Rising from the rugged face of Main Crag in Big Thompson Canyon, Conundrum offers climbers a focused encounter with Colorado’s sharp granite. This single-pitch, 100-foot route commands respect with a 5.9 rating that challenges your technique without overwhelming with length. It begins with a determined move over a bulge that tests both strength and balance, immediately pulling you into the rock’s texture. From this crux, the climb eases into a chickenhead-laden slab—an inviting surface peppered with natural holds, each offering a tactile invitation to progress steadily upward. As you advance, the slab smooths beneath your hands and feet, but the presence of two well-placed bolts midway provides a reassuring rhythm to clip and rest if needed.

The route culminates at a pair of anchors perched on a ledge that commands sweeping views of the Estes Park Valley, rewarding climbers with open exposure and a clear line of sight to the canyon’s rugged silhouette. This climb keeps you intimately engaged with the rock, its textures ranging from rough bulges demanding precise footwork, to smoother slabs that encourage thoughtful placement and body positioning.

Accessing Conundrum is straightforward, with a solid approach through the Main Crag area’s defined trails. The crag’s orientation allows for morning light to warm the route, making spring and fall the optimal seasons to enjoy crisp conditions without the intense heat of summer.

Protection calls for a well-rounded rack: slings for the horns, nuts, and cams up to 2 inches will keep you secure on this traditionally protected line. The two bolts found higher on the pitch offer reliable clipping points, easing the mental load during the slab section. After reaching the anchors, a 30-meter rappel efficiently returns you to the base, avoiding any hazardous downclimbing or lengthy walks.

Though short, Conundrum is an excellent test-piece for versatile climbers seeking to sharpen their crack and slab skills in a clean, no-frills setting. Its approachable 5.9 grade is complimented by thoughtful placements and a crux that feels honest—not inflated or underwhelming. With four votes averaging moderate interest, this route remains a solid entry in the Big Thompson Canyon climbing experience, especially for those looking to combine technical climbing with scenic rewards.

Prepare for this climb by bringing comfortable shoes with excellent edging capabilities and a moderate rack including cams sized to fit the chickenheads and cracks. Keeping hydrated and timing your ascent to avoid afternoon heat will elevate the experience, allowing you to fully appreciate the steady rhythm of moves and the crisp Colorado air buzzing quietly through the canyon.
