Set against the raw granite faces of Nightmare Rock within the renowned Murrin Park, "Who's Your Daddy?" offers climbers a sharp introduction to technical trad climbing in Squamish. This single-pitch route, occupying the left side of the imposing Grandaddy Overhang, challenges you with a play of precision and bold movement: the obvious crack draws you upward, coaxing confident hand and footwork as you navigate subtle holds. After committing to the initial crack, the line veers right where the rock opens, demanding both mental focus and fluid technique to bypass a bolt and reach the anchor established at the Grandaddy Overhang’s lip.

With a length of 45 feet and rated at 5.10d, this climb strikes a critical balance between accessible warmup and meaningful challenge. The rock quality is classic Squamish granite—solid and textured, offering reliable friction yet requiring clean foot placements. Gear placements are straightforward but expect to workspace traditional protection up to three inches, making a rack packed with cams essential for a confident ascent.

The approach to Nightmare Rock is both swift and scenic. Parkings near Murrin Park lead you through a brief but well-marked trail, winding past towering firs and mossy boulders. The terrain here is typical coastal British Columbia—slightly damp, often cool, with a freshness in the air that sharpens focus. Timing your climb early in the day ensures shaded rock, minimizing heat while the cliff wakes with the morning light. Late afternoon sessions can get warmer but expect shadow from the overhang to provide partial relief.

This route is a practical choice for climbers wanting to warm up before tackling more extended lines around Murrin. Its moderate length and clear protection opportunities allow for refining crack climbing skills without committing to a multi-pitch adventure. The setting itself is alive with energy—the forest around whispers with the wind, and occasional birds punctuate the rhythm of your moves.

Planning your ascent means packing essentials like gloves for crack protection, a rack emphasizing medium to large cams, and sticky rubber shoes to tame the friction. Hydration is key; a water source is nearby, but carrying enough for the day is necessary, especially in summer. Check weather forecasts before heading out since wet granite quickly turns treacherous. As with any Squamish route, leave no trace to preserve the natural state of this climbing haven.

"Who's Your Daddy?" invites a connection with the rock—each hold and crack feels almost alive, responding as you test your strength and technique. It’s not just a route but a measured dialogue between climber and cliff, perfect for those sharpening their edge in British Columbia’s climbing heartland.
