    Kid on rock wall

    My son and daughter joined the ninja gym last week and absolutely love it! I've seen my daughter's confidence grow in just two sessions when trying new things and it's been amazing. All instructors have been so caring and patient with my kids when they're acting like normal squirrel chasers and running off to something else. They ask every day if it's time for ninja class. Spreading the word because we've had a really positive experience so far.

Because they are working with important stuff pertaining to national security, nuclear materials and other top secret stuff, they won't let the average Yelper in there. But, right outside their front gate is the Discovery Center. The Discovery Center is a small museum that gives you a brief introduction to the lab and what they do. They have hands on and interactive exhibits for children to play with. Most of the exhibits were well maintained. It is an interesting way to spend an hour. The staff, at least on the day were there, was fantastic. Since we were the only ones there, she almost gave us a personalized tour to explain some of the exhibits and talk about the lab and what they do. They have an easy scavenger hunt for children with a nice t-shirt as a prize. They are pretty generous with the scavenger hunt and let children of all ages play. The museum is priced just right for most Yelpers. It is free! It's a nice place, with not a lot of visitors.

    Went to Peek-A-Boo Factory in Livermore on the Sunday before Memorial Day and surprisingly it was…read morenot packed at all, which honestly made the experience way more enjoyable. I was nervous about bigger kids accidentally pushing my baby while running around, but it felt comfortable and manageable the whole time. The slides and play structures were really cool and my little one had such a fun time running around and exploring. I especially appreciated that they have a separate toddler/younger kids area which made it feel safer and less overwhelming. As a parent, I noticed the staff did a good job keeping things organized and the overall environment felt pretty clean. There were also plenty of places for parents to sit while still being able to watch their kids play, which I appreciated. But it's either my hubby, I, or the both of us with my baby the whole time. Parking was easy too and check-in was pretty smooth. I do wish the place was a little bigger, but I also understand indoor playgrounds are probably expensive to maintain and operate these days. Overall, it was a fun experience and my baby left tired and happy which is always a win. Would definitely come back. Just wish there was a location closer to Morgan Hill!

We got lucky, we were the only ones here so we had the whole playground to ourselves. The place is really big and their jumpy things are in great condition! They have lot of little areas to jump and play. The girl working the front desk was very friendly and informative and helpful. The bouncy houses are so much fun! The smell of cleaning solution is very faint but still enough that you feel confident they clean often which is nice. This place is great if you need to kill some time with kids on a hot day!

They put up the banners and did the tablecloths, which I was not expecting but very impressed. All our guests loved the place and had an amazing time. We had some slightly older siblings that also seemed to be enjoying everything also. We did the 2 hour party but I wish we did the private party for longer. There was a random kid that wandered into the party area and also an elderly woman and a baby that was not part of our party. They have a cart for the presents, but I would suggest offering a cart to bring in the decor & cake as we had to make a few trips. We had such a great time at the venue, perhaps we can repeat for next year!

    This place is undeniably creative and fun. My kiddo absolutely loves it here, and I can see why…read more The play areas are imaginative and engaging, and when things are running smoothly, it's a great spot for younger kids to explore and burn off energy. Other reviews are spot on, though. The lines can get long, it feels overcrowded pretty quickly, and the staff doesn't seem particularly engaged (at all). None of that is ideal, but honestly, I can look past those things. My biggest concern is the age range. During our visit this morning, there were several older kids (around 10-12 years old) tearing through the play areas, running up slides clearly marked not to do so, and pushing past both adults and younger children. I watched two babies get knocked over, tears and all. While I believe parents should absolutely manage their kids' behavior, the age gap itself feels like the core issue. Having toddlers and babies in the same play area doesn't feel safe. I understand the challenge: families with younger kids and older siblings want a place everyone can enjoy, and birthday parties often include mixed ages. But the reality is that older kids are naturally more rambunctious, and there's nothing wrong with that. This space just isn't designed for them. Ultimately, it feels like an accident waiting to happen. Great concept and a hit with younger kids, but the lack of age separation makes it hard to feel fully comfortable from a safety standpoint.

At $80 per child for the most basic package on a weekend I expected a higher level of service. Throughout the party, I had to ask for everything. I had to request water pitchers, ask for a candle and lighter, and no one offered to help cut the cake. The staff didn't offer much help coordinating the event. I've had parties at Pump It Up, where the staff was much more attentive and proactive. I also had an unpleasant interaction with an employee (Scott?). The employee's old white car was parked in front of the facility, with its windows completely down and a cracked windshield, and its alarm went off. The employee came outside, WALKED ON THE HOOD OF HIS CAR to turn off the alarm, and then accused me of hitting his car. My husband and the five children in my car all confirmed that I didn't. After confronting me in the parking lot, he walked back into K1 while I followed behind. I found it very inappropriate for an employee to yell at a customer, especially as they were entering the business. The kids enjoyed themselves, but the overall customer service was not up to my expectations. When I book a party I like to be stress free, otherwise I would just host a party at my own house.

