    I don't know if it's only me. But Six Flags is not how it used to be years ago. Seems like you seen more friendly and happier staff, these days they just have the look on their face like "ughh another day". Food selection here is not so great, but you eat anyways because you're hungry.

    I don't usually leave reviews like this, but people should know what they're walking into with Six Flags. This place is honestly the armpit of amusement parks. From the moment you walk in, it feels run-down and neglected. Nothing feels updated, clean, or well-maintained. You can tell this park has been left behind while others have evolved. It doesn't have that fun, exciting amusement park energy; it feels tired. The biggest issue? The lines. It honestly doesn't matter whether you pay extra for a fast pass; you're still standing around forever. And what made it even worse was that THREE separate times we waited in line, got close to the front, and then the ride shut down. No real explanation, no urgency to fix it, just wasted time. At that point, you're not even enjoying your day; you're just frustrated and stuck. What really crossed the line for me, though, was the condition of the animals. The fish tanks looked like they hadn't been properly cleaned in years. No real plants, cloudy water, just depressing to look at. It's 2026; there's no excuse for that. It didn't feel like care or respect for the animals at all. That alone made the place feel uncomfortable, and honestly, it shouldn't be allowed. We also ate at JB's Sports Bar & Grill, and that was another disappointment. The food was overpriced, low-quality, and tasted terrible. The ordering process was completely disorganized, with long waits, confusion, and staff who seemed overwhelmed. For what you pay, you expect at least decent food and a smooth experience, and this was neither. The overall vibe of the park just felt off. It attracts a certain kind of crowd, and combined with how run-down everything is, it doesn't feel like a place you want to spend your time or money. Bottom line: I would not recommend this place. Between the constant ride shutdowns, poor upkeep, questionable animal conditions, and bad food, it's just not worth it. This park seriously needs major improvements across the board, or it shouldn't be operating at all.

    If you live in the bay area there are two options for a theme park - Six Flags and Great America. Both are fun and good alternatives to Disneyland. Disneyland got so expensive over the years.... everything got expensive over the years - but still if you live in the bay area you don't have to worry about hotels and long travel costs that come with going to LA. Little kids might enjoy Disneyland more and Great America and Six Flags is more aimed toward young adults. I like this park and have great memories especially as a kid - perfect to go to on a summer vacation for a day trip. Some roller coasters and some animal attractions. Near the highway and easy from San Francisco or similar area.

    Sorry Kya, too short :(

    If you want to truly have a good time, come as soon as they are open! Get on the main rides you want to enjoy or come late & get ready to battle it out with the people that paid for fast passes. Other than that, enjoy.

    Tired And COLD At Six Flags Vallejo, CA Came With My Fiancée And Mt. Toro H.S. Postpone Club. I Had To Come Back And Add A Comment Since The Business Owner Replied; So The Reason I Didn't Emphasize The COLDNESS Enough Was I Just Wasn't Trying To Keep Typing When My Fingers Were FROZEN..!! I Forgot To Mention That The Park Staff We're I'll Prepared For How Truly COLD It Was. NO Warming Stations Finally Later In Evening Staff Were Rolling Out Those Outdoor Heaters Sporadically About The Park. And Finally We Found Some Relief. But Second Thought For Staff.

    I had a great time at Six Flags even though a lot of the reviews I see are negative. Good: - We got the FLASH Premium pass and it was absolutely the right call - we barely waited in line, and when the Batman ride opened at night we got on after about 15 min in line instead of 90 minutes - We went for the Fright Fest as well, and the mazes were well done! I liked the haunted mansion the best, club fear wasn't that great since it was very empty and not as many actors inside. The spooky vibes were great and the actors seemed to have a good time - My favorite rides were the Joker, Batman, and the Wonder Woman Lasso ride, that's definitely the longest ride. Superman was also high thrill. - The park wasn't super busy on a Saturday, and parking was easy as well. Very walkable - Dolphin show had cool tricks, but the talk track is definitely for kids Bad: - Food is really expensive, $20 for basically a single slice of pizza and salad - Gets really hot during the day, but cool during the night so bring layers Overall this was a really great experience and would come again

    It was awesome not too crowded for a Sunday. The food was great and the animals were even better. That was a plus that I didn't even know it was there the dolphin show I recommend. I'm glad we waited. Lines were not crazy long.

