A couple weeks ago my husband and I went climbing with a guide, Meg Yingling, in El Dorado Canyon and had the best time! Colorado Mountain School made it so easy and convenient to book a guide and we were so lucky to be placed with her (although I have no doubt the rest of their guides are wonderful as well.) Meg was incredibly experienced, knowledgeable, patient and helpful as well as just so much fun to spend time with. This was our first experience with multi-pitch and trad climbing, and we couldnt have picked a better person to do it with. We cant wait to go out with her again the next time we are in Colorado!

This is our second time using Colorado Mountain School and once again our family had THE BEST time. Scarlet was an EXCELLENT guide! Mary’s lake location she chose also provided beautiful views and several climbing opportunities to keep our group interested and challenged.

We had an amazing corporate event with Colorado Mountain School! They did a great job setting up a day that everyone could enjoy regardless of skill level. Rainbow and the crew were all incredibly welcoming and kept us laughing while also ensuring we were safe. Highly recommend if you’re looking for a great outdoor event for the office!

Great Experience! I used to mountain climb centuries ago and havent touched a rock since then. This year, I decided it was time to go back to the activity that gives an incredible amount of joy, a sense of achievement and pushes you to your limits.CMS and my guide Tyler Allen provided smooth and steady immersion to rock climbing. From going through the basics of rock climbing and belaying techniques on day one to climbing the “South Ridge” on Notchtop in Odessa Gorge on day three, I felt supported and in the same challenged with a new adventure.I can highly recommend CMS to anyone who is looking for upgrading their climbing skills or having an adventurous day in the mountains under the supervision of a highly experienced guide.

I did a 2 day intro to mountaineering course with Ian Fowler.There are not enough words to describe how awesome those 2 days were and how amazing Ian has been as a guide to learn from. Ian was super knowledgeable and patient and I learned so much during these 2 days. But most importantly - I was left with a taste for more mountaineering and I am eager to learn more and do more! 5 stars!!!

If I could give more stars, I would!The office staff at CMS is excellent: eager to help folks complete successful adventures. My mountain climbing experience with Jason was absolutely outstanding. Hes an expert, a pro, in every possible way without a hint of condescension. Patient, skilled, directive, supportive... the list goes on. I am literally already thinking about new adventures to take on, JUST so I can work with him again. (Ice climbing, anyone?) I cannot recommend him or this organization highly enough.Dont hesitate. Figure out your next big thing and ask CMS to help you make it happen. Theyre worth EVERY penny.

I booked the 1/2 day fun climb in Estes Park, and it turned out to be one of the highlights of my trip. I had only climbed in gyms before, never outdoors. The instructor was professional, patient, and encouraging. I learned a lot and had a great time!

These guys are amazing. Thanks for a great day.

What an exciting and eye opening experience for my first alpine climbing trip! Sarah, our guide, did a great job taking us through the day. The learning curve for becoming proficient at alpine climbing can be quite steep. Sarah was so patient, providing a lot of tips throughout the day and I feel I learned so much! I still have a ton to learn but Ill be much better prepared for my next alpine climbing adventure!

We had an amazing intro to rock climbing with Andy. We had no experience, practically out of shape, but we climb the rock multiple times with confidence, thanks to Andy’s thorough guidance!

Have taken two courses with them over the years and have had outstanding experiences both times. They have been physically demanding but very educational and rewarding. As I progress in my knowledge, I will be taking more classes from them in the future

From the moment of my first call for information to our familys last climb, CMS was fantastic. They led me through the options, helped design a week of climbs around our planned destination, and coordinated with us around weather and gear. I felt safe and prepared, and we had a great trip. We are already planning a return to take it to the next level!

Jason Antin was our guide on the flatirons and did an AMAZING job. Jason was very upbeat, fun, and extremely capable. It allowed our team to focus on the experience and the challenge instead of the uncertainty of the logistics and the concern that we werent properly planned. Would absolutely work with CMS and Jason again...

I live in Boulder and have used the service at least 15 times for my teenage daughter and myself. The guides are well trained and the front office people are fantastic . I wanted a female guide for my daughter but she was so great I just used her for myself too. I have nothing bad to say.

Our guide, Bernardo, lead us up the fandango route on the first flatiron. We had a great day of climbing. Bernardo was very knowledgeable and we were very confident in his skills and abilities. We highly recommend the Colorado mountain school.

The team at CMS was a pleasure to work with for a group day out climbing in Boulder Canyon. Shout out to Meg for being a great guide for our group!

CMS and the team have been awesome. I went on my first ever guided climb with Jason Antin and couldnt have asked for a better experience. Jason focused on my specific climbing goals throughout the day, had a ton of knowledge of other climbs in the area and ways I could improve, and made sure we were 100% safe throughout the climb (and also made the experience really enjoyable and positive!). Ill most definitely be back to climb more with CMS and Jason!

