Boulder Rock Climbing

Home to more than 5,300 climbing routes — arguably one of the highest concentrations of rock climbs in America — Boulder’s variety of terrain, sunny weather and avid climbing community make it a world-class rock climbing town. In fact, the first recorded rock climb in Colorado happened in Boulder in 1906 when the now-famous Third Flatiron was ascended.

"Many people — not just locals — argue that Boulder, together with nearby Rocky Mountain National Park, is the single most desirable all-around rock climbing destination in the United States, and certainly one that rivals the most sought-after international rock destinations." — Alpine Institute

Climbing Areas

With so many options to choose from, here is a list of Boulder’s most iconic and best climbing areas in and around town.

The Flatirons

Arriving in Boulder, only the stillest of hearts are not moved by the iconic, tilting, red-rock formations seen on the city's horizon. Records show these sandstone beauties were climbed even at the beginning of the 20th century, but it's likely that Indigenous tribes have been climbing the striking slabs for centuries.

The Flatirons offer a type of climbing for everyone: legendary sport climb lines like Chains of Love (5.12b) (the only rock climb ever featured on the cover of TIME Magazine), stunning boulder problems such as The Turning Point (V8), and the classically exposed and often scrambled trad routes found along the east faces of any given Flatiron formation. 

Explore the heartbeat of the city amongst these sandstone blocks and see why thousands of people flock here every year to stand on their summits.

Eldorado Canyon

As one of the most famous climbing destinations in the country, Eldorado Canyon State Park is the mecca for trad climbing in Colorado. Trad climbing, or traditional climbing, is when temporary climbing gear is placed in the rock by the climber, not permanently bolted as in sport climbs, keeping walls free of gear and allowing more creativity in how to reach the summit. And while there may be more than a thousand trad climbs in “Eldo," as the locals call it, there are still a number of amazing sport climbs and boulder problems to explore as well.

Redgarden Wall, the largest cliff in the park and hard to miss for that reason, lies on the north side of the park just across from The Bastille. Both of these areas offer some of the most classic climbs in Colorado, like The Naked Edge (5.11b) and The Bastille Crack (5.7) — cornerstone test pieces of rock climbing in America. 

Eldorado Canyon is a very popular state park (pass purchase required) and has limited parking. On summer weekends and holidays, timed-entry reservations are required. Or utilize the Eldo Shuttle, a free summer weekend shuttle to get to the park. Have fun and gear up for an unforgettable day of climbing red conglomerate sandstone!

Trash the Trash

Pack it in, pack it out: Take everything with you, and yes we mean everything. Wag bags can be found and are regularly restocked at various climbing areas in Boulder to help mitigate waste at popular crags. No wag bag? Cat holes are acceptable for waste management, just be sure to bury your business six to eight inches below the surface.

Flagstaff Mountain

With more than 400 boulder problems, Flagstaff is the local bouldering area for most of the Front Range. Perched just minutes above downtown with horizon-reaching views, shady trees, an abundance of wildlife and more climbs than you can throw a crash pad at, one can spend an entire afternoon jumping from boulder to boulder testing strength and power.

Many Boulderites have adopted the “work hard, play hard” lifestyle and can be seen running laps on The Monkey Traverse (V4) after office hours. Don’t be fooled by the grades here, though! Flagstaff is notoriously "sandbagged," meaning the grades give the appearance of being easier than they are, and the rock quality is sharp so be ready for your fingers to feel it!

Other classic climbs in the area are First Overhang (V6), The Pillar (V2), Hollow’s Way (V8+), and Trice (V12). Be sure to bring crash pads and don’t forget a permit to park if your car is not registered in Boulder County.

Boulder Canyon

More than 1,800 climbs can be found in Boulder Canyon, and they range from easy trad multi-pitches to one of the hardest bouldering problems in the nation, The Game (V15). Apart from the variety and diversity of climbs, Boulder Canyon is also unique in that the canyon is mostly granite. Most of Boulder and the Front Range consist of sandstone or gneiss rock. Granite, a much hardier and “bulletproof” rock, is less likely to break and gives climbers ease of mind when ascending a wall.

Explore stunning vistas of the Arapahoe Peaks from the top of the classic multi-pitch Bitty Buttress (5.8+), or test your grit on the sporty arete climb Lucid Dreaming (5.12d), perched oh-so scenically above the iconic Boulder Falls

Perhaps ropes aren’t your thing? The Citadel (V8) is the perfect boulder for escaping the heat during Boulder’s warmer months and has a collection of three climbs of varying difficulty for all climbers in the group. Whatever it is you climb, Boulder Canyon has something to offer.

Know Before You Go

Seasonal closures in Boulder Canyon to protect raptor nesting are common. Please check for updates on the Boulder Climbing Community's website before you head out.

Upper Dream Canyon

Technically a part of Boulder Canyon, Upper Dream Canyon rests high above Boulder Falls and offers some of the best rock climbing in the country. Made of the same tough granite as the rest of the canyon, this is more easily accessed from above than below. Boulder Climbing Community has done a lot of work over the years to help establish a trail with better signage for all climbers to navigate. 

While the Canyon offers mostly sport climbs with classics like Divination (5.11b) and Archangel (5.12c), bouldering problems can be found here, too. More notably, iconic trad climbs like China Doll (5.14a), one of the hardest trad climbs in Colorado and steeped in history, beautifully streaks across the Lost Angel Wall, tempting amateurs and pros alike.

When venturing to Upper Dream be sure to respect private property and pack out whatever you pack in to keep this beautifully remote area better than you found it.

Climber Resources

Being the rock climbing destination it is, Boulder has a plethora of resources for climbers both on and off the wall. Stock up on gear or sit in on a pro climber talk at the legendary mountaineering shop, Neptune Mountaineering. Resole your old pair of climbing shoes at the local’s favorite cobbler, Rock and Resole. Enjoy a post-send beer and slice at Backcountry Pizza & Tap House or stretch out and rejuvenate your muscles with a yoga session at one of Boulder’s many yoga studios.

Climbing Guides, Tours and Gyms

New to climbing or want a local’s perspective? Going with a climbing guide can get you off the ground and onto a rock wall faster than you thought possible. Boulder's an international climbing mecca, and a wealth of climbing experts live and work here, making this the perfect place to learn how to rock climb. Look to pros listed below to get started or improve your rock climbing skills.

Searching for an indoor climbing wall? Boulder is home to world-class gyms where many pro athletes regularly train and compete. They’re also a great resource for finding belay partners, locals with the inside scoop and a nice place to shower and relax after trying hard.
