Camping at the Coast & Beach: Tides, Wind, Sand and the Rules

Camping by the sea: what is different?

Camping by the sea adds a moving water line, open exposure and ground that holds pegs badly. None of it is difficult once you know it.

• The water moves. Where the coast has tides, the sea rises and falls twice a day, and wind can push it higher than the tide table says.
• The wind is stronger and steadier. Nothing breaks it over open water, and it carries sand into zips, pots and eyes.
• The ground is sand or shingle. Standard pegs pull out; you need different anchors.
• There is little shade and no fresh water. Sun reflects off sand and water, and all the water around you is salty.
• Much of the coast is protected. Dunes, salt marshes and breeding areas are fragile, and camping is often not allowed at all.

Is beach camping allowed? Rules come first

In many countries the answer is no, or only in designated places. Beaches and dunes are popular, fragile and often part of protected areas, so wild camping and open fires there are widely prohibited. In Germany, for example, the Wadden Sea coast is protected as national parks, dunes are protected both for nature and for coastal defence, and camping on beaches and dunes is generally not permitted outside campsites. Rules differ by country, region and even by beach section; this article is not legal advice. Our guide to wild camping rules explains the general legal picture and the alternatives.

The legal options at the coast are usually coastal campsites, some trekking or bivouac sites, and in a few countries with a right of access, beaches where a single night is tolerated as long as you leave no trace. Signs at beach entrances, local authority websites and national park visitor centres tell you what applies. If a beach is fenced off, signposted as a nature reserve or marked as a breeding area, that settles it. The glossary entry on wild camping gives the short definition.

Tides and camping: how to read a tide table

Tides are the regular rise and fall of the sea caused mainly by the moon. On most Atlantic and North Sea coasts there are two high waters and two low waters a day, with roughly 12 hours 25 minutes between one high water and the next. That means high water comes about 50 minutes later each day: if it was at 06:40 today, expect it around 07:30 tomorrow. Other seas behave differently. The Baltic and the Mediterranean have only very small tides, but there the water level still changes with wind and air pressure.

A tide table lists the times (and usually the heights) of high water (HW) and low water (LW) for a specific harbour or gauge. National hydrographic services and harbour offices publish them, and many weather and marine apps show them. Use the station nearest to your beach; times can differ by an hour or more along the same coast, and the difference between high and low water ranges from a few centimetres to several metres.

The rule of twelfths: how fast does the water rise?

The tide does not rise evenly. A classic sailors' rule of thumb, the rule of twelfths, splits a rising tide of about six hours into hours: the water rises by 1/12 of the range in the first hour, 2/12 in the second, 3/12 in the third and fourth, 2/12 in the fifth and 1/12 in the sixth. Half the rise happens in the middle two hours. On a flat beach or mudflat, that is when the waterline can advance surprisingly fast across the sand. Real tides vary, so treat this as an approximation, not a timetable.

Spring tides, neap tides and storm surges

Around full moon and new moon, usually a day or two after, the tidal range is largest: high waters are higher and low waters lower. These are spring tides (nothing to do with the season). Around half moon the range is smallest: neap tides. If the wrack line you see was left by a neap tide, a spring tide later in the week can come further up the beach.

The bigger danger is weather. Strong onshore wind and low air pressure push water against the coast, so the sea can rise well above the level in the tide table. A severe version is a storm surge, which can flood beaches and the foot of the dunes completely. National weather and maritime services issue warnings for this. Check the wind forecast together with the tide table, as our weather guide explains, and with a surge warning, do not sleep on the beach at all.

Sandbanks, mudflats and getting cut off by the tide

On flat coasts the tide does not only climb the beach, it also floods behind you. At low water, sandbanks and mudflats invite you to walk far out. As the tide turns, the lowest ground fills first: tidal creeks and channels between the sandbank and the shore. You can stand on dry sand and already be cut off from the beach.

Mudflats such as the Wadden Sea add soft mud, channels that are deeper than they look and sea fog that can remove all orientation within minutes. Walking on the mudflats (often called Wattwandern in Germany) should only be done on guided tours with local, certified guides who know the tides and routes; in national parks, large areas are closed anyway. Do not walk out alone, do not walk towards an incoming tide, and turn back early. The navigation basics in navigation do not replace local knowledge here.

