G1 Climbing + Fitness

I have nothing but good things to say about the coaches for the youth recreational teams. They are all amazing with the kids. They know exactly when to provide more support while also building confidence to do it on their own. Their exemplary support and teaching is invaluable for the love of climbing my kid has developed. Beyond the youth program, the gym is always clean and well ran. I highly recommend this gym.

Really nice gym, good route setting all around, and the staff is super friendly. Clean facility, solid regular work out room. Bouldering grades are super solid, top rope grades are a little soft in my opinion. Overall my favorite gym outside of downtown.

My 15 year old son and I love G1! Every single staff member is extremely friendly and helpful. I took the learn to climb class and now climb with my son. I also take several fitness classes which are all different and fantastic - great workouts with knowledgeable, friendly, and fun instructors. My son often boulders alone and is already making friends with all of the adults (young and older) and knows several by name. The members of this gym are all incredibly kind and helpful as well and my son wants to spend more and more time at the gym. Finally, routes are changed and updated weekly and so my son is always challenged, excited to conquer existing routes, and also see what's new. We cannot recommend G1 enough. It is fabulous in every way!

I cannot express enough just how special G1 is! Aside from the excellent route setting, fully equipped gym, and exceeding standards of cleanliness, the sense of community at G1 is unmatched. You are always greeted with a friendly face as soon as you walk in the door, and there is never a shortage of people around willing to share beta, give you a catch, or encourage you on your project. G1 is the only facility I've been to that hosts such a large variety of top tier classes and community events. I drive from south Denver multiple times a week to climb at G1, and it is worth it every time. a huge thank you to Jason and his team for creating such a positive force in the climbing community!

I love G1! Started during the pandemic when all other climbing gyms required reservations, G1 was accommodating and welcoming! The facility is impressive and the routes are always diverse and challenging providing various levels of difficulty for every level of climber. I love the Boulder area too! Community vibe is great and the staff are all amazing! If you haven’t gone to G1 yet, you’re really missing out!

I've been indoor climbing since 1994, and G1 is absolutely too notch. The massive 50' walls make for an exciting climb. No more following colored tape for the routes; the holds themselves are the same color to indicate the route.The bouldering area is robust with many levels of difficulty. And even the onsite gym with weights, rings, tread, and rower can help build the extra layer of fitness that you want.Great place for beginners to advanced.

G1 is the best gym in the Denver area (after checking most other gyms out), so glad this place exists! The facility is clean, staff friendly and competent, tall wooden walls, offers everything you might need besides autobelays, although I'm glad they don't offer that.. The really outstanding part is the route setting. Really high quality and interesting routes, frequently reset, clean and interesting holds. This gym holds up to The Front in Salt Lake City, but with less crowds! Thank you!!

Great gym, great staff. They gym is always kept clean, the staff are friendly. The routes are well rated and changed on a decent pace. The cave though is generally high 10's at the easiest. Only thing that could be better is keeping the ropes tied up but thats more on the climbers then the staff. Been members for over a year.

An amazing facility. Fantastic staff, and great community. Has a 2-lane 15m speed wall w timers which is SUPERB on top of some amazing sport/bouldering walls with a great fitness center. Prime location near plenty of eats for post-climb and good parking availability. One of the best facilities I have visited in the US! Great work G1 team!

I love climbing at G1. The facility is new and clean, and the staff is friendly. The community is great too. My climbing is improving thanks to the support of all of my new friends at G1. Would give 6 stars if I could.
