Lunar Avenue weaves a tight narrative along the West Ridge’s rugged face in Eldorado Canyon, offering a single-pitch trad climb that demands steady nerves and exact gear placements. While it doesn’t carry the full 's' (serious) rating usually reserved for tougher routes, this 5.8- R challenges climbers with a measured dose of exposure and technical moves that can catch the unwary off guard. The climb starts with confident, secure holds allowing a careful gear placement low on a crack—perfect for setting your rhythm. As you move upward, a small flared seam requires finesse in gear placement, where an offset nut or a tiny stopper refuses to settle comfortably, teasing your judgment and increasing mental engagement. The crux arrives just past this point—a move that leans more on body position and balance than brute strength but is made distinctly more serious if your protection isn't perfectly placed. Here, a #2 Camalot finds a coveted home, offering a solid rest and mental reprieve amid the challenge. The final stretch rewards with straightforward holds to the anchors, allowing for a measured exhale and a moment to appreciate the soaring granite peaks that define Boulder’s climbing heritage. Descending involves a walkoff northbound, adding a mellow finish to a technically satisfying climb. For climbers venturing out, the approach through Eldorado Canyon State Park is well-marked and accessible, yet the route’s unique personality requires a steady hand with trad gear—friends in the #0.5 to #2 range, small offset nuts, and micro cams provide the protection necessary to navigate the subtle cracks and seams. Lunar Avenue strikes a compelling balance—enough spice to keep focus sharp yet approachable for those ready to refine their trad skills in a setting alive with Colorado’s stark beauty.
