Left Hand Rock’s Left Dihedral stands as a tangible link to climbing’s bold past, offering a straightforward yet compelling trad climb that gently tests your technique and nerve. Located in the Jurassic Park area near Lily Lake, this single-pitch route invites climbers to engage with rock that’s been touched by hands seasoned in decades of ascent.

The climb presents a left-facing dihedral that demands thoughtful footwork and clean hand placements. The defining feature is the transition near the top—a daring move left around a noticeable bulge that pushes into a hand-sized crack leading to the summit. This crux elevates the climb's intensity, requiring precise control and commitment. While the grade of 5.9 might seem approachable, the unique sequence adds a punch of challenge that seasoned climbers will appreciate.

Set against the backdrop of the Estes Park Valley, the rock is solid but demands attention. Protection calls for a well-rounded rack focused on standard sizes with an emphasis on hands-size gear and larger pieces to secure the tricky sections. The route’s historic ascent, dating back to June 1972, gives it an aura of quiet reverence among local climbers.

The approach to Left Hand Rock is moderate, accessible from established trails near Hwy 7 & tributaries. You’ll find yourself moving through forested areas that guard the path before arriving at Jurassic Park’s distinctive rock formations. Arrive early in the day to catch the wall in ideal lighting—morning sun warms the face, while afternoons bring cooling shade. The area's elevation hovers just over 7,000 feet, making hydration and sun protection a key part of your preparation.

Descent is straightforward with a walk-off option, but careful footing is advised on the rocky terrain to avoid any slips after your climb. The route’s single pitch means you can plan a quick, focused outing or incorporate it as a warm-up to more extensive climbs nearby. Whether you’re revisiting a classic or testing hands-size placements, Left Dihedral offers a slice of Colorado climbing history combined with the practical demands of trad protection.
