Mellow Yellow is a standout crack climb tucked within the Leftovers area of Turkey Rocks on Colorado’s South Platte. The route offers two pitches of engaging traditional climbing on the south face, marked unmistakably by a broad yellow flake near the top that catches the eye. This route blends solid crack systems with calm ledges, delivering an experience that’s both satisfying and approachable for trad climbers seeking a straightforward but memorable outing.

Starting just around the corner from the imposing offwidths of Ding and Dong, you’ll find yourself eager to bypass the crowds and dive into a route with a friendlier format. A short scramble brings you to a comfortable belay platform below where your journey begins. The first pitch features wide double cracks leading up to a distinctive left pinnacle, setting the tone with hands-on finger jams and hand jams demanding steady footwork on solid granite.

As you continue upward, the crack system thins, easing into smaller fingers that require precise gear placements and attention to detail. The large ledge near the midpoint of the climb is a perfect spot to regroup, breathe in the cool mountain air, and appreciate the stretch of South Platte foothills around you. From here, the wide yellow flake above signals the final push—a thin crack that test your balance and technique in equal measure.

The last moves bring a satisfying finish, with the option to climb out on an upper crack or veer left to scramble to a walkoff—a versatile descent for climbers who want to avoid rappelling. Along the way, the rock’s texture shifts from chunky holds to smoother, more technical sequences, keeping engagement high without stepping into overly challenging territory. Protection follows a classic trad setup, from small cams to larger placements up to #3 Camalot, ensuring your rack stays practical but versatile.

Expect a climb that moves gracefully between power and finesse. The two-pitch layout allows you to savor the rhythm without rushing, perfect for those who appreciate a blend of exposure and security. The South Platte area offers a rough-and-ready vibe, where solid climbing meets unpretentious outdoor adventure. Whether you're dialing in techniques or simply enjoying a pleasant day on the rock, Mellow Yellow delivers clarity in its approach and pleasure in its execution.

For planning, the scramble to the base is manageable, though the rocky terrain calls for sturdy footwear and attention to footing. Timing your climb during mid to late morning will optimize light and warmth on the south face, while spring through fall brings the best climbing conditions before winter chill sets in.
