What to Bring to a Water Park

Why these items are on the list

1. Swimsuit, worn under clothes. so you can get in the water right away — most parks have changing rooms if you'd rather arrive dressed
2. Sunscreen, SPF 30+. apply before you leave home, not in the parking lot, and reapply every two hours
3. Two towels. one for midday, one for the end of the day — a single wet towel isn't much help by afternoon
4. Water shoes or sandals with a heel strap. decks and pathways get slippery; flip-flops work for the walk in but not much else
5. Change of dry clothes. especially if staying for a meal afterward
6. Waterproof phone pouch or dry bag. the most-repeated "don't forget" item across every source
7. Reusable water bottle. many parks offer refill stations
8. Foldable, packable bag. lockers are small — a rigid tote won't fit, a soft bag that folds flat will
9. Sunglasses. reflected glare off water is stronger than typical outdoor light
10. Swim diapers. if bringing young children — required by most parks, regular diapers aren't allowed in the water
11. Basic first-aid items (band-aids). for the inevitable small scrapes

Each source is a single park's own blog, written to promote that park, with the actual packing advice repeated near-identically across all of them. A neutral, park-agnostic checklist — reusable for every water park trip, not tied to one destination's marketing page — is the more durable version of the same information.
