I went there for a yoga workshop and the yoga studio was upstairs. It was absolutely beautiful and the instructor Amanda was amazing. Her workshop was not only a lot of fun, but I learned so much!

Had a great time at Hangar 18's Intro to Bouldering. As a first-timer, the intro class was quick…read morebut informative, and I could tell that safety was a priority for the facility and everyone working here. I thought the bouldering routes were pretty decent and had a nice range of difficulties, but the auto-belay routes were definitely hard-- There aren't many suitable for beginners. It's not easy even if you're in-shape and athletic; I hit the gym regularly and thought it wouldn't be too bad, but it was still quite hard! There's a review on Google that walks through all the different Hangar 18 facilities in SoCal, so maybe consult that first if you want to find a place with easier routes (or just more varied difficulty). Keep in mind that even though it's an indoor facility, there's no air conditioning. It's a little hot, but not too bad with the fans running.

This location is my second go to Hangar 18 gym. Located near downtown Upland, you maneuver through…read morethe industrial area in order to find the gym itself. Parking is not the best especially during peak hours; I find myself parking inside the residential areas just to come to gym. They have auto belay, a top out area, and a very large bouldering section. They don't have a super long slab wall, but they do have a wide variety of problems and types of boulder holds. As an avid v4 climber, I think the routes here a fairly easy for my grade, yet the problems are very fun in itself. The interior is very clean and the workers are diligently checking the gym, restocking, and cleaning restrooms. They have merchandise for purchase, too. On very busy days, the students from the colleges are here to climb. I'd avoid climbing in weekdays after 3 PM if you want more time on the wall without competition. Other than that, it is a nice gym with nice workers.

It was almost 20degrees cooler up here. I needed a sweater for the day especially while climbing in the shade. There is a good mix of trad,sport and bouldering. This place is known for its sport routes but trying to navigate the mt project app to find routes I ran across tons of trad routes. Left the trad gear at home n was bummed I did. The approach to climbs was super easy 10-15 minutes hiking through well marked and nicely groomed trail. I look forward to carrying both my trad and sport gear up here for a fun filled day of climbing. I love short approaches and there are numerous grades to keep every type of climber happy.

It's clean and has what you'll need…read more Classes offered works for most people, although, I usually hit the weights and run thru the mountain trails, I have done the yoga classes and I'd go back if I had more time. I'd only rate it higher if it were 24hrs so I could go at 2am but I understand that that is unreasonable on my part due to funding and student employees'schedules. POSITIVES It's close, if you live in the area, since there's no other decent gym that can compare. The attendants are friendly.. Not expensive if you're not affiliated. People are cooperative if you ask for a spot. Good place to find a workout partner if your looking for one. Great activities at reasonable prices. NEGS My only beef with the gym set up is that all the bench presses need to be pulled away from the windows bcs it's impossible to replace or remove the 45lbs plates w/o struggling. Some attendants should stay on the floor supervising in order to ensure that all weights are returned and workout stations are broken down. Sometimes there are people that have absolutely NO clue what they are doing so some should ask for some initial workout instruction assistance w/o feeling embarrassed. But really, these are minor gigs bcs I keep high standards when it comes to gym etiquete.

They have plenty of equipment and personal training at a ridiculously affordable price (Emily is the best!). My only complaints are the blasting air conditioning (I try to avoid the invasive vents, anytime I am positioned underneath one I leave with a sore throat) and the hours.

They offer both top-rope climbing and bouldering, and both require an orientation--which I appreciated as a first-timer. I was surprised by how many people were bouldering, from novices to very experienced climbers. There's also a small gym with basic equipment. Overall, it was a fun, spontaneous activity for a random free day--kind of like bowling, but more physical and engaging. Definitely requires some strength and problem-solving. Would absolutely come back!

Well, the 30 min class turned out to be only a 5 min introduction to the rules of the rock climbing place and the only technique taught was how to fall. The instructor hastily dismissed the kids and said "Have fun". That was basically it. i thought the class would cover more bouldering techniques. I have just pulled up the class description (see pic). Had I seen this while we were there, I would've spoken to a manager about this. This is not right at all. The instructor only spent 5 min with our kids. There was only so much the girls could do on their own with that inadequate 5 minute "lesson". It could have been a fun playdate if they were given more instructions so they could've done more than climbing up 3-4 steps on just the 2 easy routes. 1 star and not likely to return. You did not deliver what was promised and wasted our time and 25 bucks each. Poor business practice. Thumbs down.
