The idea of yelp is to provide honesty and transparency. Save your money, gas and time! I drove from Corona to take my son here after I purchased a Groupon to use. As soon as we walked in, there was a rancid smell and you can tell the place is not cleaned. You're quickly reminded you're in San Bernardino. The staff is incompetent. I'm was told they couldn't honor my Groupon and offered no further assistance other than giving me full pricing. I said it was unacceptable and bad business. Never will be going back. We walked out and left. I'm not going to support a place like this. Go to the competitor.

Experience: 4/5｜Service: 4/5｜Facility: 4.5/5…read more We booked our session through Groupon, which helped save a bit compared to regular pricing. Even with a reservation, it was quite busy the day we went, so there was still a check-in process to go through at the front. That said, everything was organized and moved along reasonably well considering the crowd. I've been to another K1 Speed location before, and this one definitely feels newer and cleaner. The facility is well-maintained, and the helmets were in good condition with no unpleasant odors -- something I really appreciated. The overall environment felt safe and modern. We brought a child with us and asked if it was possible to group them with other kids. The staff was very accommodating and explained the different kart ranges available for younger drivers. They made sure everything was age-appropriate while still keeping the experience fun. As for the track itself, it was exciting and well-designed. The karts were responsive, and the layout had enough turns and straightaways to keep things engaging without feeling overwhelming. Overall, a fun and energetic experience -- especially great for families -- and I'd definitely consider coming back again.

Imagine an experience so bad you finally download the yelp app…read more.. The food experience minus 1 star. Waiting 30 minutes for a pretzel and onion rings sucks, it especially sucks when the onion rings taste horrible and look just as bad. Its even worse that you ordered prior to a party arriving and yet they got at least two orders of wings and pizzas delivered before your food even hit the table. Install a notification system, minus 1 star. Waiting an hour and a half to ride is fine. Not being able to leave is the problem. Its 2026 and you can't have a push notification system for guest....maybe its better with a reservation but living over an hour away and with California's traffic its not something that can be guaranteed for some. It wouldn't be fair to not review the actual thing people come here for. The racing is fun and exciting. Course is done well. Plus 1 star.

Jacob and Santiago you guys rock! Came here for a birthday party and the service he provided was…read moreamazing! Jacob handled a whole party by himself and he was so patient. Not that there was any issues, but it can be overwhelming On the other hand, there was an unruly father who would not take no for an answer. Santiago had to get the manager and security because some dad was arguing with the poor employee about not letting his son go on a ride because he was too short. The manager came with security two separate times and he still would not listen. Thanks Bullwinkles , thank you for keeping us safe!

My wife, son and I recently visited Bullwinkle's in Upland for the first time and our experience…read morewasn't that great. We had taken our son to go use the batting cages and when we got to the counter there wasn't anyone to assist us with getting a bat or hat. We waited a good 10 minutes and when we noticed the person who was supposed to help us was out there batting while he was working. I had to go to the front counter to go complain because it wasn't fair for us to be waiting so long. Another thing that we didn't like was if you have Schools first debit card for some reason they couldn't take it. The good thing was we had cash with us, but if we didn't we were going to be screwed. All I got to say is they have to work better with customer service.

What an amazing place! They have a little bit of everything and although I can understand how it…read morecan get pricey, compared to K1 speed I prefer here so much more. There's laser tag, bowling, arcades and axe throwing which is helpful for wait in between races. Cameron and Rychie have always been so kind, welcoming and fun to coordinate with. All the gals are sweet too. I bring my son here often, and because of their welcoming spirit I always come back with more kids.

Visited Alpine Slide at Magic Mountain and did the coaster such a blast! It goes surprisingly fast,…read morebut you're in full control of the brakes, which makes it exciting and fun. The views going up and down are absolutely beautiful, so you really get to enjoy the scenery while riding. They also have several other activities to do, which is great if you're spending the day there. Just note there isn't a bundle for all rides it's pay-as-you-go for each activity. Overall, a super fun experience and definitely worth checking out if you're in the area.

The alpine slide and the mineshaft coaster were both so much fun!…read more The older lady in the ticketing booth for the coaster was kind of rude. When I was paying for my ticket, I also mentioned that I wanted to pay for the video. I obviously am unaware of how things are. I did t know that you would pay for the video after the ride. She just said something so condescending and rude. A little explanation of how I can preview the video, then pay for it after the die was done would have been nice. I didn't appreciate her at all. She was the elderly woman working the ticket booth around noon on Saturday, June 6, 2026. She might need to be retrained on how to give customer service.

What an amazing place. It's like going back in time. Kyle was cool about answering 1000 questions…read more I had the day before we went and was equally helpful helping out for our day at the track. Troy is the other man to know over there. Such a good dude. Also patiently answered several of my questions and helped me get my old Kart, safe and ready for the track. New tires, a new gas tank fuel lines. They had everything in stock and bolted it on like a pit crew. The track is fantastic and the perfect size for Go Kart. They also have motorcycles out there. Super fun to watch. I feel like it would be a pretty tight circuit on a quick motorcycle. They sell cold drinks, chocolate bars, and chips... All the health food required to survive a day on the track. I ended up leaving my Go Kart there for around $100 a month. They'll start it for you and pull it out with a days notice when you want to go racing. Racing and convenient are usually two words that don't live in the same sentence but you'll find that at this place. Do yourself a favor and check them out.

