Nestled in one of the best states for rock climbing, Colorado’s “Front Range,” the north-to-south stretch of granitic and sedimentary foothills and mountains, gives climbers thousands of routes to climb. From the bulletproof sandstone of world-famous “Eldo,” to the towering alpine routes of Rocky Mountain National Park, one of the best places to rock climb in the world offers too many routes to do in a lifetime – and they’re all within 90 minutes of Boulder. Dirtbagging can be a challenge, but there are camping and van-bivying options here and there. Short-term rentals abound in Denver and Boulder, too, so whatever your travel budget you can make some quality climbing happen on the Front Range.
1. Eldorado Canyon State Park
Infamous, intimidating, and overall awesome, “Eldo” demands a full toolbox of skills from climbers. Fixed anchors exist, but not everywhere. Some of the rock is bulletproof, while small sections are loose and unpredictable. Some locals swear by specialist gear like RP’s and Tricams, but everyone agrees a cool head and steady technique help keep the stress levels under control.
Once the home to Mountain Utes and then a marquee luxury resort where Dwight and Mimi Eisenhower honeymooned, Eldo today is a world-class destination for traditional climbing. Even the moderates can be surprisingly spicy, so heads up when tying in…even for an “easy” climb!
Steve Levin’s excellent guidebook Eldorado Canyon, is a must-have for its accurate information and crisp color photography, but also for its authoritative history of the canyon. Expect phenomenal climbing interspersed with shattered ledges, unobvious route-finding, and antique, fixed gear.
Hiring a guide for a day can help you get a sense of the area and strategies for managing the complexities or consider joining one of the many rock climbing camps to build out your technical skillset alongside other stoked folk. Whatever your psych level, Eldo delivers a rewarding day of climbing, hard won on the towering cliffs.
Having survived the eras of piton smashing and mad bolt drilling, Eldo is truly a place of adventure where a comprehensive skill-set is demanded to negotiate often tricky descents, acrobatic sequences and sustained movement.
Eldorado Canyon State Park - Good to Know
Advanced. Better destination for more experienced climbers, or hire a guide
Summer can be hot; early start recommended
Plenty of west-facing climbing; mornings are awesome! Afternoon winter climbing is also a great option
The chipmunks are notoriously enterprising. Hang packs at the base of routes or at least remove all food from them!

It’s tricky, but Golden Gate Canyon State Park and the RV Park downtown Golden can work; check out Boulder Canyon Adventure Lodge for tent sites, too
Neptune Mountaineering is minutes away, in south Boulder
Just beside and below Neptune are great options: Southern Sun brews its own beer and Tandoori
Grill is some of the best Indian on the Front Range
2. Lumpy Ridge, Estes Park
Technically part of Rocky Mountain National Park, Lumpy Ridge is less alpine rock than fantastic multipitch cragging. Compact granite, distinguished by flaring cracks, gives Lumpy its own feel on the Front Range. Relatively few bolts and mostly multi-pitch routes, Lumpy requires a competent climber to get on its longer, bigger routes. The rewards, though, are many: great climbing, an epic view of Longs Peak to the south, and moderate classics in the mountains.
Lumpy Ridge is one of the most scenic and beautiful rock climbing areas in North America. The climbing is a mix of styles that are a blend of Yosemite-style cracks and slabs with Joshua Tree-textured granite.

Bernard Gillett’s Rocky Mountain National Park: Estes Park Valley: The Climber’s Guide has great topos and accurate info
Reliable cell coverage (keep an eye on the radar; lightning can be deadly up there!)
Early starts required for the classics on weekends
Moderately priced hotels down in town and camping in the national park; reserve early in high season
Bring plenty of water, there’s south-facing rock and dry Colorado air
The Mountain Shop in Estes has a modest climbing/bouldering gym, as well as a good gear selection.
None for Rocky (cool!)
Ed’s Cantina is where it’s at for climbers
3. Rocky Mountain National Park
“Rocky” is home to 4000m peaks, one of the highest paved roads in North America (Trail Ridge Road, one of the coolest spots for mountain biking in Colorado), and some of the best alpine rock anywhere. It is also home to some of the best hikes you can find in Colorado, from easy to advanced.
While the true alpine terrain requires self-sufficient climbers, don’t be too intimidated: there are tons of moderate routes here, starting at lower fifth-class. The rock is generally good, but it is alpine: inclement weather, rock- and icefall, altitude, and tricky descents are all part of the game.

Solid intermediate and advanced climbers will get the most here

Popular routes can be crowded; early starts are mandatory and hit the backcountry desk early to get bivy permits.
Afternoon thunderstorms are certain; start early and know how to retreat efficiently
A Day Pass for Rocky is $25; Seven Day Vehicle Pass is $35; annual pass $70.
No park pass required at the Longs Peak Trailhead
4. The Flatirons
Staring down at the college town of Boulder, the slabby, picturesque Flatirons mark the spot where the Rockies push up from the Great Plains. The east faces are all relatively mellow with routes as forgiving as 5.3. Young kids, first-time climbers, and everyone in between routinely climb the featured sandstone lines.
Widely spaced protection stresses out newer leaders, but if they can stomach the sparse gear options, the summits look towards Rocky Mountain National Park to the north, the Indian Peaks to the west, and across the endless plains to the east. The steeper west faces, many of them overhanging, hide bunches of sport routes and morning shade, too. It’s an awesome venue with great hiking, trial running, bolt clipping, and long moderates.
The Flatirons feature some of the best beginner multi-pitch climbing in the US, as well as old-school climbs like The Northwest Passage and The Maiden’s splendid North Face.

The popular moderates are generally east facing, start early in summer or at least wait for the sun to pass by the summits and climb in the shade
Sunset on top of the 1st, 2nd, and 3rd Flatirons is must
Larger gear can help with finding belays, a number 3 for sure and maybe even a Hex (woh!) will help with building anchors

5. South Platte
The Platte! Huge granite domes, part of an enormous batholith, jut into the sky just west of Denver. This is Joshua-Tree style granite climbing on friction-y crystals in the tan rock.
There are granite splitters here, as well as multipitch slab routes, all detailed in Jason Haas’s new guidebooks, South Platte Climbing. Note that because the formations are extensive enough and spaced enough, Haas wrote both a northern and southern volume of the book. This gives you an idea of the depth and quality of the climbing – awesome!
South Platte is always putting the traditional backcountry rock climber to the test!

There are a few super-quality beginner routes like Classic Dihedral, but mainly 5.9 and harder terrain
Plan on driving between crags, often on dirt. Some crags are spaced by miles.
Heads up during thunderstorm season!

South-facing routes can be surprisingly warm in winter, and hot in summer. Choose your aspect carefully
Some formations, like Cynical Pinnacle, are closed for raptor nesting. Check before you go

Some bolted routes are still widely spaced; the Platte is not overbolted!
6. Clear Creek
Tumbling from the mountains into the college town of Golden, Clear Creek cuts a deep canyon through granite, schist, and gneiss. Well bolted and with climbs ranging from 5.5 to 5.13, Clear Creek offers a dizzying array of most sport climbs – but the occasional trad route, too. South-facing routes climb all winter and the dozens of routes help keep crowded days manageable. Clear Creek is an awesome venue for every level of climb, practically year round, too.
Sport climbing destination with routes and terrain that would suit almost whatever bolt-clipping desires you may have; as well as quick and fun roadside ice to stay busy in winter.
