Every beach holiday fails in one of two ways: you arrive missing something essential and spend an afternoon of holiday time and double the local price acquiring it, or you have packed so much that you spend the week tripping over luggage. The fix is a specific, tested list — this one has survived multiple family trips from cold European winters straight onto tropical sand.
The non-negotiables (check twice)
- Passports with at least six months’ validity, and copies stored separately from the ports themselves.
- Child ID documents if travelling with anyone else’s children, plus written consent letters where required.
- Two payment cards from different networks, because one will inevitably be blocked “for security reasons”.
- Travel insurance policy number saved offline on your phone.
Sun and skin
Reef-safe SPF 50 sunscreen is cheaper at home and frequently unavailable at the destination — bring more than you think, roughly one 100 ml tube per four days per person. A factor-50 stick for faces and ears survives carry-on liquids limits and gets used twice as often as the big bottle. After-sun moisturiser, a wide-brim hat per person, and cheap sunglasses you will not mourn if they go into the sea complete the kit.
Water and sand equipment
Infant and toddler arm floaties plus a beach tent weigh almost nothing and transform shallow-water mornings. A microfibre towel per person packs to the size of a paperback and dries in an hour, letting you skip hotel towel deposits. Waterproof phone pouches have saved more holiday photos than any camera upgrade — take two, because one will be sand-logged by day three.
Clothing arithmetic that works
Seven-day beach packing that actually succeeds: three swimsuits per person (one wet, one drying, one wearing), four shirts, two pairs of shorts, one light long-sleeve for nights when the breeze arrives, and one layer that would survive a cool airport transfer. Children need one extra of everything, for reasons every parent already knows but refuses to learn in advance.
Footwear
Flip-flops or slides for everyone, one sturdy sandal or trainer per adult for ruin-visiting and boat piers, and water shoes for children on coral-adjacent beaches — the most undervalued fifteen euros in beach travel.
The medical pouch
Rehydration salts, paracetamol and ibuprofen, plasters, antihistamines, motion sickness tablets, tweezers, and a small bottle of antiseptic cover ninety percent of beach-week incidents. Prescription medication goes in original packaging with a copy of the prescription; a pharmacy abroad will otherwise refuse to help in the moment you need it most.
Snacks and hydration
A collapsible two-litre bottle per person pays for itself within two days at resort-side prices, and a pouch of salty snacks rescues the late-afternoon pool hours that no hotel shop seems open for. Powdered electrolyte sachets are lighter than sports drinks and genuinely useful on out-attraction days.
Electronics
One power bank of 10,000 mAh covers the family for a day out; multi-country chargers and a short extension lead turn the single, permanently out-of-reach bedside socket into six accessible ones. Tablet downloaded content is the quiet hero of flight delays and conservation of parental patience.
What to deliberately leave behind
Books that become sand-filled shelf decorations (bring two paperbacks maximum), beach chairs rented by every resort for one or two euro a day, and drone equipment unless you enjoy carrying it. Cut the packing list in one pass and the trip gets lighter immediately.
Organisation system
Packing cubes in one colour per person make finding anything in fifteen seconds possible and repacking for checkout feasible in under an hour. The list fits into two carry-size suitcases plus one backpack for a family of four — and every afternoon you spend in the water instead of a pharmacy is the real dividend.
