My 6yo had a good intro to climbing here at Sender City. Had great service at the front desk…read more Facilities were great (restrooms, snacks, water machine, etc). The only thing may be that the other kids were more daring and advanced so they cycled through everything quickly while my kid took a long time working up the courage and solving problems on certain walls. Some kids seemed impatient for her to get off so they could go. But that's not the fault of this place, really. Could also have been a one-off experience. We look forward to coming back here

Came here for a birthday party and had a blast! I went to the Aliso Viejo location previously and a…read morenot-so-great experience. But the Santa Ana location was much better. There were actually staff available to help out, and the vibe was just so much better. It did take a bit for folks to get started with the harnesses and helmets, so the kids didn't have as much time to climb, which was a bit of a bummer because it took them a bit to warm up and gain some confidence with climbing! Sender City is pretty awesome and the self-belay system is pretty cool too.

He was patient and explained to Jackson (JD) and Leo what to do and what to expect. He spoke about safety and the proper way to come down after climbing, and about not hurting your legs.

I climb for fun and to make friends. The gym routes really help you prepare for outdoor climbing…read more It's also at a difficulty level that other gym routes will be easier to you. I took their Fighting gravity 2 and 3 classes. I've been climbing without "technique" or "form" since I started. I learned how to actually use my body weight and muscles right without putting bad pulling pressure on my tendons (to prevent injuries). The instructor Alan was real helpful! He has 10+ years experience climbing and teaching. Community is nice here. You recognize who is climbing after a while and you get to learn from each other and make friends (:

It was a little stressful for me because we had a large group of kids and there were other adults climbing, falling, and jumping, but the staff was so patient with the girls. Thank you!!!

Fun, thoughtful climbs, that are not entirely based on strength! Not the biggest fan of heights and…read moreI always find a few projects here to work on that are challenging and the finishes aren't all the way to the top. Good distribution of overhang and slabs. They have some fun holds too (aka baby heads LOL) Clean, well air conditioned so that it's not musty even when it's crowded. Expansive gym area and even a slack section! Parking is decently easy as it shares a lot with other businesses, especially if you come when those stores close, in our case at 6:30PM on a Wednesday. I opt for the 7 punch pass bc it comes out to ~$28 per visit and it's good for a year.

I feel as though the climbs are a little more challenging than their LAX location, with more of an emphasis on technique. I also really appreciate how nice the bathrooms are - the bathroom stalls go all the way to the bottom with ZERO gaps (something seemingly hard to find nowadays), and the showers are very clean. Overall between here and LAX, this is my preferred location to go to.

A decent Hangar 18 location, but if you're used to an expansive gym, this might not be for you…read more There is parking at this gym in the front. Plenty of spaces for you to park your car. They have a squat rack and an area for you to warm up. There are tables for waiting and a couple of rope problems. I think I'm not used to how small this gym is; probably one of the smallest Hangar 18 locations that I've been to. There are a variety of problems at different levels, but it's hard to get a chance to get on the wall with the small space. There's also a hole in the mat that I kept getting my feet stuck in near slab. Not the best size wise, but staffing is great and the climbers here are friendly!

So kids have this great sense of independence and being able to freely choose which walls to climb with minimal supervision. They're totally safe! I came here for a kids birthday party and there was a group of 6 to 8 year olds running around and climbing like crazy, all with big smiles on their faces. What a great time to be alive.

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.

Really was hoping this would be a great experience and honestly hadn't even considered it being so…read morelame. Walked in after work to do some bouldering while traffic simmered down, and to sus things out for my fiance who also climbs. Small but looked like people were having fun! I was met with SO much hostility from the front desk, thought I was hallucinating. Did their waivers and training video as expected, worker had left us to our own devices entirely. Huge line at the front, I'd been there at least 45 minutes at that point. Then I saw this adorable microscopic font sign, super endearing You could have just told me you don't take walk-ins, instead of being brazenly rude. When clearly that policy isn't even enforced. Other patrons who also walked in didn't receive quite as much vitriol. I was told I'd have to test out, no biggie, but nobody else was told this. Nobody else was asked "do you climb?" with a whole lot of attitude. Yeah I climb, and I enjoy walking in here looking like a corporate loser about as much as you enjoy seeing it. Just wanted to change into jeans and a t-shirt and boulder a bit. Might go to some other hangar 18 location someday, but won't be enthused about it. Not a lot of options around. Saw the sign and left because they hadn't asked me to pay yet, and I'm not paying for that attitude. I can only assume she was giving me attitude because I walked in looking all corporate, which is ironic to me because this is the most corporate looking rock gym I've ever seen. Y'all can keep it.

Everyone in my group enjoyed the course regardless of how far they were able to go. Gilbert and Emily were awesome instructors and made everything easygoing and fun. It might seem terrifying for those who have a fear of heights, but I can guarantee that they'll look back on how fun it was once they're able to conquer the obstacles. My arms are dead from latching onto the ropes with a death grip and I know I'll feel this tomorrow, but I'm sure the fun memories will last even longer.
