Skinny dipping in the UK: where and how to do it

Skinny dipping is one of the simplest pleasures there is: no wet costume clinging to you, no changing under a towel, just you and the water. It is also more common than you might think. In a 2022 Ipsos poll commissioned by British Naturism, 21% of people in Britain said they had been skinny dipping. This guide to skinny dipping in the UK covers what the law says, how to stay safe in cold British water, where to go and how to join an organised dip.

Is skinny dipping legal in the UK?

The short answer is yes, as long as you are not doing anything sexual or deliberately upsetting people. The detail depends on where you are.

England and Wales

There is no law that makes being naked in public a crime. The offence of exposure under section 66 of the Sexual Offences Act 2003 requires an intention to cause alarm or distress, and the College of Policing says Parliament worded it specifically to avoid catching naturists. Its decision aid for police lists swimming, sunbathing and walking naked as “passive behaviours”. If someone is simply naked in public, police call handlers are told to explain that no offence is being committed and that no police action is necessary.

Things change if behaviour turns disorderly and actually causes someone harassment, alarm or distress, or if there is any sexual element. Naturism is non-sexual, and so is a good skinny dip.

Scotland

Scotland has some of the best wild swimming in Europe and generous access rights. Under the Land Reform (Scotland) Act 2003, the Scottish Outdoor Access Code includes swimming in rivers, lochs and reservoirs as part of your access rights, as long as you act responsibly and follow any local byelaws. There is no detailed Police Scotland guidance on nudity. British Naturism says police consider each case on its merits, so choose quiet places and be considerate.

Northern Ireland

The Police Service of Northern Ireland also has no detailed guidance of its own and, according to British Naturism, considers each case on its merits. The same common-sense approach applies: somewhere quiet, nothing sexual, and respect for anyone who turns up.

Wherever you are, the land and water still belong to someone. Respect private property, signs and swimming bans.

Cold water shock: the real risk

The law is rarely the problem. Cold water is. The RNLI warns that water below 15°C can trigger cold water shock, and UK seas, rivers and lakes are below that for much of the year. Cold water shock makes you gasp and lose control of your breathing. It also sends your heart rate and blood pressure up quickly, which can lead to cardiac arrest.

Skinny dippers have no wetsuit at all, so take this seriously even in summer.

RNLI advice: Float to Live

If you get into trouble in the water, the RNLI’s advice is to fight your instinct to thrash about and swim hard. Instead:

Tilt your head back with your ears under water.
Relax and try to breathe normally.
Move your hands and legs to help you stay afloat, or spread your arms and legs for stability. It is fine if your legs sink.
The worst effects of cold water shock pass in less than a minute. Once your breathing is under control, call for help or swim to safety.

If you see someone else in difficulty, call 999 or 112 and ask for the Coastguard if you are at the coast (inland, ask for the Fire Service). Tell them to float on their back, throw them something that floats, and do not go in after them.

Safe skinny dipping checklist

Based on Royal Life Saving Society UK advice:

Never swim alone. Go with a friend, and tell someone else where you are going and when you will be back.
Plan your way out before you get in. Know your exits, and check tides, currents and wind.
Get in slowly. Do not jump or dive into water when you cannot see the bottom.
Stay close. Swim parallel to the shore, ideally where you can stand.
Keep it short. In cold water, RLSS UK suggests under 10 minutes in just a costume, and the same goes for no costume. Beginners should avoid water below 12°C.
Warm up straight away. Have a towel, warm layers and a hot drink ready. Your core temperature can keep dropping after you get out, known as afterdrop.
Check the water quality. Avoid swimming after heavy rain, never swim in blue-green algae, and check the Surfers Against Sewage Safer Seas and Rivers Service or the Rivers Trust sewage map.
Skip it if you have been drinking, if you feel unwell, or near weirs, locks and estuary mouths.

Wild swimming etiquette for skinny dippers

Being lawful is one thing. Being welcome is another. A few habits keep skinny dipping relaxed for everyone:

Choose your spot. A quiet stretch of river or a remote beach early in the morning is very different from a busy family swimming spot on a hot Saturday.
Read the room. If a family or a school group arrives, a towel or swimsuit to hand lets you be considerate without fuss.
Share the water. Scotland’s access code asks swimmers not to disturb anglers or other water users, and to avoid fishing nets and tackle. That is good manners anywhere.
Tread lightly. Get in and out where you will not damage banks or disturb wildlife, and take everything home with you.
No photos of others. Never photograph other swimmers without asking.

The Great British Skinny Dip

If you would rather dip with company, the Great British Skinny Dip is the easiest way in. Run by British Naturism, it is a nationwide programme of naked swims raising money for the British Heart Foundation. It celebrated its tenth year in 2025, when more than 500 dips were listed, and British Naturism held a synchronised skinny dip day on 7 June that year.

Dips take place at naturist clubs, outdoor pools and lidos, and indoor public baths booked for the evening. Some run all year: in October 2026 the calendar still lists weekly Saturday dips at one venue and a session at Withington Baths in Manchester, which hosts a monthly swim. If you are new to swimming naked, say so when you book so the organisers can look out for you.

To find one:

Go to the Great British Skinny Dip calendar on the British Naturism website.
Use the Distance button and enter your postcode and how far you will travel.
Check the listing for booking and entry details. Money raised goes to the BHF.

You can also host your own dip, at a club, a pool or with friends, and register it with the organisers. It is a sister event to the clothing-optional Naked Heart Walks, and we list both on our UK naturist events page.

Naturist beaches: the easy option

The College of Policing notes that many naturists use beaches known as naturist beaches. There is no legal power to designate them, but they have a long tradition of nudity, and that makes them the most relaxed places in the UK for a sea swim with nothing on. You will not be the only naked person there, and nobody will bat an eyelid.

Popular spots include Studland Bay in Dorset and Brighton’s naturist beach. Browse our full list of UK naturist beaches to find one near you. The same water safety rules apply: most are not lifeguarded, so swim with a friend and stay within your depth.

Prefer warm water? Many naturist clubs have heated pools, and naturist spas and saunas are a gentle introduction if you are new to it all.

Where can I go skinny dipping in the UK?

Naturist beaches are the easiest choice. Naturist clubs with pools, and Great British Skinny Dip events at lidos and public baths, are good options too. For wild swimming, pick a quiet spot where swimming is allowed.

What is the Great British Skinny Dip?

It is a British Naturism programme of organised naked swims across the UK, raising money for the British Heart Foundation. Find dips on the British Naturism events calendar.

How cold is too cold for skinny dipping?

The RNLI says cold water shock can happen in water below 15°C. RLSS UK advises beginners to avoid water below 12°C and to keep cold swims under about 10 minutes without a wetsuit.

Do I need to be a naturist to skinny dip?

Not at all. Many people who skinny dip would never call themselves naturists. If you enjoy it, our first-time naturist guide is a good next step.
