Do I really need a waterproof bag?

Yes. If you are taking a boat to a beach or snorkeling, a 10-liter dry bag protects your phone, wallet, and a dry shirt from salt spray and sudden tropical downpours.

Can I just buy sunscreen when I get there?

If you are staying at a large resort, yes. If you are staying in a remote area or an island destination, imported sunscreen is often 3x the price of home. Bring your own.

Packing for a Tropical Beach Vacation

Limit yourself to a 40-liter carry-on to avoid checked bag fees and lost luggage. Focus on lightweight, moisture-wicking fabrics and pack exactly three swimsuits so you always have a dry one to wear.

Choose the right bag. Use a 40L soft-sided backpack. Hard-shell suitcases are difficult to maneuver on sand or uneven tropical paths and often exceed airline carry-on size limits.
Curate your clothing. Bring 3 pairs of shorts, 5 lightweight t-shirts or tank tops, 1 set of lightweight long-sleeved linen clothing for sun protection/evenings, and 3 swimsuits. Stick to synthetic or linen fabrics; avoid cotton, which stays wet and heavy.
Consolidate liquids. Ensure all liquids (sunscreen, bug spray, face wash) are in 3.4oz (100ml) containers or less, placed in a single quart-sized clear bag for security scanning.
Pack your footwear. Wear your bulkiest shoes (sneakers) on the plane. Pack one pair of high-quality rubber flip-flops and one pair of lightweight sandals. Do not pack more than two extra pairs.
