between polished effort and connection to the mountains.

Descent is uncomplicated with a straightforward walk off along established trails leading back to the main access points so climbers can focus on planning their next problem or simply soaking in the alpine peace. Note that the presence of raptor nesting closures means timing trips carefully to avoid conflicts and sustain the delicate balance of natural protection alongside recreation.

For those planning a trip to Bushpilot Warm Up Boulder, understanding and respecting the area's sensitive alpine ecosystem is as vital as mastering the climbing moves. Following Leave No Trace principles, packing out all gear and waste, and sticking strictly to trails will preserve the boulder’s pristine setting for seasons to come. Whether you’re warming up your fingers, chasing a strong send, or simply savoring an afternoon in this high-country granite playground, Bushpilot offers an unforgettable slice of Colorado alpine bouldering.
