Six Flags Packing List: Don’t Overdo It (Pack Light)

Here’s the thing nobody tells you about packing for Six Flags: half of what you carry in, you’ll spend the day cramming into a locker so you can ride a roller coaster. Modern coasters won’t let you keep your phone, your keys, or your dignity in the queue. So the real question isn’t “what should I bring to Six Flags?” — it’s “what’s the least I can get away with?”

I’ve done the Six Flags day with a husband, a stroller, and kids who treat a souvenir cup like a trophy. Whether you’re heading to Great Adventure in New Jersey, Magic Mountain in California, or Great America up in Gurnee, Illinois (the park in all these photos), the packing logic is the same. Bring what earns its spot in a locker, and leave the rest in the hotel room.

The Quick Verdict: Pack Light, Lock the Rest

If you read nothing else: bring a small day bag with payment, sunscreen, a refillable water bottle, and a portable charger — and accept that you’ll pay for a locker on the big coasters. Most Six Flags parks now ban loose articles (phones, keys, hats, glasses, bags) in the queues of major thrill rides. You either hand your stuff to a non-rider or rent a locker, and the lockers cost money. That single rule is the whole reason this packing list exists: every extra thing you carry is one more thing you have to stash or lose.

What Should You Pack for Six Flags?

Pack for two different things: the trip (hotel nights, getting there) and the park day itself (the small bag you actually carry around). The full list below covers the trip; the “Theme Park Day Bag” section near the bottom is the short version you’ll live out of inside the gates. Most of this is evergreen — clothes and toiletries don’t change. What has changed is Six Flags itself, which I’ll get to.

Six Flags Packing List

Clothes

Pro tip: Check the forecast before you pack a single shirt. A Six Flags day is long, mostly outdoors, and water rides will soak you whether you planned on it or not. Closed-toe shoes you can run in beat anything cute — you’ll walk for miles and some coaster queues won’t let you ride in sandals.

What you pack depends on the season and the forecast. Pull weather-appropriate items from this list:

• Shorts
• T-shirts
• Long-sleeved shirts
• Pajamas
• Socks
• Gym shoes – Closed-toe and broken in. This is not the trip for new sneakers.
• Sandals or flip-flops – Perfect for the water park or giving your feet a break at the hotel
• Bras
• Underwear
• Swimwear – Two per person. Hang wet suits in the bathroom and rotate.
• Pants
• A jacket – Even in summer, an evening after a soaking can turn chilly.

Pro tip #2: For longer trips, pack laundry pods and do a load mid-trip. You’ll cut your luggage in half and have dry clothes every day — which matters more than usual when half your wardrobe keeps getting wet. We use the same trick in our minimalist Disney packing list and it has never once failed us.

Quick note for the photo above: at Six Flags Great America this flume rode for decades as the Yankee Clipper. It was re-themed to Aquaman Splashdown in 2022 as part of the Metropolis Plaza / DC area. Same splash, new name — so if you go looking for it on the map, that’s what to search for.

Accessories to Bring to Six Flags

• Ponchos – Cheaper than the souvenir-stand ones and a lifesaver on rapids rides.
• Sunglasses – With a strap, or be ready to take them off for every coaster.
• Hats
• Hair ties
• Goggles – For the water park.
• Floaties or lifejackets – Most water parks provide free life vests, so check before you haul your own.

Baby Items

Babies require a lot of gear, but you don’t need to overpack. Many items are available at hotels, and you can buy basics like diapers and formula near the park rather than flying them in. When in doubt, call the hotel ahead to confirm what’s available. For the bigger picture on traveling with little ones, our eight tips for traveling with kids cover what actually matters.

• Formula and baby food – Pack enough for the trip, or plan a grocery run on arrival.
• Bibs
• Pacifiers – Bring extras; they have a way of disappearing the second you need one.
• Sippy cups
• Bottles
• Diapers – Both regular and swim (but not more than you need).
• Wipes
• Stroller – Strollers are allowed in most parks; double-check policies and where to park it before water rides.
• Car seat Unless offered by your ground transportation provider.
• Breast pump and accessories
• Dish soap and bottle washer

Toiletries and Bathroom Essentials

Pro tip: Grab a set of travel bottles so you can bring your own products in carry-on sizes instead of buying overpriced minis on the road.

