London with kids: from Harry Potter to the free museums, the full guide with real prices

There's one city in Europe where a child can stand in front of a real dinosaur skeleton, sit in the front of the top deck of a red bus and see the Hogwarts Express from the films, all on the same day. London is probably the most kid-friendly capital in Europe, and despite its upscale image, a lot of the best things there are free.

But the London of 2026 is not the London you knew from your last visit. There's new paperwork you must sort out before the flight, prices have moved, and there are a few tricks, mostly with transport and tickets, where knowing them or not is worth hundreds of pounds to a family. Here's everything you need to know, with the real numbers.

Before anything else: the ETA, the paperwork you can't forget

Since 2025, Israelis can't enter the UK with just a passport. Every traveler, including babies and children, needs an electronic entry permit called an ETA (Electronic Travel Authorisation). You apply in the official UK ETA app or on the government site gov.uk, photograph your passport and your face, and pay £20 per person (the price went up from £16 in April 2026).

The approval usually arrives within minutes to hours, but the government's guidance is to allow three working days to be safe, so don't leave it to the night before the flight. The good news: the ETA is valid for two years (or until the passport expires), allows multiple entries, and stays of up to six months per visit. A family of four pays £80, once every two years.

Watch out for copycat sites that charge inflated fees. Apply only through the official app or gov.uk.

When to fly, and what to do about the dark

London works with kids all year round, but each season adds up differently.

Fall (September to October): reasonable weather, relatively good prices, and the city isn't crowded. The Sukkot break is an excellent window: it isn't really cold yet, and the parks are at the height of their autumn colors.

Hanukkah (December 6 to 12, 2026): this is the week London is at its wintry best. The holiday decorations on Regent Street and Oxford Street are already lit, Winter Wonderland in Hyde Park is in full swing (more on that below), and Trafalgar Square hosts a giant public menorah lighting every year. The price: it's cold (5 to 10°C, 41 to 50°F), and it gets dark by four in the afternoon. With kids that actually works: you start the day early and spend the evening among the holiday lights.

Summer: the days are long and the parks are wonderful, but it's the most expensive and crowded season.

The early winter dark is not a reason to give up, it's a reason to plan differently: indoor attractions in the afternoon, and the things that need daylight, like the parks and the royal guard, in the morning.

Flights: which airport to land at

A direct flight from Tel Aviv to London takes about five and a half hours, and there's plenty of choice: El Al and Virgin Atlantic fly to Heathrow, Wizz Air to Luton and Gatwick, and easyJet flies the route too. But "the cheapest flight" isn't always the cheapest deal, because you also have to count the trip into the city:

• Heathrow: the closest and most convenient. The Elizabeth line runs from there to Paddington and central London in 30 to 35 minutes, for £15.50 per ride with contactless payment. Children under 11 travel free with a paying adult.
• Luton and Gatwick: the flights are cheaper, but the airports are farther out, and the train into the city can add £20 to £25 per person each way. A family of four that saves $60 per plane ticket and pays an extra £150 on trains hasn't saved anything, so do the full math before you book.

Getting around: the rules that save the most money

London's public transport is an attraction in itself, and it has three rules every visiting family should know:

Children under 11 travel free. Always on buses, and on the Tube, the DLR and the Elizabeth line when they're with a paying adult. Up to four children per adult. They don't need any ticket; you simply go through the wide gate together.

Ages 11 to 15 get the Young Visitor discount: half price for 14 days. Tourists aren't issued the local Zip card, but at any Tube station a staff member can load a 50 percent discount off the adult fare onto a regular Oyster card. Important: this is done only with a staff member at the station (not at a machine and not online), the child has to be there, and it's a good idea to bring a passport as proof of age. You do it once at the start of the trip, at the first station.

Adults don't need any ticket, just a contactless credit card. Tap the same card (or phone) every time you enter and exit, and the system works out the cheapest fare on its own. There's a daily cap: £8.90 for zones 1 to 2, which cover almost everything you'll want to see. In other words, an adult never pays more than that in a day, however many rides they take. Just make sure every adult has their own card, and always tap the same one.

