Purgatorius stands as a striking test of commitment and finesse on the rugged vertical face of The Little Fin in the Jurassic Park sector, within the Estes Park Valley. This single-pitch, 60-foot sport climb demands attention not only for its gritty, featured rock but for the mental edge it requires. Beginning on a micro-flatiron outcrop, the route eases you into the climb with a few straightforward moves past three bolts, drawing you steadily upward. After this initial stretch, you'll find yourself reaching long to clip the next bolt—this sets the tone for what’s to come.

The middle portion of Purgatorius is where the dance begins: a cruxy move around the fourth bolt that veers right, then up, before shifting left. The terrain here is exposed enough to keep your focus sharp, with edges and flakes that ask for trust in both body and gear. The protection, spaced with seven bolts total, provides security, but spacing near bolts four through six increases the consequence of any missteps. Notably, the sixth bolt hangs just over an edge, making falls particularly risky as your quickdraw dangles precariously—clipping a sling here might be wise but requires careful thought.

As the angle eases near the top, the route finishes at a two-bolt anchor perched on solid rock, a welcome reprieve after the technical crux zone. This climb feels like a blend of adventure and sport climbing — its route-finding elements and underway flow challenge even seasoned climbers to remain deliberate with each move.

The rock’s grit gives good friction, but it’s not without loose flakes in places, so clean-up after traffic will improve conditions and confidence. The name Purgatorius nods to an ancient creature that survived the dinosaur era — a fitting metaphor for a climb that demands resilience and respect.

Located near the highway, access to The Little Fin is straightforward, but the approach calls for caution on steep talus. Expect a brief hike across uneven terrain, requiring solid footwear and readiness for rocky footing.

When planning your ascent, bring gear suited for sport routes—draws for the bolts and a sling for tricky clipping spots—and prepare for the mental challenge of longer falls around bolt five. Early morning or late afternoon climbs offer the best shade on the wall, with afternoon sun warming the rock in cooler seasons. Hydrate well, wear supportive climbing shoes with good edging capability, and pack light to balance agility with safety.

Purgatorius is a climb that rewards focused energy and sharp beta, combining the thrill of exposed moves on gritty stone with the practical challenge of careful clipping and route reading. It’s a solid pick for climbers looking to test their sport skills on Colorado’s complex limestone faces, where adventure still speaks through the bolts.