• Toothbrush
• Toothpaste
• Mouthwash
• Floss
• Hairbrush
• Hair styling products
• Glasses – A strap is smart, since you can’t wear loose glasses on most big coasters.
• Contact solution and extra contacts
• Face wash
• Makeup
• Deodorant
• Sunscreen – The single most-forgotten item, and a sunburn ruins day two.
• Razors
• Shampoo – You only need this if the hotel does not provide it or you need a special kind. Tear-free is probably not at the hotel.
• Conditioner – Same criteria as the shampoo.
• Body wash – If the hotel doesn’t provide it.
• Loofah
• Cotton swabs
• Tissue
• Tweezers
• Laundry detergent pods
• Feminine hygiene products
• Lotion – If you need a specific kind and the hotel doesn’t provide it.

Medications and First Aid

If your kid (or you) gets queasy on spinning rides, motion sickness medicine is the difference between a great day and a sad bench. Pack it whether or not you think you’ll need it — coasters have a way of finding everyone’s limit.

• Medications
• Medical equipment
• Vitamins
• Motion sickness medicine – Non-drowsy, so nobody naps through the day.
• Pain relievers – For both adults and children.
• Thermometer
• BAND-AIDs – Blisters from a full day of walking are practically guaranteed.
• Antibacterial cream

Important Documentation

Digital versions are fine for most of this — just make sure you can actually open them on your phone without signal, since cell service inside a packed park can be spotty. Screenshot your tickets and confirmations before you leave the hotel Wi-Fi.

• Park tickets
• Airline reservation confirmations and boarding passes
• Hotel reservation confirmations
• Rental car and ground transportation reservation confirmations
• Identification for all travelers
• Priority Pass card
• Health insurance card
• Proof of car insurance

How Do You Pay (and Stash Your Stuff) at Six Flags?

Two things to know before you go, because they shape what you carry. First, most Six Flags parks are now cashless — bring a card or your phone’s wallet and leave the wad of bills at home. Second, the loose-article rule on big coasters means you’ll either hand your bag to a non-rider or rent a locker, and the lockers carry a fee. Entrance lockers and single-use ride lockers are common, and at some parks a paid locker is mandatory at certain coasters. Plan for a few dollars here and there, and don’t bring anything you’d cry over losing.

One more money note: Six Flags sells a refillable souvenir drink bottle for the season (recently around $39 at Great America) that gets you cheap fountain refills. You can usually still bring an empty personal water bottle through the gate and fill it at a fountain for free — confirm the current policy on your park’s page, since outside-food-and-drink rules vary by location.

Miscellaneous

What to Add to Your Six Flags Checklist

• Travel entertainment – For the drive or downtime, not the ride lines.
• Snacks
• Refillable water bottle – Hydration on a hot coaster day is non-negotiable.
• Cell phones and chargers
• Portable cell phone charger – Mobile ordering, ride apps, and photos drain a battery by noon.
• Cooling towels – Only if it’s really hot. Check the weather.
• Noise-canceling headphones – Only if loud noises freak your kid out.
• Gum
• Refillable drinks and popcorn buckets – If applicable.

Theme Park Day Bag

Can you bring a backpack on Six Flags rides? On most major coasters, no. Bags, phones, keys, hats, and glasses aren’t allowed in the queue — you’ll either leave your bag with a non-rider or rent a locker, and the lockers cost money. So keep your day bag small, skip the valuables, and pack it knowing half of it is going in a locker. Big backpacks, hard coolers, and suitcases are generally banned at the gate anyway, and bags get screened on the way in.

