David Janis about Denver Mountain Guiding on 57hours

2nd time we have used these guys. Once with my 8,10,12 year old kids. And a 2nd time with some out of town experienced climbers. Both had an amazing experience. I am not a climber and do they were patient and knowledgeable.

MissMalieMaud about Denver Mountain Guiding on Trip Advisor

Denver Mountain Guiding was an incredible experience. Our guides, Joey and Carlyn took us to a very scenic destination where they set up two climbing lines. They taught us how to belay, rappel, and climb. Eventually, some of us got the hang of the beginner routes, so they set up a different route for us. Our guides were helpful, friendly, and funny. Would definitely recommend!

You can't find a better outfit
Allen H about Denver Mountain Guiding on Trip Advisor

Where to start? My guide Jason, amazing and very interesting guy. Easy to understand and a great teacher. Very patient and knowledgeable. Makes you feel like a friend not a customer! He wants to teach you everything he can in the allotted time. Always asking if you have questions. Always gives a clear and honest answer. Well known in the area for sure, you can see instantly from others that know him how much he is liked and respected. I couldn’t imagine a better guide/teacher. The location was excellent, easy to find. Price was very reasonable. I highly highly recommend Denver Mountain Guiding and even more so Jason! I will be back for sure. I wish I could have attended the anchor clinic coming up.

Amazing climbing experience
MorganO9189GF about Denver Mountain Guiding on Trip Advisor

We had a blast mountain climbing. Our guide, Nate, was amazing. I was nervous about my upper body strength but he quickly eased my fears and showed me how to use my legs and footing to help me get up the mountain side. Nate was so patient. He gave us tips and confidence and made the entire experience so incredible. Nate also showed us how to belay and taught us the ins and outs of safety so we had the skills to go to a gym and keep practicing this sport. We also felt so safe, Nate took COVID precautions seriously which made our experience so much more enjoyable. I highly recommend going out with him on a rock climbing trip!

How fit do I need to be?

For this rock climbing adventure in Colorado, If you can climb a ladder, you’re good to go. Being in good shape is always a plus but far from necessary. Rock climbing is all about using good movement technique rather than muscling up a cliff using brute strength. To ensure you have a fun day, your guide will choose routes that best suit your skill and fitness level.

What if I’ve never climbed before?

No prior experience is necessary. Whether you’ve never donned a harness or you’re a seasoned climber, a guide will help you meet your individual objectives. Above all, your instructor’s number one priority is your safety. As long as you listen to the given instructions, you’ll succeed in completing your climb.

The Flatirons have plenty of options for beginner climbers. Whether you’ve never climbed before or are transitioning from the gym to outdoor climbing, your guide will customize the day to suit your skill level and objectives. With a guide by your side, you’ll learn something new, stay safe on the rocks, and most importantly, have fun!

For intermediate to advanced climbers, the Flatirons have loads of routes to spend the day on. Your guide will discuss your objectives and customize the day to your goals. Let your guide plan the day so you can focus on developing your skills while climbing the classic routes or best hidden gems the area has to offer.
