How to Pack a Sustainable Seaside Picnic

Why the seaside changes the way you pack

A picnic on a windswept Northumberland beach and a lazy afternoon on a sheltered Cornish cove ask quite different things of your cool bag. Wind, sand, salt spray and the complete absence of a bin within half a mile all conspire against the sort of lunch that comes wrapped in layer upon layer of plastic. The good news is that packing a sustainable seaside picnic is not about austerity. It is about choosing food and kit that taste better, travel better and leave nothing behind but a few crumbs for the gulls.

The guiding principle is simple: whatever you carry in, you carry out. Once you accept that, weight matters, packaging matters, and single-use plastic stops looking like convenience and starts looking like a chore you will be babysitting all afternoon.

Start with what you carry it in

Before you think about food, think about the vessel. A decent cool bag or insulated rucksack keeps cheese, dairy and cooked meats at a safe temperature on a warm day, and it doubles as somewhere to stash rubbish on the way home. Inside it, reusable lidded tubs with clip-down sides are far better than foil or film, because they survive being sat on, dropped on shingle and buried briefly by an enthusiastic child.

• Stainless steel or glass-lined flasks for tea, coffee or chilled water — one good bottle beats six disappointing ones.
• Beeswax wraps and cloth bags instead of cling film, which turns into a flapping nuisance in a sea breeze.
• A couple of spare cotton tote bags, one for clean kit and one, clearly designated, for rubbish.
• Real cutlery and enamel or bamboo plates, or simply eat things that need no plate at all.
• A large lidded jug or bottle for squash or cordial, rather than a multipack of cans.

A small folding knife, a tea towel and a couple of damp cloths in a zip bag will handle almost every spill the coast can throw at you.

Build the menu around local, low-waste food

This is where a seaside picnic becomes genuinely better than a supermarket meal deal. Buy a loaf from a local bakery and ask for it unwrapped, or take your own cloth bag. Have cheese cut from the counter and popped straight into your own tub. Fruit from a greengrocer, loose and unbagged, travels perfectly well in a cotton sack.

• A good loaf — sourdough, a crusty cob or soda bread — torn rather than sliced, with a tub of decent butter.
• Local cheese and perhaps a handful of tomatoes or radishes, which need no dressing and no plate.
• Seasonal fruit: apples, plums, peaches, a punnet of strawberries decanted from its plastic tray at home.
• Something substantial such as a frittata, a slab of pork pie or a pasty, carried in a tub rather than a bag.
• Oatcakes or nuts in a screw-top jar instead of a multipack of crisps.

Buying loose and local is not just less wasteful; it usually tastes better, supports the shops that keep small coastal towns alive, and means your lunch has a story worth telling while you eat it.

Drinks, snacks and the awkward bits

Drinks are where good intentions usually collapse. A flask of tea is a small triumph on a cold beach; a bottle of cordial diluted at home saves a bagful of cans. If you do take cans or glass, take them home again — recycling bins on seafronts are often overflowing by mid-afternoon, and glass on shingle is a genuine hazard for bare feet and dogs' paws.

Snacks are easy to get right. Fill a jar with roasted nuts, make a batch of flapjack cut into squares and layered in a tub, or take a few squares of good chocolate. Ice lollies and ice cream from a seafront kiosk are part of the pleasure of the day, so enjoy them — just choose a cone over a tub and a wooden stick over a plastic spoon where you can.

Eating well and leaving nothing behind

Keep lids on tubs between servings, because sand gets into absolutely everything and gulls are bold, intelligent and entirely unrepentant. Never feed them: it encourages aggressive behaviour, harms their health and makes the beach less pleasant for everyone after you.

When you have finished, do a slow sweep of your spot. Bottle tops, cling film corners, cherry stones and napkins all blow away faster than you would believe. A quick two-minute beach clean before you leave — a few pieces of fishing line, a balloon fragment, a stray wrapper — is a small act that adds up when thousands of us do it.

Take only photographs. Leave shells, pebbles, driftwood and seaweed where they are, because they are habitat and coastal defence as much as decoration, and some sites are legally protected. Keep to the path on dunes, where nesting birds and fragile plants suffer from trampling, and give seals and seabirds plenty of room.

A quick checklist before you leave the house

• Cool bag, ice block, reusable tubs with lids.
• Flask, water bottles, cordial.
• Cloth bags, beeswax wraps, cutlery, tea towel.
• Rubbish bag and a spare bag for a mini beach clean.
• Sun cream in a refillable bottle, hats, and a windbreak if the forecast is breezy.

Pack once, pack well, and the coast does the rest.
