Over the years, I’ve ditched climbing Colorado’s famed 14,000 foot peaks in favor of a more rugged feel. Colorado 13ers are where it’s at if you desire a hiking and scrambling challenge, thin air, and few crowds. Here’s a look at a few of the best Colorado 13ers near Denver.
Although these mountains don’t have the same clout that the famed Colorado fourteeners have, they lack the line of hikers found on their 14,000-foot cousins. Colorado’s 13,000-foot peaks require a lot more route finding and off-trail travel, making them have more of a real mountaineering feel.

What is a Colorado 13er?
A Colorado 13er refers to a peak that sits over 13,000 feet above sea level. Even though these peaks are shorter and more numerous (there are over 600 in Colorado alone), they are still just as challenging, if not more challenging than a Colorado 14er.
Expect to have the same amount of elevation gain as a Colorado 14er, but far more of a challenge. With so many amazing Colorado 13ers to choose from, it can be tough to choose the best Colorado 13er.
Why Climb a Colorado 13er Instead of a 14er?
Colorado 14ers became more of a novelty than a quiet mountain hike. Even the tougher 14ers have crowds of people flocking to climb them. Not to mention, all 14ers have a trail and an app you can use to get a step-by-step guide on how to climb them. I don’t know about you, but that’s almost cheating in my book.
Colorado 13ers offer more of a challenge since there often isn’t a trail to the top, information or beta is limited, requiring you to harness your awesome mountain skills to reach the top.
One of my favorite parts of climbing any Colorado thirteener is the solitude. Often times, you’ll be the only one on the summit of these magnificent peaks. In certain areas, like the easily-accessible Tenmile range, you can have the peak to yourself and wave to the endless sea of people on the tops of nearby 14ers.
If you like solitude and bit more of a challenge, the best mountains to climb in Colorado are the 13,000-foot peaks.
How to Find Awesome Mountains to Climb Near Denver
Finding these awesome peaks of solitude actually isn’t all that difficult. Often times a well-known Colorado hiking trail terminates at the base of the thirteener. Your next step is to carefully choose your way to the top!

1. The Sunset Jaunt: Mount Sniktau (13,240 feet)
Whenever someone mentions a great beginner 13er peak, Sniktau always makes it on the list. Located along the Loveland Pass ridgeline, this mountain provides easy access with zero approach. The total round-trip length is only 3.7 miles, making it an ideal starter for anyone who is new to climbing mountains and a little hesitant to start on something more substantial.
If you’re a seasoned vet, this mountain makes for a great perch to watch the setting sun and is one of the best hikes near Denver. Expansive views of the Continental Divide, Eagle’s Nest Wilderness, and Holy Cross Wilderness can’t be beaten. On a clear day, you can see all the way to Long’s Peak to the north.
- Class: 1
- Round-trip distance: 3.7 miles
- Elevation Gain: 1,800 feet
- Required gear: Hiking gear with a few extra layers
- Best for: New climbers, quick summits, sunsets

2. The Gentle Hill Walk: Mount Parnassus (13,579′)
Mount Parnassus was not a fun climb for me personally, but if you’re into hillwalking, this is a great peak. Despite my lack of hillwalking lust, the views from the top are beautiful. Neighboring Bard Peak adds to the drama, the ridgeline presents itself as a fine challenge. If you’re looking for a bigger challenge, then consider adding Bard to the loop. I did this peak in the winter and it’s a lung buster if there is no trail in the snowpack.
- class: 1-2
- Distance: 8 miles without Bard, 9 with
- Elevation gain: 3,334 feet
- Gear: Summer – regular hiking gear with extra layers. Winter: Snowshoes and microspikes (for the approach)
3. The Best Beginner Winter Ascent: West Ridge of Atlantic Peak (13,841 feet)
Why not climb mountains year-round? Winter may be a tougher season, but that doesn’t mean that you still can’t climb mountains! If you have the correct gear and avalanche training, try for a winter peak. Atlantic Peak in the Tenmile Range is a great beginner winter mountaineering route in Colorado. The Atlantic Peak’s West Ridge has a minimal approach of approximately three miles and plenty of ridge to enjoy. The views of the dramatic ridge between Atlantic and Fletcher make you feel like you’re far off in the Himalaya.
- Class: 2
- Round-trip distance: 4 miles plus 2.8 miles of road walking (if the road is closed, which in winter, it is).
- Elevation gain: 2,450 feet
- Required gear: summer – standard hiking gear with a few extra layers. Winter: ice ax, microspikes/crampons (depending on snow), snowshoes and avalanche safety gear.

