Very fun for the whole family! Plenty of space, areas and slides for everyone. Greta place for not just young kiddos but older kids and adults too. Great atmosphere and easy instructions even for younger aged children. Clean and safe overall. Staff was friendly and seemed to be checking on everyone to ensure safety and cleanliness of the area and mats. read more

The check in process to purchase a ticket here is ridiculously long. Even if you have your waivers already filled out. We had about 4 people in front of us and it took us 20 min to make it to the desk. As if that wasn't already annoying, if you are wearing grip socks that are not Slick City grip socks, they make you purchase a new pair for $4.50. What a money grab and a waste of money, not to mention adding to the overconsumption and waste. You need to improve your check in process or have kiosk's for easier check in. And let us wear whatever grip socks we already have read more

I came here on a Sunday with my kids. It's true what the reviews say about making sure to get here when it opens on the weekends. The place gets packed very quickly, starting around 12-1pm. You will get to enjoy no lines, or very quickly wait times for each of the slides if you come right when they open. My kids that I took with me are 10 and 13 years old. They both felt that the slides were fun, with only one being slightly scary. Most of the slides are larger park slides where you simply just slide down head first on padded mats. The most adventurous slide was the curved yellow one that was as a steep incline down and propels you onto a crash landing pad. For the experience and the slides, I would rate this a 4 stars. However, they lost one star since I had a bad experience with their customer service. They are currently running a "Christmas in July" special. You can buy 5 or 10 passes for a volume discount. It specifically states on the website that multiple individuals can use the pass. To confirm, I called into the number before purchasing to ask whether I can use all 5 on a single day with different individuals, and the rep said yes. When I arrived, the assistant manager said this was a miscommunication and they have been trying to work this out with Corporate and have them retrain the call center staff to clarify that multiple individuals can use the pass, but on different days. This type of misleading language on the website and direction from the call center staff gives off the impression that they are trying to bait customers into purchasing the larger packages upfront and then when they come in, tell them they can only use one each day! I ended up having them cancel and refunding my pass, and then having to pay full price for the day. Not sure I will be back to this establishment given the way they try to find loopholes to lure unsuspecting customers in. read more

Kids had a lot of fun, ran around and were able to get on all the slides multiple times. They have different time slots, 1hr 30min or 2hrs For $6 extra it's better to do the 2hrs unless the kids get tired easy. The staff was nice. Looks clean and overall it's a really fun place. read more

This place is chaos but fun chaos. The kids enjoyed it immensely. They had a blast. There are employees all over the place making sure everyone is safe. There was never a shortage of the mats for sliding. There's TONS of places for parents to sit. There are plenty of charging ports so bring your chargers when you come. They don't allow outside food but there is a typical food service counter with snacks and drinks. There are areas for younger kids as well so for those with toddlers, you can enjoy this place too without worrying about big kids toppling them over. It's a great place to let your kids burn some calories and get their energy out. read more

New place in town at the Ontario mills mall. Located on the north side of mall between Q and Market broiler. Parking can be a bit of a hassle during the weekend rush but valet parking also available if you don't want to search for a spot. Upon visiting we received a warm welcome from staff who were very overwhelmed from the line of guests. It was super crowded but the whole fam had a great time running up all those many stairs to ride the slides. Adults and kids pricing menu pay upon entry. Seating areas and lockers available. Anyone who enters facility will need to sign a waiver then you'll receive wristband. Purchase socks along with general admission or annual pass. Food items available but if you don't wanna wait so long there's plenty of food and drink options nearby. Great location for a change of pace entertainment. read more

So when I walked in I noticed there was no trash and the place was pretty clean. I just got a ICEE I didn't get any food. The slides were pretty fun and I recommend this place for people of all ages. The workers were pretty friendly here and they were nice and they helped me when I got lost in the slide park. Shoutout to Christopher who I made a friend with today. Overall I rate this place 5 stars!! read more

