The Backflip route marks an engaging path for trad climbers seeking a blend of solid crack climbing and route-finding on Lumpy Ridge, nestled in the Estes Park Valley of Colorado. The climb begins just east of a prominent 100-foot flatiron that leans confidently against the face, a landmark that owners of the Bookmark Pinnacle call home. From the trailhead, you’ll traverse a moderate approach that delivers you to a right-facing flake—a clean, inviting feature that sets the tone for the climb.

Pitch one launches you into classic 5.8 jamming, with excellent liebacks and hand jams that reward technical finesse and body positioning. This initial section feels like conversing with the rock’s personality—balanced, reliable, and steady. After topping out this flake, pitch two eases into an accessible corner leading to a long ledge, giving climbers a moment to catch their breath while soaking in the surrounding forested ridges and distant peaks.

Pitch three is where the route distinguishes itself. You face two clean, thin dihedrals; Backflip takes the right-hand option. A demanding undercling moves you right as the dihedral turns roof-like—here, a well-earned 5.8 effort feels more serious, rewarding keen attention and precise footwork. Variations add layers of challenge: one allows you to tackle a 5.9 roof, stepping into a crack that connects with the nearby Romulan Territory route, while another offers a slender 5.9 dihedral pushing the technical envelope for those seeking a stiffer test.

The final pitch (pitch four) wanders up and around cracks before settling into easier terrain. Though rated around 5.8, this section offers mixed quality climbing and a slight loss of the rock’s previous sharpness—a reminder that even thrilling adventures possess moments of calm transition. Nearby, an original 5.9 seam looms, now absent of fixed protection but reportedly secure enough with micro gear for the bold.

Access to the route requires a moderate hike around the flatiron’s east side, following well-marked paths with occasional brush and rock steps. The approach rewards with a sensation of stepping away from Estes Park’s bustle and into the raw, rocky character of the Lumpy Ridge Wilderness. Dress for variable alpine conditions and carry a rack suited for traditional placements; Backflip’s protection calls for a standard rack, though confidence in gear placement will sharpen your experience here.

In the broader context, Backflip reflects the rugged spirit Lumpy Ridge offers to climbers—a mix of moderate technical moves etched into reliable granite, punctuated by occasional challenges that tease out skill and confidence. The route invites a wide range of climbers, from those wanting to push into low-5.9 climbing to those perfectly content with classic 5.8 crack climbing. Being part of a popular climbing zone means a sense of community and safety in numbers, yet the route retains an aura of discovery with its less-traveled corners and complex features.

Timing your ascent matters. Early morning light favors the east-facing start, while afternoon sun warms the ledges on pitch two and three. Summer mornings are ideal, not only for light but to avoid afternoon thunderstorms that Colorado’s high country often delivers. As always, a keen eye on weather and conditions can make all the difference between a rewarding climb and an uncomfortable day on the rock.

Descend carefully along the eastern side, following a broken but navigable down-climb to the base, or rappel where conditions suggest. Familiarize yourself with the descent route before committing to ensure a smooth exit. This route combines accessible adventure with subtle demands, encouraging respect for the rock and preparation for shifting alpine weather.

Backflip delivers a classic Colorado trad experience, inviting climbers to test their crack skills amid scenic mountain settings. It’s a climb that balances solid, usable protection, engaging pitches, and moments that reward the thoughtful climber ready to read the subtle changes in the granite’s face.
