The Best Outdoor and Indoor Places to Go Rock Climbing in Northern Colorado

Because it’s so accessible in the region, rock climbing is one of those sports most Northern Colorado residents have tried at least once — whether inside or out. Multiple gyms, natural locations and local resources make it easy to pick up as a hobby.

Just minutes from Fort Collins, the most well-known spots for outdoor climbing and bouldering are located in Poudre Canyon, on Arthur’s Rock in Lory State Park, and around Horsetooth Reservoir. Offering both bouldering, rock climbing and sport climbing, there’s something for everyone and every skill level.

If you’re looking for expert tips, we recommend checking out Northern Colorado Climbers Coalition. This local organization serves to promote and preserve climbing in Northern Colorado. As the climbing experts in the region, they’re the best local resource to find guides, education, safety tips and more. They publish in-depth guides to specific climbing destinations, host regular public service projects in those areas, and offer a variety of community-building educational programs.

Horsetooth Reservoir | Fort Collins

John Gill, the Father of Modern Bouldering, is known as the man who popularized the sport —  and it all started right in Horsetooth Reservoir! The most popular place, with routes for everyone from beginner to expert, is Rotary Park. Overlooking the water on the east side of the reservoir, you can climb about 15 routes, including the popular Bolt Wall and the challenging Pinch Overhang. Other spots within Horsetooth include Duncan’s Ridge and the Torture Chamber which offer a few top roping options as well.

Poudre Canyon | Fort Collins  

Poudre Canyon is a mecca for climbers and boulderers of all skill levels. For the experts, it’s home to Circadian Rhythm V13 which is the hardest bouldering problem in the region. Overall, the canyon offers an even split of sport climbing and bouldering with a small slice of traditional and very little top rope.

NCCC offers a Poudre Canyon Route Climbing Guide, a Poudre Canyon Bouldering Guide, and a Poudre Falls Climbing Guide which focuses on the Poudre Falls area of Poudre Canyon.


Lory State Park | Fort Collins

One of the most well-known places for bouldering in all of NoCo, Arthur’s Rock is located just minutes from downtown Fort Collins. Mostly a granite conglomerate of several rock types, it offers more than 100 problems for boulderers of all skill levels. Development of the area began around 2000, but most recently, NCCC worked together with Lory State Park on the Arthur’s Rock Fixed Anchor Initiative which replaced old fixed anchors and established new routes.

See the updated guide from NCCC here.


Carter Lake | Loveland

Carter Lake Reservoir, located just west of Loveland and Berthoud, is another hotspot for bouldering. With around 20 routes total, you’ll find challenges that rank from intermediate all the way up to expert. One of the most classic and beloved routes in the area is Kahuna Roof, an intermediate V5 located on the steepest overhanging side of the Kahuna boulder.

Grazing Allotment Crag | Red Feather Lakes

The most classic climbing destination in the Red Feather Lakes area is the pristine Grazing Allotment Crag. NCCC even calls it the best crag in all of Red Feather Lakes. Offering both traditional and sport climbing routes, it was most recently developed in 2012 which created more lines and a better, more varied grade range.

Big Thompson Canyon | Estes Park

Nestled between Loveland and Estes Park, Big Thompson Canyon offers a bit of every style of climbing — even two aid climbing routes — but is mostly a destination for traditional and sport across gorgeous granite and gneiss crags. However, with over 400 routes total and various types of rock, everyone can find a challenge in the area.