We visited on a Sunday, and it wasn't too crowded, which was nice because the kids had plenty of room to play. They also have party rooms available, and the rooms are a good size for birthday celebrations and group events. My only suggestion is that the food court service could be more attentive. It often seemed like no one was at the counter when assistance was needed. Overall, it was a fun experience, and I'd recommend it for families with young children.

We were informed that adults are NOT allowed on the second story of the play structure and cannot accompany our child on the slides. Our 21 month old had to stay on the first floor the whole visit. She started getting upset that we wouldn't allow her to follow the other kids up to the slides. I asked an employee why we couldn't go down the slides with our daughter and she said per new ownership, they changed the rules. Except recent videos (as of today) on social media of people advertising this place show adults going down the slides. We also witnessed adults walking around the top floors with their kids and going down the slides. It seems that the rules aren't applicable to everyone. Tons of balls in the ball pit were deflated, the ball cannon shooters were not working and that's pretty much all there is to do if you stay on the ground floor. Older kids can play in the ball pit and it's simply way too small for that. My daughter was terrified of the older kids running and jumping into the pit around her. It was a rainy day outside and very crowded. I asked one of the floor workers if she could turn on the giant overhead fan to help move some air around since it was very muggy and warm and she said she had to ask the owner first. She even admitted she was getting hot as well. 20 minutes went by and it was never turned on. I guess it doesn't work? Not sure why you need to ask the owner for permission to turn on a fan. The layout could use a little rearranging. It's a cool concept, just not executed nearly as well as others with the same idea. For the price, $40-ish for two adults to accompany their toddler, it's absolutely not worth it. We won't be returning. Also keep in mind, if you order tickets and sign the waiver ahead of time, you'll still have to wait in line behind people who didn't. Just one person in front of us with one child took 15 minutes to buy their tickets and sign the waiver. Once we were checked in which took less than 5 minutes, the line was out the door. There are also no lockers to safely put your belongings in, just open cubby's.

    Staff was super friendly and helpful. She signed us up for a 30 day membership, using the price of…read moreour daughter's GLOW hour to purchase it (the balance remaining was $0. to be paid). Our daughter can come every day, at any time including GLOW, for free during the 30 days. There are SO MANY zones here, including an iWall (interactive running, dancing, poses, etc), a cycloBEAT (two stationary bikes to race flying through obstacles, racing over water and on streets, etc), Dodgeball, Double Mega Launch (two HUGE slides to go down), Freestyle jump (jump, spin, flip, play), Air court (play basketball, soccer, volleyball and more dodgeball), and Toddler zone (a smaller jump area to run up walls and over obstacles for tots). There is a dinning area and snack bar with various treats and quick eats like pizza and nachos. There is an enclosed open party area to host a birthday, lots of arcade games, clean restrooms, oversized comfy chairs for parents to observe from and massage chairs to pamper while the little play. We will return during the 30 day pass and dependent on the usage we may purchase the annual membership ($259), which is half off a 12 month membership month to month at $43.99 (based on an Extra Play membership). The Basic Play membership is limited at $36.99 and offers 50% off GLOW (vs free as Extra Play). GLOW is a BIG DEAL to our daughter so that's a must have for us to have included. GLOW, at this location, does not begin until 8 PM.With so many other kids playing, our daughter bounced between kids to play with and enjoyed a couple longer than others. At 9:15, majority of the kids our daughter was playing with were gone. With the drastic decline in playmates and the closure of one zone it dampened her spirits. The late start of GLOW will likely be our greatest reason for not becoming members. We tried it on a Saturday this time. We will try again on a Friday to see if there is any difference in play and length of attendance. Overall, such a great experience with updated, modernized play spaces for big and little kids alike.

    A Chaotic and Concerning Experience -- Not the Birthday Celebration We Expected…read more I attended my great nephew's birthday party at Sky Zone yesterday, and unfortunately, this was one of the most poorly managed children's party venues I've experienced. My children are now young adults, so it has been a long time since I've been to a place like this--but even with that in mind, the disorganization was shocking. My niece had reserved a party room for 3:00 PM. The day before, she was told the reservation had been moved to 3:30 PM. When we arrived at 3:30, staff informed us that the room wouldn't be available until 4:00 PM. Even then, nearly an hour later, there was still no indication the prior group would be cleared out. To make matters worse, several other rooms sat empty, yet staff refused to open any of them for our group. The entire facility felt chaotic, overcrowded, and understaffed. What concerned me most was the complete lack of security protocols. There were multiple entrances and exits with no employees monitoring who came in or out. Adults were not checked in or connected to a child, which is extremely unsettling for a venue filled with minors. At similar venues we visited when our own children were young, adults had to be verified at the entrance, and children were not allowed to leave without a designated adult. None of that existed here. Cleanliness was another major issue. My husband reported that the men's restroom was in such poor condition that boys were missing the too-tall urinals and urinating on the floor--while children were then running through that area in their Sky Zone‑issued socks before heading back to the play spaces. That alone is unacceptable. The women's restroom, thankfully, was clean and quiet, but it was the only part of the facility that felt remotely controlled. I will say that the kids had a wonderful time, and I'm grateful for that. But as a parent or guardian concerned about safety, organization, and basic cleanliness, I cannot recommend this venue. Sky Zone needs significant improvements before I would ever consider returning.
