Auld Lang Syne presents a memorable two-pitch climb carved into the heart of the South Fork of St. Vrain Canyon near Lyons, Colorado. The route begins with a gritty right-facing dihedral that demands steady off-finger jams, offering about 50 feet of continuous climbing before you reach a broad ledge. Nature takes its own due here: two stubborn bushes cling to the crack, inviting climbers to navigate not just stone but living challenges. Moving leftward across this ledge delivers some light traversing, passing the overlooked Eric Couldn't Come crack, before you find your next belay station tucked in a second right-facing dihedral.

The second pitch raises the stakes with a mix of corner climbing and face moves, culminating in an imposing off-width to fist-sized bulge that serves as the crux. This bulge isn’t just a physical obstacle—it’s a gatekeeper that tests your technique, patience, and boldness. Beyond it, the route relaxes into ramps and easy mantles clogged with more thorny bushes to negotiate, pushing your balance and route-finding skills before reaching a final belay ledge just shy of the local summit.

The terrain combines the rawness of classic Colorado canyon climbs with pockets of wild character, where the rock breathes age and persistence. Expect gritty textures under your fingers and moments where the natural landscape demands respect beyond the usual climbing protocol.

Protection is straightforward but demands a thoughtful rack: a single set from BD #0.3 to 4 covers the range, with extra pieces between #0.75 and 3 granting a safer, more confident placement strategy on the trickier sections. A complete set of stoppers rounds out the necessary gear, along with single-length slings to extend placements or anchor at belays. Climbers should come prepared with cord and a rappel ring to comfortably set up the rap station for a clean descent.

Access to this climb requires a short hike into the South Fork trail system, where weather and creek conditions can influence timing and safety. Ideal climbing windows span from late spring through early fall when the canyon dries out and temperatures hover in comfortable ranges. Morning climbs benefit from shaded walls, but afternoon sun warms the rock for cooler temperatures on brisk days.

Whether you’re sizing up the crack jams on the first pitch or tackling the daunting OW bulge, Auld Lang Syne offers a gritty, authentic taste of Colorado’s granite personality. It encourages an intimate dance with the rock, demanding a balance of strength, technique, and tactical gear placement amid a landscape that both challenges and rewards every move.
