Back in Yaks offers an accessible slice of trad climbing in the heart of Colorado’s iconic Flatirons, making it a useful addition to any climber’s day in Boulder’s famed granite playground. Gracing a clean rock face just steps from the more popular Back in Slacks, this single-pitch route measures about 55 feet and moves through a sequence of approachable terrain that rewards solid footwork and steady gear placements. Starting just right of Back in Slacks, the route climbs a smooth face punctuated by two shallow huecos that add texture beneath the Power Bulge area. The climb then follows a faint rib, leading into a lichen-flecked hand crack where hand-sized cams can be confidently set. While this crack peters out below a small bulge, the next section requires a delicate traverse on crimps around the bulge to a large flake—a feature that offers a welcome rest and secure holds before finishing up a slab reminiscent of Back in Slacks’ finale.

Though often enjoyed as a toprope, climbers with a mind for a tick can attempt it on lead using appropriately sized protection. The route’s 5.9 rating feels approachable for those ready to push the upper end of moderate trad, but be prepared for a short, exposed 5.8 move to place the crucial gear in the hand crack if leading from the ground up. What Back in Yaks lacks in fame, it makes up for in its straightforward accessibility and the chance to sharpen gear skills in a less crowded setting. The granite itself is solid, with lichen marking the quieter sections and clean edges demanding precise movement.

Approaching from The Hand climbing area, this route is a quick hit that plugs nicely into a bigger day of climbing in Boulder’s Flatirons. The exposed slab finishing section faces west and catches afternoon light, so morning or early afternoon ascents provide cooler conditions and better friction. The granite’s texture affords consistent foot holds, though vigilance in securing protection at the bulge and flank is key. Wear climbing shoes with reliable edging support and bring a small rack focused on hand cams, particularly sizes 0.4 through 3 Camalots, to confidently protect the crux sections.

Being a short climb with relatively moderate difficulty, Back in Yaks is well suited as a warm-up, an introduction to the area’s trad style, or a side route if the more popular climbs near the Flatirons are booked up. Hydrate well and plan for a 10-15 minute approach from the main trailhead. Sound footwear and a helmet are recommended due to loose rock potential at the base. Keep an eye on weather; afternoon thunderstorms are common in this region during summer months.

In sum, Back in Yaks invites climbers seeking a modest but satisfying single-pitch trad experience within Boulder’s celebrated Flatirons zone. Simple in structure but demanding careful gear placement and delicate footwork, it rewards focus and offers the thrill of climbing granite shaped by westward light and mountain wind. If your goals include making the most of a day in The Hand area while practicing fundamental trad skills, this route offers a practical and scenic option to add to your list.
