Arthur's Rock is a rock Climbing destination inside Lory State park just a short hike away from the parking lot and Arthur's Rock trailhead.

This is a great climbing area for Winter, Spring, and Fall. Conditions can be real fun in the coldest of winter months due to the sunny, south-facing aspect of the hillside and cliff.

Need to know: An entrance fee is required to enter Lory State Park.

Arthur's Rock is most known for its bouldering, but it also has a small collection of trad and sport routes.

Rock quality at Arthur’s Rock has been described as being anywhere from total choss to a granite technicians dream. Mostly a granite conglomerate of several rock types, the bouldering 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.

On the linked website, there is a climbing guide from Northern Colorado Climbing Coalition if you want more info.
