Skip the brewery tour, climb a Flatiron.

Most visitors experience Colorado from a trail, a scenic drive, or a brewery patio. Only a few experience it from 1,000 feet up on one of Colorado's most iconic rock formations.

The Boulder Flatirons rise dramatically above the city, offering beginner-friendly multi-pitch climbs, incredible exposure, and panoramic views stretching from Boulder to the Continental Divide. Whether you're looking for your first real climbing adventure or a unique way to experience Colorado, climbing a Flatiron is a day you'll be talking about long after your vacation ends.

We provide the technical equipment, guide the route, and help you experience one of Colorado's classic adventures safely and confidently. Come experience the real Colorado.

Looking for more people to climb with this summer? Our Community Climb Nights are designed to bring Boulder (and surrounding areas) climbers together in a welcoming, low-pressure environment where everyone can learn, climb, and have fun.

Whether you're transitioning from the gym to outdoor climbing, searching for new climbing partners, or simply want to spend your Thursday evenings on the rock, these sessions are for you.

Every Thursday evening throughout the summer, we'll set up top ropes on a variety of routes and grades, giving climbers of all experience levels the chance to challenge themselves and connect with the local climbing community.

What makes these nights special isn't just the climbing—it's the people. We strive to create a non-judgmental space where everyone can be themselves, try hard, and celebrate each other's successes.

🧗 Guided by IFMGA Guide Steve Johnson and AMGA Single Pitch Instructor Chase Popp
📍 Boulder, Colorado
🕠 Thursdays | 5:30–7:30 PM
💰 $39 per climb night with punch pass options!

Come solo, bring a friend, or meet your next climbing partner at the crag.

What snacks do you always pack for a day at the crag? 👀

Here are some of our guides' favorites:
🍬 Nerds Gummy Clusters
🧇 Honey Stinger Waffles
🥭 Dried Mango (or any dried fruit)
🐻 Gummy Bears
🥒 Pickles (don't knock it until you've tried it)

One thing they all have in common? Easy calories and quick energy when you're spending a full day on the wall. Climbers tend to burn through more energy than they realize, especially when they're outside for hours.

Most of our climbing courses last approximately 8 hours, so we recommend bringing:
💧 2–3 liters of water
⚡ Electrolytes
🥪 A packed lunch
🍫 Plenty of snacks for throughout the day

Running out of food halfway through a climbing day is a mistake you'll only make once.
Now settle the debate: What's your go-to crag snack?

What do climbing certifications actually mean, and why should you care?

When you hire a guide, you’re trusting someone with more than your experience. You’re trusting their judgment, training, and decision-making in the mountains. At Summit Ascents, we have a simple philosophy: “No one should be guiding terrain they aren’t certified for.”

It sounds obvious, but that standard isn’t always followed in the outdoor industry.

Certifications through organizations like the AMGA and IFMGA require years of training, exams, mentorship, rescue skills, and real-world experience in specific terrain and disciplines. For us, certifications are about making sure you’re learning from someone who has been thoroughly trained and assessed for the exact environment you’re stepping into. Because good guiding is about creating a safer, better, and more educational experience for every climber who ties in with us.

June is packed with opportunities to get outside and climb, including our Thursday Community Climb Nights!

Skip the post-work routine and head to the crag. These evenings are all about getting outside, meeting new climbing partners, and climbing with an internationally certified IFMGA/AMGA Mountain Guide in a relaxed, welcoming environment.

Community Climb Nights take place on Thursday evenings all summer long in Boulder from 5:30–7:30 PM and operate through a punch pass system.

Whether you’re looking to build experience outside, meet more people in the climbing community, or just spend your Thursday evening on rock, we’d love to have you out there.

Belaying is one of the handful of first skills climbers learn. Most people learn it once, pass a test, and then rarely think about it again.

But great belaying is much more than simply taking in slack. A good belayer is watching how their climber moves, anticipating when they'll need slack, recognizing when they're entering a crux, and staying ready to react if something goes wrong.

They're also communicating clearly, managing rope efficiently, positioning themselves correctly, and staying focused from the moment their partner leaves the ground until they're safely back on it.

The truth is, the best belayers often go unnoticed because they're making every climb feel smooth, safe, and seamless. That's why we spend time teaching belay technique and safety practices in our courses. Belaying isn't just a box to check before you start climbing; it's one of the most important skills you'll develop as a climbing partner.

What do you think makes a great belay partner?

Most people think they need to get stronger before they can start climbing outside, but the truth is, you just need someone who can guide you.

Every climber starts somewhere. Not knowing the gear, the terminology, or even where to put your feet is completely normal. That's why guided climbing experiences exist.

A good guide helps you:
✔ Learn the basics safely
✔ Build confidence on the wall
✔ Understand equipment and techniques
✔ Focus on having fun instead of figuring everything out yourself

You don't need years of experience inside, or to invest in all the gear, or even to be able to do a pull-up (yes, someone thought they needed to do a pull-up before they could go outside).

You just need the willingness to try something new. We'll help with the rest!

Trad climbing is a pathway to bigger objectives, greater independence, and some of the best routes you'll ever climb.

Our Learn to Lead Trad course is designed for climbers who already have outdoor climbing experience and are ready to start placing gear, building anchors, and leading with confidence. Over two days, you'll gain hands-on instruction and practical experience in the systems that make trad climbing possible.

If you've been following trad routes and wondering when you'll be ready to lead your own, this course was built for that next step.