One more tip from experience: with a stroller, the double-decker bus almost always beats the Tube. Not every Tube station has elevators, and the stairs are long. And for the kids, a ride in the front seats on the top deck of a red bus is worth more than half of the paid attractions.

The attraction you book before the flight: the Harry Potter studios

The Warner Bros. Studio Tour London (The Making of Harry Potter) is the reason half of all families fly to London in the first place, and it's the one attraction in the city that needs real advance planning: tickets are sold for a specific date and time, and over the holidays they sell out weeks or even months ahead. Book on the official site only, right after you book your flights.

• Price: adults from £58.50, children (5 to 15) from £47, under 5 free.
• How long: three to four hours inside, and with the travel it's almost a full day.
• Getting there: the studios are outside the city, near Watford. Take a train from Euston to Watford Junction (about 20 minutes), and from there the studios' branded shuttle. There are also direct buses from central London at an extra cost.
• Who it suits: for kids from 6 or 7 who know the films, it's a formative experience. With little ones who haven't seen Harry Potter, it's a waste of money and time.

Three more paid attractions that are worth the money

The Tower of London. Knights, executioners, ravens and the real Crown Jewels: history that feels like a movie. Adults £37, children (5 to 15) £18.50, under 5 free. The tours led by the Yeoman Warders are included in the price and are funny even if you don't understand every word of English.

The London Eye. Half an hour in a glass capsule above the Thames. Online tickets start at around £29 per adult, and the earlier you book, the cheaper it is. At the ticket office on the day you'll pay significantly more, so this is a five-minute booking that saves a family tens of pounds.

A West End musical. The Lion King has been running at the Lyceum Theatre for more than 25 years, and it's still the ultimate family musical. Tickets start at around £36 to £43 for midweek shows, and prices climb on weekends. It suits ages 6 and up, and children under 3 aren't admitted. Matilda is also an excellent choice for school-age kids.

The heart of London with kids: the free things

This is where London surprises. A city considered one of the most expensive in the world gives away for free what other cities charge a fortune for:

• The Natural History Museum. Dinosaur skeletons, a huge blue whale hanging from the ceiling, and an earthquake hall. Entry is free. During the holidays, book a timed entry ticket on the website in advance; it's free too.
• The Science Museum. Right next door, free entry, and whole floors of buttons you're allowed to press.
• The British Museum. The Rosetta Stone and the Egyptian mummies. Free. With kids, come for a focused hour and a half, not a whole day.
• The Changing of the Guard at Buckingham Palace takes place on set days at around 11:00, not every day. Check the schedule on the official site and arrive half an hour early for a good spot.
• The parks. Hyde Park with pedal boats on the lake, and the Diana Memorial Playground in Kensington Gardens: a huge life-size pirate ship, free, and one of the best playgrounds in Europe.
• The toy store of toy stores: Hamleys. Seven floors of the world's most famous toy store on Regent Street, with live demonstrations on every floor. Entry is free. Leaving without buying anything is a parenting challenge of its own.

A rule of thumb for London with kids: one day, at most one paid attraction, with free things around it. Both the budget and the kids last longer.

Hanukkah in London: the week it all comes together

If you're aiming for the Hanukkah break (December 6 to 12, 2026), hold off on booking your evenings, because in December London unwraps a gift of its own:

Winter Wonderland in Hyde Park runs from November 19, 2026 to January 3, 2027 (closed only on Christmas Day). It's a huge winter fairground: rides, carousels, ice skating, hot chocolate and market stalls. Entry itself is cheap if you book ahead online: £5.50 at the standard rate and £8.25 at peak times, and if you prebook activities worth £25 or more, entry is free. Worth knowing: the rides inside are paid separately and it adds up fast, so set the kids a budget in advance. Really.

The holiday lights on Regent Street, Oxford Street and Carnaby Street are on throughout December: a free and stunning evening walk, at exactly the hour when it's dark anyway. And in Trafalgar Square, a giant public menorah goes up every year with central candle lightings, which is quite an experience for an Israeli kid: Hanukkah in the middle of London.