Choosing a campsite at the coast

The general method from choosing a campsite applies: think about water, wind, ground and hazards. At the coast, the order of priorities changes.

• Height above the sea first. Above the highest wrack line, with a margin, out of reach of spring tides and waves.
• Off the dunes and vegetation. Dune grass, salt marsh and shingle plants are fragile. On campsites, the pitches behind the dune belt are often the sheltered ones.
• Not at the foot of cliffs. Cliffs erode and drop stones, especially after rain and frost. Keep clear of the base and the edge.
• Not in a hollow or creek bed. Rain and high water both collect in low ground, and a dry tidal creek can fill from the sea.
• Away from river mouths. Water from inland and from the sea meet there, and channels shift.

Look at the ground itself too. Dry, loose sand at the top of the beach is soft to lie on but holds anchors poorly and blows around in wind. Firmer, slightly damp sand holds anchors better, but on the beach it usually lies lower, closer to the water. Shingle is stable and drains well but is hard and noisy; a thicker sleeping pad helps.

Wind and sand: pitching a tent on the beach

At the coast, wind is the normal state. On sunny days a sea breeze often blows from the sea onto the land during the afternoon, and at night it may turn to a weaker land breeze. On top of that come the weather systems, which hit the coast without trees or hills to slow them. The principles from camping in wind apply fully: plan for the gusts, pitch low, point the narrow or low end into the wind and put the door on the lee side. For a quick check of a forecast, the wind and Beaufort camp calculator turns mean wind and gusts into camp advice.

Sand adds its own problems. From a moderate breeze, dry sand starts to move close to the ground, gets into zips, under flysheets and into food, and sandblasts anything left in the open. Keep the tent closed on the windward side, store gear in closed bags or dry bags, and cook in the lee of the tent, not on the windward side where sand flies into the pot.

Pitching sequence on sand

Anchor first, unfold second, exactly as in a storm. Prepare your deadmen before you open the tent bag, bury the windward anchors, attach the tent and let the wind stretch it downwind. Then add the lee side and every guyline. A tarp works too, but only as a low A-frame with the windward edge close to the sand; a high, open tarp is mainly a sail at the coast. The tarp shelter guide shows the pitches, and the tarp pitch planner helps with heights.

Coastal air is humid, and the night often brings heavy dew. Expect the outside of the tent to be wet in the morning even without rain, and keep some ventilation open on the lee side. More on airflow in choosing a tent.

Anchoring in sand: deadmen, sand stakes and buried sacks

Normal pegs hold by friction in compact soil. In loose sand there is little friction, so a peg pulled sideways by a guyline simply slides out. The answer is to spread the load over a larger area under the surface: a deadman anchor. The table in our guide to stakes and anchors for every ground gives the same rule: bury the anchor 20–30 cm deep, crosswise to the pull.

Other anchors for sand and shingle

• Sand stakes: wide, long stakes with a large surface hold better than thin pegs in sand. Push them in at an angle away from the tent and bury them completely, lying flat and crosswise, when the wind is strong.
• Normal pegs as deadmen: two or three pegs tied together in the middle and buried crosswise work like a stick.
• Rocks on shingle: tie the guyline round a heavy rock and pile a second on top. Pegs can also be wedged between pebbles.
• Driftwood: a solid piece of dead driftwood, buried crosswise, is a good deadman. Leave large driftwood piles alone; they are habitat, and in some protected areas you may not take anything.

In the morning, undo the hitch, dig the sack out and fill the trench so no holes are left for others to fall into.

Sun, heat and shade on the beach

The beach is one of the hottest places to camp on a sunny day. There is little natural shade, and sand and water reflect sunlight, so you get sunburnt faster than inland, even when a sea breeze feels cool. A closed tent in full sun quickly becomes unbearably hot. Plan shade from the start: a tarp pitched as a low sun roof with the edge towards the sun, guyed out for the afternoon breeze and anchored with deadmen, gives a cool place to rest at midday.

