If you want to cross off the big hard bucketlist climbs, then our learn to lead trad is the starting point that makes them possible.

Most of the bigger adventures we guide that include multi-pitch routes, exposed ridgelines, and true alpine objectives require more than just fitness or stoke. They require comfort moving on real rock, placing protection, building systems, and making decisions on the wall.

That’s exactly what our Learn to Lead Trad Climb course is built for.

Over two days, you’ll step into the foundations of traditional climbing. Learning how to place gear, build anchors, manage risk, and climb with real confidence in the vertical world. It’s the skillset that turns “I want to do bigger climbs” into “I’m ready for them.”

And once you’ve got that foundation, the mountains open up in a completely different way.

📅 June 27 & 28

If you’ve been eyeing bigger objectives this season, this is where you start building toward them.

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?
