Best Climbing Gym near Rancho-cucamonga, California

Friendly place to come bouldering! Was in Ontario, CA for work and looked up this gym. They only have boulders, no ropes! Everyone is nice and it was a good time! I came back a second day with my coworkers and they had a great time!

I started climbing 6 months ago. This gym was my first intro to bouldering. The staffs here are awesome! The boulders are set for beginners up to advance climbers. Super friendly environment! Ended up making a lot of new friends and having a blast!

Nice clean cozy bouldering gym. If you just want to work on bouldering, improving strength and some cool routes without too much extra amenities, this place is great to workout in.

In my opinion, the best hangar 18 gym, with cleanliness and fun route settings. I used to think the grading was softer here few months ago, but after visiting multiple time, I noticed that the gradings are fair and square :)

Great Hangar 18 Climbing location. I really liked this Hangar 18 location. It is very spacious and clean. I also noticed that this one was very well-ventilated and didn't feel stuffy at all inside! The staff here is so friendly and I really enjoyed my experience here. It is good to note that this Hangar 18 is for Bouldering ONLY (i.e. no use of harnesses as you are only 10-12ft. off of the ground). The floor is all crash pads for when you fall. I personally enjoy bouldering a lot so I love that there are so many options. There are plenty of beginner friendly routes here too, so bring everyone!