Awesome guides, Buster Jesik, Sarah Janin, and Tyler Allen took us up Longs Peak cables route. They couldnt have been more friendly and knowledgeable. Highly recommended experience. Definitely looking forward to my next trip with CMS and this guide team!

I recently completed the Intro to mountaineering course. It was an amazing experience. Very well organized, professional, and safe. Our guides; Mike Coyle and Josh Burke where extremely knowledgeable. They had a great way of keep the intimidation factor down, while making sure we were prepared to execute the objective. I plan on using CMS in the future.

My favorite mountain school in Colorado, they have very competent and friendly guides. Jake Gaventa was my guide two times of rock climbing and both were awesome hes the best mountain guide, very patient and always easy to spark a conversation with. Hes very eager to teach everything he does and careful that you learn something everytime you go out with him. Youll definitely enjoy your time with the school.

Knowledgeable guides and well-organized. I got everything I wanted out of my multi-pitch course, and more! I would definitely take another course with CMS. Thanks!

If I could give this a 10/5 I would. My partner and I had the BEST TIME EVER. We booked with CMS as we were driving cross country from Michigan->Cali. We normally climb in West Virginia and one of our favorite guides recently joined the CMS team this summer and we knew we HAD to visit. We booked a half day trip with the wonderful Tyler Allen and did the first Flatiron in Boulder. We woke up at 6am to beat the heat (HIGHLY recommend) and just loved it. Since we were traveling we did not have all of our gear but CMS provided me with the shoes, harness and helmet I needed. I felt safe, comfortable and challenged in the climb in the best way possible.Do the climb. Wake up early. Enjoy yourself. and also.. tip your guides!

I attended a 2 day intro to mountaineering course and it was fantastic! We worked on skills the entire first day, and put those skills to the test on my first climb ever on day number 2! I couldn’t be more happy with the experience! The instructor Jesse was extremely knowledgeable and safety conscious. They provided the equipment needed, and took me through the entire process from preparation to summit! I will definitely be working with the Colorado mountain school in the future, and I would recommend them to beginners and experienced climbers alike.

I have always wanted to go Ice Climbing and finally decided to do it through the CMC. Very efficient in the paperwork and straight forward on the gear required for the first trip. Rental gear was in great shape. The guide/ instructor (Mia) was superb; excellent in teaching the fundamentals while providing the guidance required to keep improving on technique throughout the day. The student to guide ratio was spectacular. It was a perfect day. Thank you.

I took my SPI course with Wes and it was so much more than I anticipated. I learned so much over the course of 3 days and Wes is on point. The dude is super professional and is a master of his craft. He changed our location from Boulder to Vedauwoo and I was super psyched he did. It was not only a way better better environment to teach and learn in but overall was a great camping and climbing trip! Wes is hilarious and super friendly to everyone he encounters. Really easy to get connect with and really open to questions and helping you learn the way you learn. 10/10 would recommend!

Josh was a patient, fun instructor. Two of our group had never climbed outdoors and walked away from the experience excited and feeling like theyd learned a lot.

Intro to Mountaineering May 8-9, 2021. EXCELLENT! Awesome Guides, great Instruction, beautiful weather! Best Guide Service!

We booked with Bob at Colorado Mountain School for a Guided Ice Climbing experience, and absolutely LOVED it. Bob was so encouraging and knowledgeable and made the whole day truly worthwhile. We are beginners, and his energy made us feel much more comfortable. I cannot recommend this experience enough!

An excellent guided climbing experience! I went on a couple half-day climbs out at Eldorado Canyon with two different guides (Bernardo and Mike). Both are very professional, friendly and safe. Highly recommended if youre looking for a guide in the Boulder area.

I had an absolutely epic day in Rocky Mountain National Park with my ski mountaineering guide, Ben. He customized the day to my exact needs (I wanted to learn more about skimo and also glacier travel techniques). We climbed and skied 3 big couloirs with awesome snow! Would highly recommend.

Absolutely outstanding! Our instructor, Japhy, was not only exceptionally skilled, but was also a great teacher. Highly recommend.

I cannot recommend Jesse, Bob, and Bernardo at CMS enough. They were kind, patient, knowledgeable, and extremely fun to learn Intro to Mountaineering from. On day 1 we were taught all of the techniques needed to safely travel on snow in the mountains. On day 2 Jesse took us up a beautiful route on Hallets Couloir that rewarded our challenge with incredible views and an unforgettable experience. We will definitely be back for more courses with CMS!

My husband has taken 5 courses and I’ve joined him for 2 of them. All of the guides have been fantastic. We’ve learned so much from CMS! Everything is very organized and professional. We can’t wait for our next outing with CMS.