Wear a hat, light long sleeves and sunglasses, use sun cream generously and reapply it after swimming. Rest in the shade in the hottest hours, drink to a plan and know the signs of heat exhaustion and heat stroke. Our guide to hot weather and heat illness has the first aid; for a confused or collapsed person call 112 at once.

Fresh water at the coast: seawater is not drinkable

All the water around you is undrinkable. Seawater contains so much salt that drinking it dehydrates the body further; that is true even in small amounts. Normal water filters, purification tablets and boiling do not remove salt. Producing fresh water from seawater by distillation or a solar still is possible in principle but slow and gives very little, so it is no plan for a camp.

Bring all the water you need, or know exactly where you can refill: campsites, public taps, cafés or harbour facilities. Our guide to refilling water on the trail covers where to find taps and how to plan the gaps, and the water calculator estimates how much you need for your weight, effort and temperature. Wind and sun dry you out faster than you notice, so plan generously, as hydration and dehydration explains. Streams that reach the beach often flow through farmland or settlements; if you must use them, treat the water as described in water purification.

Campfire on the beach: often banned, never in the dunes

Open fires on beaches are prohibited in many places, and in dunes, near grass and in protected areas practically everywhere. Dry dune grass burns fast, and coastal wind spreads sparks far. Check the local rules and any fire ban first; this is not legal advice. Where fires are allowed, many beaches have designated fire spots or only allow barbecues on stands. A stove is usually the simpler choice; see camp stoves and keep it in the lee of the tent.

If a fire is permitted, keep it small, on bare sand or shingle below the vegetation and well away from dunes, driftwood piles and dry grass. The site-wide distances apply: at least 5 m from tents and at least 3 m from synthetic tarps, and the fire downwind of your shelter. Our campfire safety guide covers the rest.

Nesting birds, seals and other wildlife

Beaches and dunes are breeding places. Several shorebirds lay their well-camouflaged eggs directly on sand or shingle, and a single person or dog walking through can keep the parents off the nest long enough for the eggs or chicks to die. During the breeding season, roughly spring to late summer depending on region and species, many beach sections are therefore closed and marked with ropes and signs.

• Respect closures and signs; never enter fenced breeding areas.
• If birds circle you calling loudly or pretend to be injured, you are close to a nest: leave the way you came.
• Keep dogs on a lead where required; many beaches ban them in the season. See camping with dogs.
• Keep well away from seals resting on beaches or sandbanks and use binoculars. A lone seal pup is usually not abandoned; do not touch it and report it to the local authorities if you are worried.
• Store food in closed containers: gulls and foxes learn fast.

Salt marshes and dune slacks can bring mosquitoes and ticks; the measures in ticks and insects help, and our wildlife guide covers food storage in general.

Cold water and swimming safety

A swim belongs to a beach camp, but the sea is not a lake. Many northern seas are cold even in summer, and sudden immersion in cold water causes a gasp reflex and fast breathing; the phases are explained under the 1–10–1 principle. Currents, waves and tidal flows can carry even good swimmers away.

• Swim at beaches with lifeguards and follow the flags and signs.
• Never swim alone, at night, after alcohol or in tidal channels and harbour entrances.
• Enter cold water slowly and stay close to the shore.
• If a current pulls you out, do not fight it head-on: swim parallel to the beach or float, raise an arm and call for help.
• Do not swim out after inflatables or air mattresses blown out to sea by offshore wind.

Out of the water, get children dry and warm quickly: wind on wet skin chills fast (see bushcraft with kids). In an emergency call 112 (EU) or your local emergency number.

Salt and sand: caring for your gear

Salt and sand wear gear faster than anything in the forest. Sand grinds zips and fabric coatings, salt crystals attract moisture so things never quite dry, and salt water corrodes metal stakes, zip sliders, stove parts and knife blades. A few minutes of care after a coastal trip prevents most damage.

On the trip, keep sleeping bags, clothes and electronics in closed bags; a dry bag keeps out both spray and sand. Carry spare cord and a small repair kit with tape and a needle for tie-outs that the wind rips out. Phones and power banks dislike sand and salt; a zip bag is cheap protection.

Leave no trace at the coast

Coasts collect rubbish from the whole sea, and every camper adds to it or takes some away. The principles of Leave No Trace apply with a few coastal points:
