Ain't No Puppy offers a gritty introduction to climbing the rugged walls of South Fork of St. Vrain Canyon near Lyons, Colorado. This single-pitch trad route stretches 95 feet through a blend of textured corners and wide, jam-friendly cracks that test both your technique and mental focus. As you step onto the ledge from the well-tread approach, you quickly realize this climb demands respect—fractured rock and patches of lichen add a layer of unpredictability to the ascent, keeping the experience rooted in raw adventure rather than polished perfection. The climb begins by threading an awkward left corner where the rock feels brittle and holds are often insecure, challenging climbers to piece together moves with a calculated patience. Progressing upwards, the route opens into a wider crack section, offering more reliable jams and a chance to settle into rhythm before facing the bulging overhang with hard-fought, positive jams that reward determination. Protection relies mainly on hand-sized gear with no need for wide cams, but doubling up on pieces is wise given the sporadic rock quality. Anchoring involves placing a large stopper and a first-knuckle-sized cam to secure your belay on the ledge’s edge. This belay station is solid, but rappelling demands attention—a 95-foot lower-off returns directly to the ledge, while a full 115-foot rappel with a 70-meter rope lands you safely on the ground below. Approaching Ain't No Puppy follows the same trails as the nearby Revocation, beginning with a steady hike into the canyon’s quieter spaces before gaining a flat ledge that narrows and drops away beneath your feet, sharpening your sense of exposure and adventure. Timing your ascent for mid-morning offers balanced sun exposure—early enough to avoid midday heat but still welcoming warmth on cooler days. While the climbing holds mixed conditions, the route’s modest 5.9 rating errs on the cautious side and could become a solid 5.9- with some cleanup and more climber traffic. It’s an excellent choice for trad climbers eager to embrace imperfection, polish their crack skills, and step out of the gym’s comfort zone into terrain where every move counts. Whether you’re scouting a new line or testing your gear placements under realistic conditions, Ain't No Puppy delivers an honest push that rewards steady hands and precise footwork. Come prepared for a straightforward yet stimulating adventure where natural challenges and practical climbing knowledge intersect.