If you're still deciding between destinations for the December break, you'll find a wider comparison in where to fly with kids over Hanukkah.

Food, kosher and everything in between

London is a food paradise with kids, but it charges accordingly. A simple family meal at a restaurant will cost £60 to £100. Three ways to bring the bill down: the supermarket chains (Tesco, Sainsbury's, M&S), with Meal Deals of a sandwich, snack and drink for under £5; food markets like Borough Market, where everyone picks their own stall; and family-friendly pubs that serve a Sunday roast at lunchtime.

For families who keep kosher, London is one of the easiest destinations in Europe: the Golders Green and Hendon neighborhoods in northwest London have a large concentration of kosher restaurants, bakeries and kosher supermarkets, about 20 minutes on the Tube from the center (the Northern Line). You can stay in the center and still have a hot kosher dinner every day.

Where to stay, and the truth about London hotel rooms

This truth hurts: London hotel rooms are small, and a real family room for four is rare and expensive. Three strategies that work:

• Budget chains (Premier Inn, Travelodge): real family rooms for two adults and two children, often with free kids' breakfast, at £120 to £250 a night depending on the area and the date. For a family, this is almost always the best deal.
• An aparthotel with a kitchenette: more expensive per night, but a homemade breakfast and a reheated dinner save tens of pounds a day, and with small kids, your sanity too.
• Recommended areas: South Kensington (walking distance to the museums and the parks), Paddington (the Elizabeth line straight from Heathrow, near Hyde Park, and the bear from the films as a bonus), or the South Bank (the London Eye and the Thames riverside walk). All three are safe, convenient and well connected.

What it really costs

A family of four (two adults and kids aged 6 and 9), five nights over Hanukkah week:

• Direct flights for four: £1,000 to £1,600, depending on how early you book and which airport.
• ETAs: £80.
• Hotel (a family room at a budget chain), 5 nights: £700 to £1,250.
• Transport: about £150, covering the daily cap for two adults and the train from Heathrow and back, with the kids free.
• Attractions: the Harry Potter studios (£211 for four), the Tower of London (£111), plus Winter Wonderland or the London Eye: around £400 to £500.
• Food: £600 to £1,000 for five days, depending on how much is supermarket and how much is restaurants.

Total: around £3,000 to £4,500 for the family, roughly NIS 14,000 to 20,500. You can come in under that with early flights, an apartment with a kitchenette and more "museums and parks" days, and of course you can also go well above it. A full breakdown of a family trip budget, for any destination, is waiting in what a family trip abroad costs.

Questions that keep coming up

How many days do you need? Four or five full days is the minimum that justifies the flight, and a week is comfortable. With less than that, you'll be racing between attractions without time to breathe.

From what age is it worth going? The city works at any age, but the sweet spot is 5 or 6 and up: old enough for the museums and Harry Potter, young enough to get excited about a red bus.

Should you buy a London Pass or a combined attractions ticket? For most families, no. These passes only pay off if you squeeze two or more paid attractions into every day, and that's a pace kids can't keep up. Simply adding up the attractions you'll actually do almost always comes out cheaper.

Rain: how much of a problem is it really? Less than you'd think. London rain is mostly a drizzle that comes and goes, and the city is built for it: the museums are free, so a rainy day simply becomes a museum day with no sense of loss. A hooded jacket for everyone beats umbrellas, which will break anyway. A full packing list is waiting in what to pack for a family trip abroad.

Disneyland or London? A fair question for ages 3 to 8. Disneyland Paris is one deep experience; London is ten different ones. If you're weighing the other direction, see the full guide to Disneyland Paris.

London is one of Europe's more expensive destinations for families, so it's worth doing the overall budget math explained in the family trip abroad guide before you book, not after.

How to turn this into an itinerary without drowning in tabs

London with kids is a classic optimization problem: one timed attraction a day, short walking distances around it, a balance between paid and free, and flexibility for a rainy day. Diretix builds this in a few minutes of conversation: a full day-by-day itinerary matched to your family's ages, pace and budget, including the times when it's actually best to be at each place. One trip a month is built in full, for free, up to 12 days.