• Methods of payment – A card or phone wallet, since most parks are cashless.
• Identification
• Theme park tickets
• Cell phone and portable cell phone charger
• Jackets – Only if needed.
• Ponchos
• Sunscreen
• Motion sickness medication
• Pain relievers
• Hats
• Sunglasses
• Cooling towels – Only if needed.
• Tissue
• Feminine hygiene products
• BAND-AIDs
• Refillable water bottle
• Baby stuff you need on a typical day
• Gum
• Hand sanitizer
• Chapstick
• Refillable drink and popcorn buckets – If applicable.

Six Flags Water Park Packing List

Remember that you’ll have to set this bag down to ride the water slides, so the same locker rules apply — Six Flags water parks have lockers, but they charge a fee. Use a waterproof phone case or a locker for anything electronic, and don’t carry valuables you can’t afford to lose to a wave pool.

• Cell phone and portable cell phone charger
• Sunscreen – Water-resistant, and reapply more than you think you need to.
• Hats
• Sunglasses
• Hand Sanitizer
• Tissue
• Feminine hygiene products
• Gum
• Chapstick
• Pain relievers
• BAND-AIDs
• Waterproof cell phone case – If necessary.
• Baby stuff you need on a typical day

Has Anything Changed at Six Flags Lately?

Yes — and a couple of changes are worth knowing before you plan, so you’re not packing for a 2019 version of the park. Cedar Fair and Six Flags merged in mid-2024 into a single company, Six Flags Entertainment Corporation, running roughly 42 parks across the US, Canada, and Mexico. Your local park keeps its name and characters, but a few back-end things have shifted.

• Line-skipping changed names. The old THE FLASH Pass was retired in early 2026 and replaced company-wide by Fast Lane (with reserve, priority, and ultimate tiers). If you’re buying a skip-the-line upgrade, that’s the one to look for now.
• Two parks are winding down. Six Flags America in Maryland closed for good after the 2025 season, and California’s Great America in Santa Clara is slated to close in the next few years. So don’t assume every legacy park you remember is still open — double-check before you book a trip around one.
• Great America (Illinois) is thriving. The Gurnee park in these photos is celebrating its 50th anniversary in 2026 and added a new dive coaster, Wrath of Rakshasa, in 2025. None of this changes your packing list — but it’s a good “new since you last went” hook if it’s been a while.

Six Flags Packing FAQ

Can you bring a bag into Six Flags?

You can carry a small bag around the park, and bags are screened at security on the way in. Large backpacks, hard coolers, and suitcases are generally not allowed. The catch is that you can’t take a bag (or your phone, keys, hats, or glasses) into the queue of most major coasters — you’ll stash it with a non-rider or in a paid locker. Keep the bag small.

Do you have to pay for lockers at Six Flags?

Yes. Lockers carry a fee, whether it’s a day locker near the entrance or a single-use locker by a ride, and some parks make a paid locker mandatory at certain coasters. Exact prices vary by park and locker type, so budget a few dollars and check your specific park’s page for current rates.

Can you bring your own water bottle into Six Flags?

In most cases you can bring an empty personal water bottle and fill it at a fountain or refill station — a smart move on a hot day. Outside-food-and-drink rules vary by park, so confirm on your park’s policy page. Six Flags also sells a paid souvenir refill bottle (recently about $39 at Great America) if you’d rather have unlimited fountain refills.

What should you wear to Six Flags?

Comfortable, weather-appropriate clothes and closed-toe shoes you can walk miles in. Secure anything that can fly off — sunglasses on a strap, hats you can stuff in a pocket, no loose jewelry. If water rides are on the agenda, wear or pack a swimsuit and expect to get wet whether you planned to or not.

Is Six Flags cashless?

Most Six Flags parks are cashless now, so bring a card or your phone’s wallet. If all you have is cash, parks typically offer a kiosk that converts it to a prepaid card — but it’s easier to just plan on plastic.

Final Thoughts – Six Flags Packing List

Six Flags is about thrills, not amenities, and the whole day is built around stashing your stuff so you can ride. You genuinely don’t need much — bring what earns a spot in a locker and leave the rest in the hotel. Pack the small day bag, expect to pay for a locker on the big coasters, and you’ll spend your day on the rides instead of guarding a backpack.