First of all, the staff was extremely sweet and helpful when it came to my special-needs daughter and the questions that I had. It was a very clean place and though it was busy, my son and I were able to slide every single slide before our 90 minutes was up! Some multiple times. It was nice and cool inside too. I felt as though it was worth the money! Snack bar was a little bit expensive but that's to be expected at a play place , especially one in the mall. Overall the staff especially made it a 10/10 experience and we will be back. Thank you again to the sweet brunette manager working today (Sat July 18 around 1pm) who was so helpful to us. read more

We went right when it opened at 11am and I think that was ideal. We paid online for passes + their proprietary socks and filled out the waivers ahead of time so it was checking in and getting straight to playing. It wasn't crowded or chaotic. We did our 90 minutes and then explored Ontario Mills for a while-- when we walked back around 2 pm Slick City was INSANE. Tons of people, crazy loud, and overall a level of chaos that would've ruined my first experience. So come early if you're like me. There's a lot of variety in the types of slides, though it seems like there isn't a good middle ground for thrill seekers. Most of the slides are regular playground slide "intensity" but novel in the ways that you might end up in a sort of lazy half pipe, get spun around by a banking curve, or fall through the slide version of a toilet bowl. Ha. They're fun and pretty tame. Then there are three DRASTICALLY more intense slides: 2 very steep green slides that enthusiastically yeet you into an inflatable crash pad, with enough hang time that they had to put signs up prohibiting doing full-on*flips* at the end. These were just the right amount of thrill for me! Then there's 1 single rider blue slide that I can't believe is just in among the normal ones lol. The first part is essentially a free fall. As in, I wasn't even touching the slide, just falling face first toward the eventual sloping bit of the slide, at which point I made contact and got the air huffed out of me before my lower body banged against it. I decided there was a good chance of me scorpioning myself if I did that slide anymore and made a retreat to a less spicy slide (once my fight or flight instinct calmed down lol). There's a snack bar with the kinds of foods you'd expect. If you're thirsty there are fountain drinks, bottled drinks like Gatorade and Celsius. Thumbs down that there's no drinking fountain or water bottle filler. They have bottled water for $4 or you can ask for a cup of tap water for freeeeeee. But I had to wait 10 mins in line to ask for that free cup... So a water bottle filler would be a considerate move for families, even if it wouldn't make them more money. You hear that, management?! :-) Overall it was a fun way to spend an hour and half. The staff were nice and it felt pretty clean. With the price of admission, it will only be a special occasion thing though. The price and the lack of easy water access makes it overall 4 stars, but we had a great time. read more

Pros: Good place for the kids to unwind, sweat, be active, and have fun. Cons: Seems disorganized, could increase safety, the whole wrist band time limit sucks. My family and I visited slick city here for the first time and it was just ok. Probably will be the last time. 42 dollars a person to slide for 90ish minutes and I say 90ish loosely because the ride attendants tried stopping my kids from sliding a little less than an hour in, but we complained. We went for my daughter's best friend's birthday party and while the event area was decent, the food was horrible. Pizzas at 20 dollars each, no flavor, thin, and they just look sad! One of the people in our group bought a bag of cotton candy at 5 bucks which is ridiculous in itself! The slides were good, just very congested with people cutting on the weekends. We have passed by during the week and wanted to go in but the price remains the same...no weekly discounts after a certain time, no sock fee waived...nothing. They can do a lot better. read more

Slick City was fun, and the slides were exciting at first. The place was clean, and the staff were nice. However, after about 30 minutes, it started to feel repetitive, and there was not much else to do. It was a good experience, but I expected more activities to keep me entertained longer. Overall, it was okay and worth trying once, but I don't think I would stay for several hours. read more

