Which way are you going?
While Fort Collins' locals have been climbing at Arthurís Rock for decades, the main development phase of bouldering began in 1999, led by Pat Goodman. Since then, Arthurís 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 Arthurís 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 Arthurís Rock.

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.

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.