Megan Yingling guided my first climbing trip outdoors on April 3, 2021. She was very knowledgable of the Eldorado Canyon State Park area and all of the routes in the park. As a first time outdoor and roped climber at the time, I felt totally safe and confident in Megan’s hands. Megan also gave me some rundowns on skills such as tying a figure 8 knot, lead belaying, cleaning and placing gear, rappelling, and setting up and cleaning anchors. She was super friendly and easy to spend a day with. I highly recommend Megan to anyone looking to finally get outdoors for the first time!

If you are considering big climbing objectives, getting back into it after a lay off, or new to it all—you need this class. No two emergencies are the same but through this class you will learn a systematic approach to address them all. Our instructor Jason was friendly, knowledgeable and has the resume to back up his instruction. Save yourself and your partner the epic and take this class.

A really enjoyable experience! I’ve skied/snowboarded my whole life, but never in the BC. The Intro to Backcountry course was a great first day; guides were communicative, effective and managed the variable of skill sets in the group well. Certainly intend to book with The Colorado Mountain School again in the future.

I very much enjoyed my recent Classic Ski Tour trip with CMS. Our guide, Buster, was very professional and knowledgable. We skied some fun terrain and I got to push my skills. Definitely worth the time and money!

My wife and I have done 5 different clinics / courses / private guiding outings with CMS and various guides. Colorado Mountain School never lets you down. The professionalism and level of instruction is consistently amazing. Ive used 6 other guiding services across the US and Canada and CMS is top of the field in guiding.

Great experience with exceptional instructors/guides. I look forward to completing other courses with Colorado Mountain School.

I had a fantastic experience and would recommend this to anyone interested in learning more techniques to increase their safety and overall knowledge. Mike S. was unbelievably patient and professional! He was able to give me right amount of information based on my experience and build on it. Thanks for the great time! This is exactly what I wanted!

My friend and I had the best weekend learning some mountaineering skills. Our guides, Jesse, Wes, and Jason were fantastic—they were so knowledgeable and highly skilled while also being really good teachers. They adapted things to everyone’s pace and interests so everyone in our group learned a ton. I’ll reconnect with CMS and these guys again for AAIRE 1 and maybe some guiding.

Had an excellent experience today sharing a crag with CMS guide Max.He was very professional, helpful, and overall a very good guide. After this interaction I would recommend CMS to anyone in search of guide services in Colorado.

My experience with CMS and guide/ instructor Dave K. surpassed expectations. The online work was in-depth and set the foundation for our field work. Access to the forums and google meets allowed for more exploration and specific questions.In the field work, our guide Dave K. was professional, effective, fun and eager to share his wealth of knowledge and experience. He established the team mindset from the start. Really could not have asked for a better learning experience.I feel confident in the foundation of science, observations skills and practical process to begin exploring the backcountry respectfully and safely. I will continue to work with CMS to further my skills and knowledge. Stellar Dendrites all the way!!!

Had a blast learning a bout Avalanche Safety with Everett over the weekend. Great place to take your AIRE 1

Joe was a blast to be with for a day in the backcountry. He makes everyone feel comfortable, is patient and gives helpful information throughout the trip. I would absolutely use CMS and Joe again!

Had such a great time rock climbing. One for sure be in the books. Ian Fowler was so accommodating and exceeded my expectations. Will surely be back!!!

A fantastic course! The instructors fulfilled every aspect that I wanted to learn and a lot more. I now have an understanding of how to plan a tour in the back country safely and how to avoid the risky areas. Well presented and highly entertaining! Highly recommended.

Took an AIARE 1 course from CMS and absolutely loved it. It was a great experience and I learned a ton about avalanche safety and backcountry travel. I highly recommend CMS!

We had a great time with our guide, who was informative, stoked, safety-oriented and very knowledgeable. We will be using CMSs services again in the future as we make the transition from primarily gym-climbers to outdoor climbers!

Great experience! I did the 2 day Intro to Mountaineering course and it was an absolute blast! Definitely recommend booking a course or guide through The Colorado Mountain School.

The go to for guiding and courses in CO

I stayed at the Colorado Mountain School for a couple nights during the week in August. It was a fairly quiet time of year which I enjoyed. The staff was very friendly, knowledgeable, and welcoming. I enjoyed getting to meet people with similar interests that were passing through. You cant beat the price, location, and atmosphere. Everyone was very respectful and my stay encouraged me to fall in love with Estes Park!

My son and I hired a guide for a day of climbing in Eldorado Canyon. The day could not have been any better. Our guide was very professional, as a guide should be, but also engaging and fun, which made the day that much more fun for us.I highly recommend Colorado Mountain School for a safe and enjoyable climbing adventure.

Great trip! Great guides!

Love Colorado Mountain School! The guides are THE best!!
