What to Do in a Kent Seaside Town on a Rainy Day: 12 Indoor Ideas

Rain on the Kent coast is not a disaster. It is a change of programme. The beaches empty, the light over the harbour turns flat and silver, and the towns do what they have always done in bad weather: they move indoors. Margate, Ramsgate, Broadstairs, Whitstable, Herne Bay, Deal, Folkestone and Dover all keep something worth crossing town for, from chalk caves and wartime tunnels to volunteer-run museums, independent cinemas and cafes where nobody rushes you along. What follows is a wet-day plan sorted by what you actually feel like doing rather than by postcode. Assume you will still get wet between venues, and dress for it.

Galleries and museums that swallow an afternoon

Turner Contemporary, Margate

The obvious first stop, and still the best one. It sits on the harbour arm, free to enter, with tall windows that make the weather part of the experience — a grey sea looks considerably better from inside a warm gallery than from a wind-blown promenade. There is a cafe, a shop, and enough floor space that a sudden downpour does not turn the place into a scrum. Check the day you plan to visit; like most galleries it closes at least one day a week, and opening patterns shift with the seasons.

Powell-Cotton Museum, Birchington

A short drive west of Margate and one of Kent's stranger treasures: a family museum of natural history and world cultures, with whole-room dioramas that have a genuine atmosphere. It is quieter than the seafront attractions, which on a wet Saturday is exactly the point. The grounds are lovely in dry weather and irrelevant in wet, so save your energy for the rooms inside.

The small museum circuit

Kent's coastal small museums are run largely by volunteers, which means plenty of charm, serious local knowledge and limited opening hours. Whitstable Museum and Gallery, Herne Bay Museum, the museums in Deal, Folkestone Museum and Dover Museum all fit that description. Pick one and treat it as a reason to explore a high street you would otherwise drive past. Check the website on the morning you go — a sign in the window reading "closed today" is a real possibility out of season.

Go underground

If there is one wet-day trick that never fails, it is going below ground, where rain simply is not a factor.

• Ramsgate Tunnels: the deep shelter tunnels dug beneath the town in wartime, visited on guided tours. Atmospheric, surprisingly long, and unlike anything else on this coast. Book ahead in the holidays.
• The Shell Grotto, Margate: a small underground chamber lined with shells set into patterns, and no one is entirely sure why it is there. Allow half an hour rather than an afternoon, but do go.
• Margate Caves: chalk-cut caves reclaimed and reopened after years shut, with carvings and paintings to look at.
• Dover Castle's wartime tunnels: the command rooms and hospital tunnels beneath the castle, where the Dunkirk evacuation was partly coordinated. Run by English Heritage; a timed ticket may be needed.

These are underground spaces with steps, uneven floors and the occasional low ceiling. If anyone in your group has mobility issues or dislikes enclosed spaces, check access before you book.

Arcades, cinemas and other indoor amusements

Seaside arcades are the traditional answer to rain, and Kent still has plenty along the Margate, Ramsgate, Broadstairs and Herne Bay seafronts. Bring coins, set a limit, and accept that the penny machines will take more of your money than the big ones. Dreamland in Margate keeps its indoor amusements going when the rides do not, so a wet morning does not waste the trip.

For something calmer, look at the independent cinemas and arts venues: the Palace Cinema in Broadstairs, the Silver Screen in Folkestone, the Horsebridge in Whitstable, and the small theatres and music venues in Margate and Ramsgate that programme film alongside live shows. A mid-afternoon screening is a perfectly legitimate way to spend a wet day. Families with younger children should also note the soft-play centres and bowling alleys tucked into the retail edges of most of these towns.

Cafes, bookshops and the slow option

Not every wet day needs an itinerary. Margate Old Town, Whitstable's Harbour Street, Broadstairs' Albion Street and Deal's High Street are all good for a slow loop of cafes, secondhand bookshops and small galleries, finishing in a pub with a fire.

A few things make that work better:

• Choose somewhere with room to sit. Ten seats and a queue is not a wet-day refuge.
• Eat at the counter or book ahead. Small coastal cafes fill up fast when it rains, because everyone had the same idea.
• Ask the staff what they would do. The person making your coffee has usually lived there for years and knows which museum is genuinely open.

A wet-day route you can copy

If you would rather not decide anything on the day, this is a reliable Margate shape for half a day:

1. Late morning at Turner Contemporary, while the rain is heaviest.
2. Lunch in the Old Town — a proper sit-down, not a sandwich eaten standing up.
3. Early afternoon at the Shell Grotto or the Caves.
4. Late afternoon in the arcade, then a cinema or a pub.

For an eastern version, book Ramsgate Tunnels for the morning, eat by the harbour, then take the short hop to Broadstairs for the Dickens House Museum, a film at the Palace, or tea and cake on Albion Street.

Before you set off

The biggest mistake on a wet coastal day is assuming everything will be open.

• Check times on the morning itself. Many Kent coastal museums are seasonal or volunteer-run, and winter hours are short.
• Book anything guided. Tunnels and castle tours sell out, especially during school holidays.
• Carry coins and a little cash. Arcades want change, and smaller cafes are not always reliable with cards.
• Wear something that can get wet. You will walk between venues, and fifteen minutes in the rain is part of the day.
• Have a second option ready. If the gallery is shut or full, the fallback is always a cafe with a window and a long lunch.

Do that, and a rainy day on the Kent coast stops being a washout and becomes the sort of afternoon you end up recommending to other people.
