Castaway Cay: What to Pack for the Best Day of a Disney Cruise

Castaway Cay is Disney’s private island in the Bahamas, and across our six cruises it’s the day we look forward to most. The ship docks right at the island, so you walk off onto a pier instead of tendering in on a small boat. The sand is white, the water is shallow and calm, and there’s a quiet adults-only beach down the path if you want a few hours away from the splash zone. Our advice every time: clear your whole day for it and don’t book anything that pulls you back to the ship early. What follows is the small stuff we bring to make the beach part easy, so the day stays the good kind of lazy. If you’d rather just check it off, grab the free printable packing checklist below.

1. Insulated Can Cooler — your drink goes warm in ten minutes otherwise

A canned drink on a Bahamian beach turns to bathwater fast, and the walk back to a bar is longer than you think when you’re settled in a chair. A good insulated can cooler keeps a soda or a beer cold for hours sitting right in the sand next to you. We each bring one and it’s the single thing we reach for most. This is the one item I’d never leave in the cabin.

2. Sunglasses Strap — so your shades survive the snorkel lagoon

The water at Castaway Cay invites you in, and the first time you duck under a wave your sunglasses are gone. A cheap strap loops onto the arms and lets the glasses hang around your neck when you’re swimming. It sounds fussy until you’ve watched a pair sink into the surf. We lost one good pair before we learned to clip in.

3. Crossbody Phone Lanyard — hands free for the whole walk and swim

You’ll want your phone for the photos — the ship from the beach is a great shot — but you don’t want to be clutching it across the sand or worrying about it near the water. A crossbody lanyard holds the phone flat against your chest, hands free, and it’s much harder to drop into the sand or the shallows. It also means you’re not digging through a beach bag every time you want a picture. Brigitte uses hers from the gangway to the beach and never sets the phone down.

4. Cooling Towel — relief on a beach with no shade

The main beach gets hot, and shade is scarce unless you’ve rented a cabana. A cooling towel is a piece of fabric you soak in the ocean or at a fountain, wring out, and drape over your neck. It stays cool well past what a regular towel does and it’s small enough to live in the beach bag. On a still, high-sun afternoon it’s the difference between staying out and giving up early.

5. Spray Sunscreen SPF 70 — fast reapplication for a full day in the open

A whole day on an open beach means reapplying sunscreen more than once, and rubbing lotion onto sandy, wet skin is miserable. Spray sunscreen covers fast, which is the whole point — you’ll actually reapply instead of skipping it. We go high SPF here because there’s no real cover and you’re in and out of the water all day. Hit the spots people always miss: ears, tops of feet, the back of your neck.

6. Collapsible Water Bottle — refill at the island stations, pack it flat

There are water stations on the island, so you don’t need to haul bottles off the ship. A collapsible bottle packs flat in the beach bag on the way out and refills full when you get there. Between the heat and the salt water, you drink more than you’d expect, and having your own bottle saves the walk. It rolls back down to nothing for the trip home.

That’s the short list — none of it is expensive, and all of it fits in one beach bag you can carry off the ship in one trip. Pack these and the day takes care of itself: walk off the pier, find a chair, and stay until they make you leave.