Final Regional FAT Race of 2025. Don't waste your time or money with FAT racing league. Really kind…read moreof a joke, and it's the same people that win over and over. They penalize the new kids and dont fix the carts when crashed. Organization sucks, people that run it are clueless, and nobody can answer a question you want one answered. It's always a different answer every time you ask it to multiple people. Adam Park is ok. They gotta make their money one way so they charge $20 a person to get in. Really kind of sad considering Willow Springs is way better and they don't charge you anything. Also, the cell service here Sucks. No wifi and the ports potty's bathrooms are terrible and haven't been emptied in quite a while. No food anywhere close and Uber eats doesn't come. With all the Roach coaches in the greater Riverside area, we can't get one or two to come here for racing season? Or how about a Coca-Cola vending machine?

It's been years since I've been to Boomers, but I went with my family and it was alot of fun. We…read morecame primarily for the mini golf course and we had a great time. I was surprised to see that they actually have two different 18 hole courses! We all got the 2 hour unlimited package, and we did alot actually during our time there. We did two 18 hole mini golf courses, I did a little rock climbing on the rock wall, and played a couple arcade games. I felt like the arcade didn't have many games. I was a little bummed to see that. It is a small space which I understand, but it would've been cool to have more variety and options. I like those Dance Dance Revolution games, I don't think I saw one like that there. It would be nice if the arcade was updated and had more games inside. Every employee we were interacted was great. They were friendly, helpful, and got to us as quick as they could. It's just that when we were trying to pay and get our golf clubs, there wasn't anyone at the desk and it seemed like the one employee had to help with the prize desk. And of course, there was a kid who was taking a while to pick a prize so we had a line behind us. It's not anyone's fault but I think they just lack staff. I would absolutely come again for the mini golf haha, it was a fun time.

The automatic doors parted before me like the gates to a forbidden arena. My heart pounded--not…read morefrom fear, but from anticipation. The smell hit me first: burning rubber mixed with ozone, a bouquet that spoke of countless battles fought on these very tracks. I approached the counter, signed the waiver with trembling hands. This was it. My initiation into the world of electric velocity. The safety briefing washed over me. Speed limits. Racing lines. Flags. But my mind was already elsewhere, imagining the perfect lap, the flawless execution of every turn. Then I saw it: the kart. Sleek. Silent. Deadly. I lowered myself into the molded seat, gripped the steering wheel. The moment my foot touched the accelerator, everything changed. The instant torque slammed me back into my seat! No engine roar, no warming up--just pure, unadulterated acceleration that felt like being shot from a cannon! The first corner approached rapidly. I braked--perhaps too hard--and felt the rear end slide ever so slightly. My pupils dilated. This was it. This was the dance. Turn two. I remembered the instructor's words. Brake early. Apex late. Accelerate through. My body moved on instinct, finding the rhythm, becoming one with the machine. By lap three, everything crystallized. The track revealed its secrets to me. That slight banking in corner four. The deceptive tightness of the chicane. Each revelation was a flavor explosion on my palate--bitter defeat transformed into sweet victory! Other racers surrounded me. I could feel their presence, their fighting spirit! We weaved through corners in formation, each seeking that perfect line, that extra tenth of a second. When I finally executed a flawless outside pass on the long straight, my entire body surged with electricity! The laps blurred together in a symphony of speed. Left, right, brake, accelerate--a recipe perfected through repetition, each iteration bringing me closer to nirvana. And then, too soon, the checkered flag. My final time flashed on the screen. I stumbled from the kart, legs shaking, heart racing, a massive grin splitting my face. The other racers gathered around the timing board, comparing battle scars and bragging rights. This wasn't just fun. This was transcendent. This was speed distilled to its purest essence, served at precisely the right temperature to ignite the soul! K1 Speed had delivered a five-star experience that left me hungry for more.​​​​​​​​​​​​​​​​

I gave this location (2) stars for the staff when you come in to register (they were helpful and…read morewelcoming) and because of my food (which took a while to order because the girl who took our orders seemed like she was not all there --for lack of better words-- she made the ordering process longer and difficult than it needed to be). The biggest issue was a staff around the track --this (1) girl in particular appeared to be having too much fun slowing certain go-karts down with her red remote, imo. But I'll get back to that in a sec. We decided to eat first: Food was okay-- ordered pepperoni pizza (they almost left it in too long and some of the crust was burnt. Had to break those pieces off and eat around it) and Pepsi in a bottle. My bro got sliders, wings, tots and Pepsi. His food took a while so we couldn't really eat together. Ended up sharing my food while we waited for his to come out -- which was weird since we were the only ones there who had ordered anything. When his food finally arrived he ate some of it and threw the rest away --guess he wasn't impressed. He mentioned it was "decent". Now to the races: Multiple people came and bumped me trying to get past me --never saw her slow their go-carts down but she definitely slowed down me and my bro multiple times when we were the ones getting bumped continuously. It got to the point where I just purposely stayed the last racer just to try and enjoy the experience and made no attempts to move up the ranks. Idk what the men's restroom looked like but the women's restroom had lots of gnats! Paper towels overflowing from the discard. Important to note: For as many staff as they had lollygaging around near the track you would think the place would be spotless. There weren't a whole lot of customer so definitely some staff could've been putting in some time and effort to clean around the place. Ultimately: We paid for (3) races. Ended up only using (2) mutually agreeing it was time to get outta there. Leaving the 3rd race on our accounts for another visit that we will be using at ANOTHER LOCATION. No I don't recommend and doubt I'd be returning. This review is reflective of my visit on 11/7/25 Duration of stay around 2hrs.