I wanted to share our experience after visiting Slick City with a group of five energetic boys, ages 6 to 11. It was an absolute hit! The place is packed with more slides than you could ever imagine, offering endless excitement for the kids. Even though the venue was buzzing with activity, the wide variety of attractions meant that the lines stayed short, so everyone got to enjoy everything without much waiting. The boys threw themselves into every slide--some were thrillingly fast, others were slow and steady, a few sent them soaring through the air, and there were even slides where they could race each other. Beyond the slides, they also got to play dodgeball and basketball, which were both organized and lively thanks to attentive employees refereeing the games. This added structure kept things fun and fair for everyone involved. For the younger ones, there's a dedicated area with climbing spots and slides tailored for smaller kids, ensuring that everyone has something they can enjoy. And with the heat wave we've been experiencing, the air conditioning was a lifesaver, keeping the space comfortable for both the kids and those of us just spectating. Honestly, I highly recommend Slick City over the usual trampoline parks the kids have visited so many times before. If you're looking for a fresh, exciting outing, this place is definitely worth checking out. Take your crew there for a memorable new adventure! read more

Today was our first time here and will be our last. DO NOT order food here!! I was finishing up helping my toddler use the toilet and heard the urinal flush. I opened the stall door and saw a male employee walked out without washing his hands. I didn't get a good look at who it was but brought it up to one of the supervisors. I was not ready for her reply when she said that they just had a meeting regarding this issue. I guess this was not the first time someone had mentioned of employees not washing their hands after using the restroom. Absolutely disgusting! read more

I was happy with the staff; everyone is very friendly, even the manager. The staff was constantly cleaning, taking trash out and the bathroom was very clean with the amount of people that showed up. I was very surprised how presentable took this place was. I did notice that it wasn't as busy as I expected, especially with the grand opening. One thing I noticed is that there was no promotions or discounts available to the public. I would recommend this place for the amount of FUN we had, but for the price amount some of it would be hard for it to be affordable to other people so having a discount or promotion would bring attention to people and attract more customers. read more

So, from a kid POV, this place was AMAZING. So many fun and different slides and the lines were not bad and went fairly quickly. There is a dedicated are just for the smaller kids, which was nice. My kid and his buddies could have stayed for another two hours had I let them, but we needed to go and my head was aching from the noise level. We pre-bought our tickets for a 315pm reservation. We ended up waiting in line for another 30 minutes before actually getting in. They also did not have the variety of sock sizes for my little guy. He ended up with socks way too small for his feet, and the next size up would have made him trip. The kiddos wanted snacks/drinks, and that also ended up being a huge chore. There were only three ppl ahead of me, but it took about 20 minutes to take and fill orders. What the heck?!?!?! Bathrooms needed to be serviced more often. I get it-kids miss the toilet all the time, but sheesh-- towels and soap dispensers were empty. Kids were coming and going in those socks. Feet were bound to get wet. Ppl were hoarding mats. It was to be expected, and no one was enforcing the timed exits. Paid for two hours, stayed for three. That's on them for not enforcing their rules. read more

Today I was at Slick City and as usual whenever I bring my kids I'm greeted by one of the leads, her name is Bella and she is just such a wonderful person, super sweet and welcoming. I would like to add, she has done so much hard work for us to make our experience great! She's an amazing worker and definitely deserves a raise. Very sweet with kids and attentive with those who need help. read more

I had a very disappointing and stressful experience at Slick City Action Park. I visited with my children to let them enjoy the park and initially purchased tickets without any issues. Shortly after completing the transaction and helping my children get ready for the slides, I received a notification from my bank showing a second charge from Slick City that I did not authorize. I immediately went back to the cashier to ask for help and requested that management review cameras or investigate how the second transaction happened. At first I was told loss prevention was not there, and later I was told there were no cameras. As a parent, hearing that there may not be security cameras in a children's entertainment establishment with multiple exits was extremely concerning. When the manager, Victor, came to speak with me, I felt dismissed instead of helped. Rather than focusing on the unauthorized charge itself, the conversation became centered around defending the cashier. I repeatedly explained that I personally inserted my card for the first transaction and that my issue was the second unauthorized charge that appeared afterward. I asked if there was anything they could do to help, including a refund or proper incident report, and I was denied assistance. The written statement they prepared did not accurately reflect what I reported, so I refused to sign it. What upset me most was that after trying to calmly advocate for myself while also supervising my children, mall security was eventually called and I was asked to leave for allegedly "causing a disturbance." I was emotional and firm because I was distressed about my money and concerned about safety, but I was not threatening anyone or behaving aggressively. No customer should feel dismissed or removed simply for reporting an unauthorized charge and asking questions. I came there to create a fun experience for my children, and instead left feeling embarrassed, unsupported, and frustrated. read more