    Yikes. This is place is a disaster. Operations are abysmal. Operators are moving at a turtles pace with no enthusiasm. Clearly see many people cutting the lines and not do a single thing. Rides and "themed" areas are rusting and bare bones. Many rides broke down with no remorse from staff. They take their time trying to get it back up with no updates leaving people waiting in the hot sun. The animals look in despair. What was the thought process in putting creatures in small enclosures near screaming children and rollercoasters. I feel so bad for them. The red and white macaws are placed near a playground in which screaming children are running and throwing things. The alligators are placed next to a rollercoaster (Boomerang) that is a rumbling and loud environment. This is clearly not an optimal environment for any animal. It's cruel. I'm quite surprised with the current Six Flags company downsizing their park roster, they didn't think to sell off this dead weight too. I'm sure it wouldn't be too long till this park reaches its inevitable closure. Stay far away!

    Cheap passes but everything has an up charge and the concessions are horribly overpriced (think $11 soft serve or $18 16oz Modelo beer). The lines are slow making it difficult to get in too many rides with the late opening time. This trip I was bummed when the season pass I was given when I entered wasn't valid. I found out when I tried to get my 10% discount on food. I spent at least 1/2 hour in the guest relations line to get the pass error fixed. I was told if I wanted to get refunded the overcharged 10%, I could go back to the restaurant and try to speak to a supervisor. This was a big waste of my time for their error and it wasn't even completely resolved. The butterfly pavilion was a highlight. **sent my review and concerns to customer service as directed in the business response. Will update my review with follow up** Edited to include a pic of the response I received from customer service and a screenshot of gold pass perks. Maybe the food I purchased actually did not qualify for a discount, but I could not find anything in the fine print or FAQs. 10% of my purchase would've been like a $3 refund. I really just wanted to see how the company would handle my issue after the kind response to my review saying to reach out to customer service so they could make it right. Dropped this review down a star from 2 to 1.

    We had an okay time, but honestly, there's a lot that needs work. Let's start with the food--it's giving cafeteria food at gourmet prices. Dry, flavorless, and nothing I'd want to eat again. The burgers at the Grill tasted spoiled and were very dry. The fries were the only thing edible. For $20- i expect so much better. The bathrooms weren't much better. They really need to be cleaned more often, period. Spider webs from the last time I came to the park- in 2024... Do better. It already smells like wet dog, at least clean the toilets, floor and stalls. Now the chaperone policy--either enforce it fully or don't even bother. We saw so many kids, clearly under 16- walking around with no adult in sight. And where was security? We only saw them once or twice, and even then they were just walking past big groups of unaccompanied kids like it was nothing. The bus service? What happened to the ones from last season? The new setup is a mess. Not convenient at all, especially if you're coming in from out of the area. And don't get me started on the season pass/membership options. More expensive now with fewer perks. It feels like we're being charged more for less, and that's not it. They removed tiers from 2024, and for the same price you can only go to one park vs all parks from 2024. I understand they have bought Great America and all Cedar Point parks- why not include those parks in the seasonal price?? Why is everything now an extra charge? To top it off, a bunch of rides were shut down or not running the whole day. That's a big letdown when rides are the whole reason we came. We made the best of it, but they need to get it together if they want folks to keep coming back.

