While Fort Collins' locals have been climbing at Arthur’s Rock for decades, the main development phase of bouldering began in 1999, led by Pat Goodman. Since then, Arthur’s Rock has remained a cherished and hidden gem frequented by locals but largely unknown to the larger climbing community.

This is a great area for Winter, Spring, and Fall. Conditions can be excellent here in the coldest of winter months due to the sunny, south-facing aspect of the hillside and cliff. There are rattlesnakes in the summer, and it is generally too hot to climb here. Arthur's Rock is most known for its bouldering, but it also has a small collection of trad and sport routes.

The rock quality at Arthur’s Rock has been described as being anywhere from total choss to a granite technician's dream. Mostly a granite conglomerate of several rock types, the climbing tends to be fingery and requires very technical footwork. Small edges, gritty slopers, and the occasional pink knob are the norm for grips around Arthur’s Rock.

Check out the comprehensive, online, free to print, guidebook by NC3 here here. The printed version of the Lory State Park Guidebook is now available at the Lory State Park Visitors Center, Jax Outdoor Gear, and Miramont Fitness North.

The NCCC has worked with Lory State Park to establish the Arthur's Rock Fixed Anchor Initiative. Replacement of old fixed anchors and establishment of new routes that require fixed anchors is now possible through an application process. Please consult the Lory State Park Guidebook for more information.

Getting There

From downtown Fort Collins, head west on Laporte Ave. until it ends. Turn right on Overland Trail and head north for approximately 2.5 miles. Turn left on Bingham Hill Rd/Co Rd 50E, and go west for 2.0 miles. Turn left onto N Co Rd 23 for 1.2 miles and finally a right onto N Co Rd 25 G. Take 25G for 1.6 miles until you reach the gate for the park. There are signs for Lory State Park after the Bingham Hill turn off Overland Trail.

From the Park entrance, proceed to the Visitor's Center to pay for your day or annual pass. From there, continue down the main road (Lodgepole Dr.) until it dead ends at the parking lot for the Arthur’s Rock Trail.

Does anyone know what route this is? We saw it when we were climbing 125. There's 4 bolts and a 2-chain anchor, so figured there's gotta be some beta on it somewhere?

Any trad routes at Arthur's? Apr 10, 2010
I added this area in hopes of something bigger and better arising. I don't know enough about the area other than a few problems. It's worth the visit. Please help add problems and pictures if you know the area. Feb 21, 2009
