Carry only a compact daypack, sling, or waist pack; large duffel bags and rolling suitcases may be refused at the gate. All personal bags are subject to inspection on entry. Prohibited items include weapons, alcoholic beverages, illegal substances and glass containers; prescribed medications and infant supplies are permitted but should be declared during screening.

To speed up entry: use a clear bag or small purse, pack liquids in resealable bags, and keep electronics accessible for inspection. Place phone, wallet, keys and essential medication in internal zipped compartments to reduce the chance of loss on rides.

Many thrill rides and animal interaction areas require removal or secure stowage of loose articles. Rent a locker near major attractions for bulky items or leave larger parcels locked in your vehicle. For hydration, choose a bottle that fits an exterior pocket or a collapsible container.

Policies can change; verify the latest restrictions and locker availability on the park’s official website or by contacting Guest Services before your visit.

Are daypacks allowed at the park?

Allowed: small soft-sided daypacks up to 16 x 16 x 8 inches are accepted; every bag is inspected at the security checkpoint. Oversized bags, wheeled suitcases and hard coolers are prohibited and should remain in your vehicle or in a paid rental locker.

Entry rules

Prohibited items typically include weapons, outside alcoholic beverages, illegal substances, drones and glass containers. Empty reusable water bottles and factory-sealed bottled water are usually permitted; expect staff to ask you to empty containers at security if necessary.

Packing recommendations

Use a compact daypack with secure, zippered compartments and a waterproof phone pouch. Store loose items (sunglasses, hats, wallets) in zipped pockets while queuing or on rides; most major attractions require riders to stow loose articles in lockers or hand them to a non-rider. Carry only essentials: ID, credit card, small sunscreen, and any required medication in original packaging.

If you anticipate needing larger gear, reserve a rental locker near the main entrance or at select attractions; fees and availability vary, so check the park’s official site before arrival. Arriving early reduces time in the security line and increases locker availability.

Pack policy at park entry – immediate recommendation

Arrive with a compact soft-sided daypack or small crossbody bag; all bags will be inspected at the gate and oversized luggage or hard coolers are often refused. If carrying medications or medical devices, keep prescriptions or doctor notes handy for verification.

Permitted items (typical, with conditions)

Small purses, clear tote bags and fanny packs; diaper bags and baby food; factory-sealed single-use bottled water and empty refillable bottles; sealed snacks for infants or special dietary needs; noncommercial cameras and smartphones (no large tripods or detachable pro lenses for commercial use); service animals with documentation; small umbrellas and lightweight ponchos.

Prohibited items (common list to avoid bringing)

All weapons and weapon replicas (firearms, knives over pocket size, brass knuckles), illegal drugs and narcotics, alcoholic beverages purchased off-site, fireworks and flammable fuels, propane tanks and portable grills, glass containers, large hard-sided coolers and picnic baskets, drones and remote-controlled aircraft, hoverboards, skateboards and scooters, wagons and folding lawn chairs, selfie sticks/monopods and large camera rigs, laser pointers, aerosol sprays intended for self-defense (pepper spray) that are restricted by park policy, unauthorized commercial vending equipment, non-service pets.

Security procedure: every bag will be searched; prohibited items must be surrendered, returned to your vehicle, or disposed of. Short-term storage or lockers may be available near the entrance; Guest Relations may offer limited assistance at the gate. Best practice: leave nonessential or restricted items in your car, use a clear bag or small waist pack, and label prescription medications.

Maximum permitted bag dimensions under park policy

Maximum allowed size at the gate: 16″ (H) × 12″ (W) × 6″ (D) – metric: 40 × 30 × 15 cm. Dimensions cover straps, external pockets, and any protruding hardware; items larger than this must be stored in a locker or left in your vehicle.

Measure the bag at its fullest points: height from base to highest point (include rolled closures or extended straps), width across the front panel, and depth at the widest cross-section. For soft-sided items measure when fully expanded; for rigid cases measure the outer shell.

Wheeled suitcases, large duffel bags and oversized gear are not permitted through security. Small day sacks, purses, clear tote bags and soft coolers that meet the stated dimensions are acceptable. Medical equipment and infant supplies exceeding the limit should be presented to security for inspection – staff will advise on alternative on-site storage or exemptions.

How will personal bags be screened during security checks?

Open your personal bag and place loose items in a tray for a visual and manual inspection; remove large electronics and loose liquids ahead of arrival to speed processing.

