Sender One Climbing & Sender City - Santa Ana

Love Sender City! My 6 yo son has a blast and the staff is all very friendly and helpful. I especially like that the staff is masked and that most patrons of Sender City are as well.

Beware of their billing. When you call they tell you to submit membership changes thru the portal and then no one checks those queues. It took me over a month to get a simple refund when they overcharged me.It took me ~4 portal submissions, 4 calls and several emails for a simple billing issue which was their error in the first place.

I'm a climber of 7? years and a reluctant member of this gym... It's got tall walls, routes are set pretty frequently, there's a few cracks, and there's classes, fitness center, and training tools (campus board, hangboards, 2 moonboards and a kilter board). But it's clear that this gym prioritizes attracting new climbers over pushing existing climbers to get better. How so?1) The grades are soft, the setting is boring especially on ropes. Yes, gyms are softer than outside, but Sender's grades are a whole number grade (maybe more) softer than other gyms. Even the cone, until you get to like... 11c/d, it's just a jug haul, albeit a steep one.2) During peak Covid restrictions, members were restricted to one single 2-hour session a day, and long before members were allowed to climb for longer (2 hours is not enough!!!), non-members and new people (aka the $$$-makers) were returning to the gym. Meanwhile, other gyms like PG prioritized letting members climb for longer sessions first. I feel like this was a clear signal showing who and what Sender prioritizes.3) Why are the training center's hours so restrictive? On top of that, if the kids (aka more $$$ for the gym) are training on the boards, then good luck getting any time on the boards during your reservations.4) They're always churning through classes and clinics (which is great)... but they're misguided. There's "adult training club" and a plethora of classes for improving movement and technique.... This takes us back to #1 - why not just set better climbs that teach new people something?5) Finally, a petty one... Why are you guys always promoting your new merch??? Yes you're a business, but you're not a clothing store. You're a gym.That said, I do enjoy climbing here and always have a fun session. The staff is nice! The climbers are nice! The facilities are nice! I do also wish the other locations weren't all the way in LA...

I visited Sender One to boulder while visiting Orange County. It’s an ok gym, I would be reluctant to get a membership here but great for a visit!Pros:— definitely catered to kids/new climbers. The kid area was really cute— Decently sized gym, variety of climbsHere’s some feedback I have:— They were renovating the bathrooms and had two all-gender restrooms open. They were kinda dirty, didn’t feel super clean. There was pools of water on the bathroom floor which felt kinda bad haha— The mats are kinda hard compared to other gyms. They don’t have much bounce and I didn’t feel comfortable climbing to the top of walls and falling from that height. My friend was saying that the actual padding thickness seemed thinner than his gym too. I’m used to sinking into a mat as I walk — def felt more stiff than that!— It’s extremely hot. I wish they had more fans. I’ve never felt hot climbing at other gyms but was legit sweating through my pants!! They had some small fans around the space but they were turned off.— I wish they specified two hand start vs one hand start.— I wish they put their climbs on KAYA so I can track >:)

I and my first experience there recently.The staff was prompt, professional and kind. My daughter had sole fears and apprehension and Adithi spebt time calminf her. Also other staff members were great. There was a guy with long hair ( sorry I forgot his name) that did breathing exercises to help a kid gain confidence and jump down from one of the climbs. I was really impressed with the kid friendliness of the staff.I just wish it was cooler in there as it was quite warm in the climb room. I am not sure if the ac was down or if it was because of the number of climbers.Over all very clean place and enjoyable experience.

Update: been here since January of this year and still loving it!! My gf climbs with my guest pass every month and she also has her own punch card. She will most likely be getting her own membership sometime soon. I’ll also say that the staff have been nothing but friendly and respectful. They do an awesome job of keeping the place clean and in order, which I appreciate!Great climbing gym, lots of fun walls. Decided to get a January $0 initiation fee membership. I see some people leaving bad reviews, but their covid protocols are exactly why Im switching to sender from my current gym.

It's pretty huge. The kids section is super cute. There's a moonboard, campus board, weight training, other training equipment, etc. so you're gonna get pretty much everything. They have a huge wall for top rope and lead but I mostly bouldered when I went there so I can't comment on that. The setting is okay but I wish that some of the easier routes could be more interesting. I enjoyed climbing inside the bridge a lot. Also wish that there were more lights because sometimes it was a bit dark in some parts of the walls and I couldn't see very well. Overall pretty expensive so I'd say it's a great place to boulder for the day but I can't say I want to get a membership here just because of the price and that I simply enjoy a more intimate environment.

Thank you always a great time. Milton and Kimberly were great ambassadors and climbing teachers.

Sender is always a pleasant experience. The top rope, lead climbing, and bouldering are all amazing!

Great folks, nice climbing. Love it.
