Why the quiet coast wins

Britain's best coastal weekends are rarely found where the ice-cream vans queue bumper to bumper. They are found one town along: in small harbours where fishing boats still outnumber visitors, where a bakery opens at eight and shuts when the bread runs out, and where the loudest thing on a Sunday morning is a gull arguing with the wind.

Timing matters more than destination. Aim for late May, June or September, and travel on a Thursday or Friday rather than a Saturday. Even in August, a town that feels packed at one o'clock is often empty by six, once the day-trippers have hit the A-road home. And book two nights, not one — a single night on the coast is just a long drive with a sea view.

• Go on a Sunday night. Rates drop, car parks empty and you get the harbour at its most honest.
• Check tide times before every walk. Estuary and causeway paths flood quickly, and the sea comes in faster than it looks.
• Carry a little cash. Small harbour cafés and honesty boxes still prefer it, and signal can be patchy.
• Pack for four seasons. A waterproof shell, a woolly hat and grippy trainers will see you through most of a British summer.

Alnmouth, Northumberland: big skies, small streets

Alnmouth sits where the River Aln meets the North Sea, a tangle of pastel houses, a hilltop church and a spit of dunes that rearranges itself with every winter storm. The beach is a mix of soft sand and pebbles, with rock pools at the northern end that keep children busy for hours.

Walk the estuary path south towards Warkworth — roughly an hour at an easy pace, with a castle waiting at the far end — or head north along the dune-backed sands towards Boulmer, where you will meet more dog walkers than tourists. In the village, the shop sells bacon, newspapers and remarkably good cheese; a harbour-side café does crab sandwiches when the boats have been out. Evenings belong to the pub, where the fire is lit in September and the conversation is mostly about weather and tides.

Stay in one of the old fishermen's cottages if you can. Expect low ceilings, whitewashed walls, a fold-out table and a view of the river from an upstairs window.

Crail, Fife: the East Neuk without the crush

Crail is the quietest of the East Neuk villages, and all the better for it. There is a proper working harbour, a 16th-century doocot on the edge of the golf course, and a maze of narrow wynds where washing lines run between stone walls.

The beach at Roome Bay is pebbles and rock pools rather than sand, so bring shoes you do not mind getting wet. The Fife Coastal Path runs both ways: east towards Fife Ness for wilder cliffs and seabirds, west towards the busier villages if you fancy a longer leg-stretch and a bus back.

Buy lobster or crabs from the sheds on the quayside when the boats land — usually late morning — and eat them on the harbour wall with bread and a lemon. On a Sunday, most of the village seems to be either at the harbour or in the gallery-café on the high street, nursing a flat white beside a rack of local paintings.

Aberdyfi, Gwynedd: dunes, estuary and a hilltop view

Aberdyfi, on the north side of the Dyfi estuary, is a Victorian seaside village that never grew up. Its beach runs for a mile of sand and shingle, and across the water the dunes at Ynyslas glow gold in late afternoon light. Walk up to the lookout above the village for a view along Cardigan Bay; on a clear day the outline of Cader Idris sits behind you like a sleeping animal.

The little station at Penhelig, on the Cambrian line, is one of the prettiest in Wales — arriving by train, with the estuary on one side and wooded hills on the other, is half the holiday. Crabbing off the jetty, a round of golf, or a slow pint at a pub with a slate floor: that is about the full agenda, and it is enough.

For interiors, this is slate country. Think sea-grass matting, white cotton, a wool throw over the arm of a chair and a bookshelf of local wrecks and walked paths.

Three more quiet harbours worth the detour

• Cemaes Bay, Anglesey — a tiny harbour, a pebble beach and a coastal path towards the cliffs at Cemaes Head. Bring a windproof layer; there is nothing between you and Ireland.
• Porthgain, Pembrokeshire — a handful of houses around old industrial ruins, with a deep blue harbour that looks almost Mediterranean in June and decidedly Atlantic in October.
• Findochty, Moray — whitewashed cottages, a curved harbour wall and dolphin-spotting from the headland on a calm morning.

Seaside interiors: the quiet coastal palette

Forget anchors and driftwood. The coastal rooms that actually feel restful are built on a simple palette: chalky off-white, slate grey, faded navy and the colour of wet sand. Add limed or painted wood, ticking stripe, wool, rattan and a little aged brass. Layer the lighting — a low lamp for evenings, a candle on the windowsill — and keep floors bare or rush-matted, so sand is easy to sweep.

Hang hooks by the door for soggy waterproofs, keep a basket of blankets near the sofa, and bring home one stone or piece of rope from the beach rather than twelve. A single well-chosen object reads as a memory; a shelf of them reads as a car boot sale.

Before you go, note the tide table in your phone, book the one restaurant the village has, and check that the chip shop opens on Mondays. Then leave the itinerary at home — the best quiet weekends fill themselves.