    Went last night for opening of freight fest. This review is for Six Flags in general not Freight Fest because the actors were all really cool , engaging. However there was a major incident in one of the houses I'll let you know later on . So I brought my daughter and her boyfriend and I had them bring hoodies because it was starting to get cold. Right as we got up there we were approached by security and they told us that he needed to remove his hoodie and take back to the car. There was nothing wrong with his hoodie . It was an expensive Bape Hoodie. So we had to rent a locker and leave in locker. The employees were being extremely rude about it . Nowhere on the rules does it say anything about bape hoodies . We definitely were being targeted. We spent a lot of money on season passes and had to buy everyone haunted passes because that is an extra charge. And we drove a long way to get to Six Flags. We shouldn't have to deal with rude staff giving us attitudes. I think it was ridiculous that he couldn't wear his hoodie . Now in 1 of the haunted houses my daughter was wearing her boyfriend's chain & Jesus medallion . When she was inside the haunted house someone grabbed and snatched the medallion off of her. She felt it but couldn't tell who because it was packed with people and dark. When she got out she was all upset and we were trying to find it . Staff said they weren't able to find it. And I had 1 staff member say why would you wear that here. We should be able to wear jewelry to an amusement park. Done so before never had a problem. It was a couple hundred dollars and I had to buy him a new one. This of course ruined our night so we ended up leaving and kids only got to do 2 haunted houses. Waste of gas , time & money!! Very upset!

    My son loves Six Flags amusement parks. We have been to the Valencia, Ca location over a dozen times cause it's close to our house. We also took him to San Antonio last summer and he loved the rides there as well. This weekend we came to San Francisco so we decided to come to this Six Flags. We had a great time. The park is beautiful. So many cool rides that he loved so much. I was a big fan of the butterfly garden. Soooo beautiful. So many colorful beauties flying around. I visited them a few times while at the park. The picnic tables by the lake was also a good spot for me to hang out while waiting for the family to get on rides. Feeding the giraffes is a great idea but I kissed the feeding times. The dolphin show was so cool, we enjoyed it as a family very much. We had an awesome time het and highly recommend it to all. There is something to do for every age group.

    We have not been here for years. Rides are thrilling and fast. The attendants could have moved faster. They did not care till it was closer to closing time. Food was ok, regular amusement park food. The dolphins and sea lions/seals shows were very good. Will come again for these. Parking was plentiful.

Overall I personally would not wait more than 40 mins for this ride, because on days where the park is empty, you could get on in under 20. Something I would recommend is if there's only 2-3 people in your party and the line is super long, just go to the single rider line (on the left side when you enter the ride line) - who cares if you don't get to sit RIGHT next to your friend haha, don't wait an hour plus for this ride. The best thing about this ride is that it's a LONG one - I think it's like almost 3 minutes so it's worth your time, and it's a pretty fun floorless roller coaster that has a lot of twists, turns, and upside down moments. Very snake-like fitting for its name. Super smooth, NOT rough like Kong (the worst ride at this park LOL). Definitely this ranks as top 2 roller coasters in this park for me (the first one being Joker). The only con is it does occasionally have technical difficulties, but they usually get it up and running again in 10-15 minutes. Also has a dippin' dots close by haha.

    It seems like launch coasters are the "it" thing at Six Flags Discovery Kingdom, as this park…read moreboasts of not 1 but TWO launch coasters. Superman is the other one and I personally think that one is better than The Flash, but that does not mean The Flash has no presence in Discovery Kingdom here. The coaster itself looks pretty small as there isn't a lot of track, but that's mainly because it's a launch coaster that goes back and forth. It reminded me a lot like the now defunct Deja Vu in some ways. Outside the loading dock, there are two ways you can go -- one in an ultra-twisted inline curve, and the other that goes straight up 90 degrees. So you're kinda all over the place for this ride, but you're definitely in for a treat. With maximum speeds of 60 mph and going as high as 150 ft, the ride may seem like it's not much but there's truly a lot to offer. There's a lot of surprises while riding this out, so make sure to check this ride out when you're at the park !

    This is a good coaster. I am starting to get nervous because I've seen Wicked Twister close at…read moreCedar Point and this could be next to close. The launch is great and I like the custom slanted twisted spike so everyone gets to go upside down which Six Flags Great America's did not have. I like Steel Venom at Valleyfair more because it has the holding brakes on the vertical back-spike. So this ride I would recommend for kids under the age of 17 would enjoy. But people over the age of 39 probably wouldn't enjoy it because there are some rough patches.