4. Best All-Round Climb: The Citadel to Pettingell Traverse
Hands-down one of the best all-around climbs and one of my favorite Colorado 13ers. This climb, best done in conjunction with Snoopy’s Backside Couloir offers a bit of everything. The approach is on the longer side, but with twin summits, The Citadel (13,294′) provides some fantastically spicy scrambles on its own. Combined with Pettingell, the route turns into a Class 5 traverse with lots of exposure to keep the heart pumping. The Citadel is one of the best mountains to climb in Colorado, and nobody has ever heard of it. A true gem!
The crux of the climb is a 55-foot rappel off of a vertical rock face. You can opt to continue on to Pettingell through some more Class 3 scrambling and a Class 2 walk-off or descend the steep saddle after the rappel.
- Class: 3-4 rock with plenty of exposure and a Class 5 rappel
- Round-trip distance: 9.7 miles
- Elevation gain: 3,532 feet
- Required Gear: Summer – helmet for the Citadel and a 40m rope with an anchoring system, belay device, third hand and harness for the rappel. Winter: not recommended due to avalanche danger. However, for snow climbing season you will need all of the above plus crampons and an ice ax. Snowshoes are advised depending on snowpack
5. Climb Steep Snow in the Skywalker Couloir of South Arapaho Peak (13,400 feet)
If steep snow is what you seek, you can’t go wrong with the Skywalker Couloir route up South Arapaho Peak. This iconic Colorado snow climb makes its way up the southeastern face of South Arapaho Peak. This is no beginner snow romp, with angles upwards of 65-plus degrees, you’ll want an axe and a tool. Most of this half-mile long couloir is steep and above 45 degrees. Choose between three exits: the easy out, the steep Princess Leia alpine ice exit, or the class 4 scramble (gear recommended for some) Han Solo exit.
- Class: Class 2 walk-off of South Arapaho. Descend the standard route.
- Round-trip distance: 5.97 miles
- Elevation gain: 3,263 feet, with most of the gain in the couloir.
- Required Gear: This climb is best done in early to mid-June depending on the snow year. You’ll certainly want a helmet, mountaineering boots, crampons, an ax and one tool. Depending on conditions, newer climbers may want an ice screw or pickets and some rope for the top of Leia. Han Solo enthusiasts might want to bring a few pieces of trad gear and a rope for added protection (class IV terrain in mountaineering boots can be an experience). Remember, if you’re bringing ropes, you’ll need a harness and belay device with an HMS carabiner.
6. Scrambler’s Paradise: West Ridge of Pacific Peak (13,957 feet)
If you’re looking for some bang for your approach buck, look no further than the West Ridge of Pacific Peak. Pacific Peak’s prominent summit is screaming to be climbed. Approach via Mayflower Gulch for only a mile or so of travel along a faint climber’s trail. You’ll meet the ridge abruptly where you are greeted immediately with over a mile of Class 3 terrain. The rock is rotten in spots, but you can avoid some of it if you opt for Class 4 gullies. The summit is often a quiet place, where you can catch a view of nearby Quandary, a popular Colorado 14er. Wave to the crowds of people on the summit while you have Pacific all to yourself.
- Class: 3
- Round-trip distance: 4.0 miles if your vehicle can make it to the mine, 6.8 if you park in the paved lot.
- Elevation gain: 2,600 feet
- Required gear: Helmet
7. The Third Class Introduction: Father Dyer’s East Ridge (13,615′)
Whenever I hear that someone wants to get into Class 3 scrambles but has some hesitation, I recommend Father Dyer’s East Ridge. Once upon a time, I had a crippling fear of heights and exposure would send me into a full-on panic attack. When I finally mustered up the courage to try some Class 3 terrain, a friend of mine recommended Father Dyer Peak. The ridge allows you to scramble without the intense exposure. The route can easily be downclimbed, but if you aren’t up for it, you can climb the Class 2 Cyrstal Peak next door.
- Class: 3
- Round trip distance: 6 miles
- Elevation gain: 2,700 feet
- Gear: Regular hiking gear with a helmet. There’s no rock fall potential on this route, but I always feel better scrambling knowing that my noggin is protected.
8. The Arapaho Traverse
So nice it’s in here twice! After summiting countless mountains, one of my all-time favorites is the Arapaho Traverse in Indian Peaks Wilderness. During the summer months, you can scramble from the summit of South Arapaho Peak to North Arapaho Peak. South Arapaho is a class 2 walk-up (a great peak in its own right) and to tag the sister peak, you’ll scramble over the ridge on excellent rock until you reach the larger, North Arapaho summit. Come back the way you came.
The route is fairly obvious, with several areas where you can choose to scramble low fifth-class rock or walk around. For an extra-burly day, hit up the traverse after you take the Skywalker Couloir.
- Class: 3/4
- Round-trip distance: 8.3 miles round-trip
- Elevation gain: 3,500 feet
- Required gear: Helmet
Bonus: Mount Arkansas
If you’re looking for a serious winter challenge, or a fun-filled day scrambling in the alpine, then Mount Arkansas is for you. At 13,795 feet, Arkansas is a great way to catch some air without hiking long miles. You can avoid some of the towers if you aren’t up for scrambling, but what’s the fun in that?
In winter, Arkansas becomes a burly objective, especially since you’ll be forced to navigate cornices, blowing wind, and scramble over icy rock. It’s a worthy winter objective loaded with stunning views!
- Class: 3
- Round-trip distance: 5.25 miles round-trip
- Elevation gain: 2,750 feet
- Required gear: Helmet. Ice axe, microspikes, snowshoes and helmet in winter.
Preparing for Climbing or Hiking a Colorado 13er
Preparation for climbing the best Colorado 13er, or any mountain in Colorado for that matter, requires a few key important preparation points:
- Check the weather using a reliable source like Weather.gov. Then check it again, and again, up until the night before (or the morning of) your climb.
- Start before the sun rises. This is true in both winter and summer. In summer, you’re trying to beat the onslaught of inevitable thunderstorms that can put you in great danger. In winter, the snow gets warm and the avalanche danger increases as the day warms up.
- Pack the essentials and then some. Don’t forget warm layers, even gloves and a hat. Mountain ridges get cold. Check out this complete mountain climbing and hiking packing list.
- Print out maps and study your route. Try and look up recent conditions, ask forums if any special gear is needed, and get a clear sense of what you are getting into.
