My daughter (almost 4) has been involved at ABC kids since she was 2.5. We have had such a good experience with the classes and different instructors! We’ve done mini monkey, 1, mini monkey 2, and monkey 1! We have loved them all!! I love that you can start classes at 2.5 year olds too! I do prefer the weekday morning classes for littles if you’re able- the gym is less crowded which is super nice!

A.B.C: America's Best Climbing (I know it's agility balance coordination), but my version is better. Mine is far more descriptive and shows the gym's awesomeness in better ways. Incredibly fun boulder problems and auto-belays topped off with a top-notch training area. The coaches are phenomenal at instructing kids, and team members. My favorite gym by far!* *May or may not be on Team ABC

Staff is super friendly and want to encourage all climbers. The facility has lots of challenging courses and places for kids to play. It can get very busy during open gym, so be prepared to deal with all kinds of energy.

Cannot say enough good things about this facility and the guys working there. Took my 5 & 6 year old, first time climbers here for an open gym session and everyone was so friendly. They were extremely encouraging to the little ones and provided clear and easy instruction to help them improve as our visit went on. Would highly recommend coming here and if we visit Boulder again, will certainly be back!

ABC Climbing Gym is fantastic! We visited during open gym and our kids had a blast. Parents can climb for free and you pay for each child. The gym is very clean, the staff is friendly and our kids were entertained for hours! We will be back to sign up for classes in the spring!

My 8-year-old and I booked a guided outdoor climb through ABC Kids and couldn’t be more pleased with the experience. Our guide Matt was a blast to climb with - meticulous, patient, and knowledgeable not just about safety and gear, but seemingly recommendations for all of Colorado to give to us tourists.

This hidden gem rock climbing indoor park is amazing! We were visiting Boulder from Florida and our 6 year old wanted to try it out. She absolutely loved it! My husband and I want to open one where we live now! Lots of things to do for the kids little and big. There's a zip line and secret passage ways to get into different climbing areas that we all loved! Something for all ages to enjoy!

So many perfect scores and great reviews, let me join and add another one!! Why? 1. Professional classes at all levels, they fit the class to your kid level, not age!! 2. Easy to navigate site 3. Extremely kind people 4. They get us parents, no other venue does it as well as they do. Example: they allow drop offs, yes, you don't have to stay. Normally, you would want to stay and see your kid flourish, but in those moments when you, the single parent, need to run a quick errand, you can!! Thank you ABC, I have two kids with you and they are both so thrilled to come in every time!! priceless.

We came here for an intro lesson and it went really well. The gym was quiet at the time and there were so many options and great lessons. So far we're very happy this place exists!

Great kids climbing! Went for a 5 year old birthday party 🎉 we all had a blast even the parents. Very friendly staff, solid climbing and lots of kid friendly fun and excitement. Highly recommended.

Had the best experience! My daughter celebrated her 6th birthday here. We invited 20 kids and I believe 16 showed. The staff was wonderful. They kept the kids engaged and entertained. I can't say enough about how great the staff was with the kids. Highly recommend this place! I'm even going to sign my daughter up for classes.

Great staff to make a kids climbing experience fantastic. The rooms and areas make social distancing easy! Nice to not feel pressure or rushed! 12/2020: Enhanced Covid19 precautions. More frequent yet smaller classes. More thorough screening and checks at entry. More divided spaces to lessen possible transmission! Way to go staff!

My kids love this place - just wish there was a family annual pass. Drop-ins get real pricey with twins. Great place to have a birthday or join a kids climbing team.

Staff handed out harnesses to parents to put on their kids and then didn't have time to check they were on properly. They also didn't have time to stand next to the wall. Context: 3 year old kids climbing up two story climbing walls. Things staff did have time for: - Taking money from even more people entering - Making sure waivers that relieve them of liability were properly filled out - Rudely enforcing the "no eating before climbing" rule

It's really fun and had plenty of things to do. There are also different ranked climbs so it doesn't matter if you have experience or not! Everyone who works there has a really friendly attitude towards climbers as well!

Really fun and very reasonably priced for open gym. The staff was friendly and helpful. There were great climbing options for my kids ranging from age 6-16.

We were in Boulder for spring break and wanted a fun indoor activity to do with our 7 year old girls. They had never been rock climbing before. From the moment we entered, Stef made us feel welcome and put the girls nerves at ease. The gym is awesome and perfect for kids to learn and advance. We spent three hours here and the girls had an absolute blast. Couldn’t recommend this spot more. We will be back every time we are in Boulder!! Thx ABC Climbing for a great family experience.