I did a trial run at Slick City before my daughter's birthday party there and honestly it completely changed my mind. I canceled the booking immediately afterwards. Instead of focusing on safety or making kids feel welcome, they seemed obsessed with enforcing sock purchases every two seconds. I was only accompanying my daughter up the extremely steep stairs, yet staff kept following us around repeatedly reminding me about their special socks like it was the most important thing in the building. If they had mentioned it once, fine -- next time I would've bought them. But the constant harassment was ridiculous. Meanwhile, kids are climbing dangerously steep stairs and could easily trip or fall, yet their priority seemed to be selling socks instead of creating a safe and enjoyable experience. And reminder if you do go , they don't accept other indoor playgrounds grip socks !!! The whole atmosphere felt more money-hungry than family-friendly. Definitely not the fun birthday experience I expected. read more

This place so fresh and new was absolutely sliderriffic! Walk in today 10am greeted very warmly. Sign the waiver pay for my son, this is a pay by minutes place and because it's going to be popular I respect that. you have to buy their socks but you get to keep them and spectators are free. 17 slides, so much to do, thrills for all ages even the little thrill seekers have their own space to explore. Very kind workers, excellent management. Big snack bar, lots of seating and MASSAGE CHAIRS. read more

Sorry to write this review but I wouldn't recommend having a party here. When we first came to inquire about having the party, we were told that we can choose whatever table as long as its not taken and we can adjust how many people will arrive as long as we let them know in advance. We then book our event for 10 because we were not sure if everyone will come and we dont want to pay for those who are not there. 2 days before the party, I notified the person in charge via text that we will be having 15 people. They also have an electronic rsvp where they can alredy see whose coming and minors. I told them that I will only pay for the participants which are the kids. With all these info provided to them. They didnt say anything abt adjusting the # of people in our booking or anything like that. So when we arrive, it delayed our check in because the person incharge of the party was nowhere to be found. The workers there dont know what to do abt the party. It took us a long time to check in bec on their end, there were only 10 reservations. Then I have to pay regular amount for those extra children coming even I told them there will be 15. Then when its time for cake, she is nowhere to be found again, as usual, so wasted more play time. No utensils provided, no water pitcher ( which is supposed to be included) If its time for cake, everything should be ready and you should be there!!! We ended up cutting our own cake , parents have nowhere to sit unless you pay for additional $$. Party person needs improvement. read more

We had such a great experience here taking my niece and nephew! The place was clean, fun, and perfect for kids to burn energy safely.

Definitely coming back! read more

It's a fun experience. I planned to have my daughter's 5th birthday here. Went to try it out, Spent $50 bucks to get her, 1 person in. It was a decent time until all the employees on the floor started to say you needed slick city specific socks to accompany my daughter. Didn't make sense. Employees wearing shoes on the slides but parents had to buy socks? It's strictly a money play and it's really annoying when you are just trying to help your daughter up the steps on the slides. But it saved me over $2000 so that's good. If you go make sure everyone has slick city specific socks on only. read more

Fun for my child but that's where the pros end. Where do I start? time limits for the price is outrageous. On top of that, they require the kids to buy their socks? ridiculous!! my kid came wearing grip socks and staff kicked her off the slide because she wasn't wearing their socks? Lame! I asked for a manager to explain why it had to be their socks and got no viable answer other than "because we require it" preposterous! It's bad enough everything is already expensive, but then nickel and dime parents for socks too??? I was outraged. Parents: take your kid to Bigair instead! it's $20 for unlimited time frame and you can have your kids bring in grip socks they already have if they have them. Will NOT return to this place! read more

Megan the manager is a real MVP. Excellent manger! Very happy with how she handled a little issue we had. Thanks Megan!
