Dan's Line: A Crisp Sport Climb in Boulder Canyon

Dan's Line stands as a straightforward yet engaging sport climb within the Upper Tier of the Bihedral area, offering climbers a solid taste of Boulder Canyon's classic granite. This 100-foot route begins just left of Hold The Line at a low, comfortable boulder shaded by a small pine, setting the scene with a tranquility that contrasts Boulder’s usual buzzing energy. The start invites you to settle in before moving left onto a smooth ramp where the first bolt comes into view. From here, thin moves challenge your balance and footwork, requiring precise edging rather than brute strength.

As you ascend past the second bolt, the rock leans over slightly with an easy overhang daring you to maintain control rather than rush. The slab above demands focus; subtle edges and small crimps invite a careful cadence. Your hands connect with the rock’s texture, feeling the granite’s grain, while the forest scent lingers faintly on the breeze. The climb culminates at a well-built two-bolt anchor equipped with lowering hooks, positioned to offer a safe and straightforward descent.

Route spacing features eight bolts that maintain a confident but relaxed pace, making it an ideal climb for those honing sport climbing technique or seeking a reliable moderate pitch. The 5.8 rating is honest—accessible without being trivial—but expect moments where thin holds require finesse rather than power. With an approach easy enough to navigate and a manageable rope length of 60 meters for a clean lower-off, Dan’s Line blends practical accessibility with enjoyable climbing.

For those wanting to push further, a higher anchor 10 feet above allows a segue onto "Puff Daddy," rated a step harder at 5.10a, extending the experience upward for climbers seeking more challenge. The area itself, Boulder Canyon, holds broad views and crisp mountain air, reinforcing why the Front Range draws climbers year-round.

Gear-wise, the fixed bolts minimize the need for extra protection, focusing the effort on climbing rather than managing gear placements. The rock quality remains solid throughout, though staying alert to slab climbing nuances ensures a safer, more confident ascent. Early morning or late afternoon climbs are recommended to avoid strong sun and to enjoy cooler temperatures on the face. Watch the approach trail: it’s short but cuts across mixed terrain that can be slick after rain.

All told, Dan's Line is a practical, fulfilling route for intermediate sport climbers eager to experience classic Front Range granite without steep commitments. Whether you're building skills or simply savoring a crisp climb in a scenic canyon, this route delivers a direct connection to the landscape, balancing measured challenge with straightforward flow.

Climber Safety

While the bolts are solid and well spaced, the slab section can become slick when wet. Avoid climbing immediately after rain and check for any loose debris near the start. The anchor’s lowering setup is reliable, but always double-check gear and rope management to ensure a safe descent.

Route Rating

Difficulty
5.8
Quality
Consensus:Rated 5.8, Dan's Line is friendly enough for intermediate climbers but demands attention on the thinner, slabby sections. The grade feels true to its difficulty with no major soft spots; moves rely on balance and precision rather than raw power. Compared to other Front Range routes, it's a straightforward pitch with consistent protection and a manageable crux near the middle.

Gear Requirements

The route features eight well-placed bolts leading to a secure two-bolt anchor with lowering hooks. A 60-meter rope suffices for a clean lower-off. Extra gear is generally unnecessary given the reliable fixed protection.