Typical screening steps

Security follows a predictable sequence: exterior glance, instruction to open compartments, visual/manual inspection of contents, possible handheld magnetometer sweep or guest walk-through, and a detailed search if anything appears suspicious. Staff may ask for item explanations or documentation for medical supplies and mobility devices.

Step Staff action Your action Expected time
Initial check in queue Quick exterior look for obvious prohibited items Have your bag accessible and not wrapped or taped 5–15 seconds
Tray / visual inspection Open compartments; staff view contents and may ask to remove items Empty pockets, place small items in tray, remove sunglasses/hat 10–30 seconds
Metal-detect sweep Handheld sweep of bag or guest passes through walk-through unit Remove keys, coins, belts with large buckles; hold children if requested 5–15 seconds
Manual detailed search Staff manually inspect compartments and larger items Be present, verbally identify medications or medical devices 30–90 seconds
X-ray / conveyor screening (if used) Operator reviews image and may request opening specific pockets Place bag on conveyor and follow prompts; open requested pockets 10–40 seconds

Practical tips for faster clearance

Keep prescription medications in original labeled containers and carry a brief physician note for injected or unusual treatments.

Store chargers, batteries and small electronics in a single pouch; separate liquids or snacks into an easy-access pocket to avoid repeated handling.

Wear slip-on shoes and avoid bulky metal accessories to reduce secondary screening for the person; loosen belts with large metal buckles before arrival.

If handling strollers, coolers or medical equipment, have them unfolded and ready for inspection to minimise processing time.

Which attractions require loose items to be stowed or placed in lockers?

Stow all loose bags, daypacks, purses, hats, cameras and small handheld items in lockers or ride-side bins before boarding high-speed roller coasters and water attractions.

  • High-speed steel coasters (launch, hyper/giga, and signature looping coasters) – items can be ejected at extreme speeds; lockers or ride platforms with bins are required at many access points.
  • Inverted, floorless and wing-style coasters – open-seat or hanging designs prevent secure storage on the rider; park staff will request all packs and loose articles be stowed.
  • Spinning and free‑spin rides – centrifugal force easily dislodges loose objects; small zippered pouches on the body are sometimes allowed if fully secured, otherwise use lockers.
  • Log flumes, rapids and splashdown attractions – water exposure and sudden drops mean items will be lost or damaged; lockers at the ride or park locker areas are provided for this purpose.
  • Drop towers and pendulum/swinging rides – rapid vertical motion increases risk of item loss; staff generally requires removal of loose bags and unsecured items.
  • Skyways, gondolas and some family flat rides – policies vary by attraction; when signage or attendants request stowage, follow their instruction and use nearby lockers or bins.

Practical steps for compliance:

  1. Use ride-side lockers (or the park’s main locker area) before queueing for any major coaster or water ride.
  2. If riding with a companion, hand over bags to them for safekeeping off-ride.
  3. Keep phones and wallets in zippered, body‑worn pouches or secured inside coat pockets with zippers if staff allows; otherwise use a locker.
  4. Look for posted signage at each attraction and follow instructions from ride operators – refusal to stow items may result in denied boarding for safety reasons.

Where are park lockers located, what are rental procedures and fees?

Use on-site lockers at the main entrance plaza, central midway near the largest coasters, and adjacent to the waterplay area; additional locker banks sit by Guest Services and family zones.

Rental steps: locate a locker bank, select size on the touchscreen, pay with credit/debit or contactless mobile wallet, receive a numeric PIN (and printed receipt when available), store items and close the door – the unit will lock automatically. Retain the receipt and PIN; staff can reset a unit only after ID verification.

Accepted payments and access: most locker kiosks accept Visa, MasterCard, debit, and Apple/Google Pay. Electronic lockers use PIN codes (no physical key), openable at any time during the rental period with that code.

Typical sizes and same‑day rates: small ~12″×12″×12″ – $12; medium ~17″×17″×17″ – $18; large ~30″×18″×18″ – $25. Waterproof or oversized units near water attractions often carry higher fees ($20–$35). Rates are per operating day; extensions may require an additional charge.

Hours, reservations and last rentals: lockers operate during park hours; rentals usually end at park closing. Last-time rental terminals often stop accepting new rentals about 30 minutes before close. Some parks allow online reservation for select locker banks – check Guest Services on arrival.

Lost PIN or disputes: visit Guest Services with photo ID and your receipt; staff will verify ownership and may reset the locker. Fees for staff-assisted access or lost-receipt processing vary by location.
