Lime Line on Redgarden Wall at Eldorado Canyon presents a gritty, straightforward trad climb that demands a practical approach amid a rugged setting. Stretching 80 feet, this single-pitch line follows a series of cracks and grooves that offer intermittent bursts of engaging moves. The route carries a modest 5.8- rating, making it approachable for climbers with some experience, yet its uneven condition and scattered lichen patches temper the overall appeal. The rock wears a rough character underfoot and hand, with protection opportunities generally solid but occasionally requiring careful placement of cams from 0.4" to 3". Climbers will find a fixed sling at the second tree about two-thirds of the way up, a crucial anchor for descent or belaying.

Accessing Lime Line involves a deliberate approach through Redgarden, where the walls rise sharply against the open sky, offering intermittent views of Boulder’s rugged landscape. The surrounding terrain is steep and rocky, demanding sturdy footwear and focused attention when moving in to the base. The descent can be handled by deploying a rappel from the sling anchored to the established tree or by lowering your partner down onto the adjacent ramp, which can be downclimbed cautiously. This part requires steady footing to avoid loose rock or tricky spots.

While the climb’s overall rating and star count reflect its less-frequented status, Lime Line rewards careful climbers with moments of genuine crack climbing and groove negotiation. It's an ideal choice for those who don’t mind a bit of lichen and rough rock in exchange for an authentic Redgarden Wall experience. Especially in drier months, the line presents a solid adventure with minimal approach fuss or complicated logistics.

Gear-wise, a full rack with a focus on cams from 0.4" to 3" is essential. Protection placements are not widely spaced but require some mindfulness due to the uneven texture of the rock and occasional vegetation. Since the route isn't heavily trafficked, checking for loose rock and cleaning holds or gear placements beforehand helps ensure your safety and enjoyment.

Lime Line’s position in Eldorado Canyon State Park places you in one of Colorado’s classic climbing areas, known for steep sandstone formations and a demanding climbing environment. While this particular climb isn’t among the most polished or heavily traveled, its rawness appeals to those wanting a no-frills traditional climb with manageable technical challenges. Taking on Lime Line encourages you to engage directly with the rock and the setting, acknowledging the occasional rough edge as part of the adventure.

Prepare for this climb by timing your ascent to avoid mid-day heat, especially in summer, since the rock absorbs sun and offers limited shade on this wall. Early morning or late afternoon sessions provide cooler conditions and better friction. Hydration, appropriate footwear, and a clear plan for descent are crucial to a smooth experience here. Though it lacks the flashy allure many seek in Eldorado Canyon, Lime Line serves as a practical test of trad skills and route management in a quietly compelling stretch of Colorado climbing terrain.
