15 Free Things to Do in London: Museums, Parks & More

Anything made of open public ground or public water works on this list: squares, parks, riverside paths, outdoor markets, and the ceremonial bits of royal life that play out in the street. Anything with a roof, a turnstile, or a timed slot usually does not, and the London Eye sits firmly on that side of the line.

The fifteen stops break down like this.

• Three museums and galleries. The British Museum, Tate Modern and the Victoria and Albert Museum, all on the same walking line as the river.
• Four parks. Hyde Park with the Serpentine, Richmond Park, Greenwich Park and Regent's Park, a stretch of open ground the city leaves open.
• Four riverside and square stops. The South Bank, Big Ben, Parliament Square with Downing Street, and the Tower Bridge waterfront.
• Four ceremonies and markets. The Changing of the Guard, Borough Market, the Oxford Street lights and the Trafalgar Square tree.

That is fifteen ways to spend a day, and the sequence matters more than the list itself.

Three collections carry most of London's indoor sightseeing, and all three open their permanent rooms to the public. Special exhibitions inside them are ticketed, so treat those as a separate decision from the walk through the building.

The British Museum

This is the collection people build a whole morning around, and the permanent rooms reward a slow walk. Give it two to three hours rather than a rushed forty minutes, because the building spreads across several floors and the walk between galleries is half the visit. Arrive when the doors open and you get the quiet rooms before the school groups do.

Tate Modern

Tate Modern is the modern one, and the general collection stands right beside the South Bank walk, which makes it the natural companion to the river rather than a separate trip. It suits an afternoon when the weather turns. Allow ninety minutes if you are picking highlights, a full afternoon if modern art is your thing.

The Victoria and Albert Museum

The Victoria and Albert Museum is the one to save for a cold afternoon, when a slow walk through its rooms beats standing at a bus stop. Decorative arts, costume and design fill the halls, and the main rooms reward a slow lap. Two hours covers the main rooms at an easy pace, and the museum stands close enough to Hyde Park that you can move between indoor and outdoor sightseeing without losing the afternoon to travel.

Pick one of the three for a single day, not all three. Each of them rewards slow walking, and three in one afternoon turns sightseeing into a march.

London's parks are the reason a day on foot works at all. They sit inside the transport network rather than out at the edge of it, and they give you somewhere to sit down between museums.

Hyde Park and the Serpentine

Hyde Park splits around the Serpentine, the long lake that runs through the middle, and the circle around that water is what locals walk on a Sunday. In autumn, the tree-lined avenues near the lake turn gold, and the light late in the afternoon is the softest you will get in the city. Take a coffee, follow the loop, and give it ninety minutes.

Richmond Park

Richmond Park is the big open one, the widest skyline on this list, and it is where the autumn crowds go for the turning foliage. If your trip lands in October or November, put this park first rather than last. Getting there and back takes half a day, so plan it as the main stop instead of fitting it around two others.

Greenwich Park

Greenwich Park is the summer one, where the picnics spread out and people linger past sunset. It sits close to the river, so you can pair it with the riverside walk back toward the centre and keep the whole day on foot. Give it two hours and give it the end of the day rather than the start.

Regent's Park is the fourth on the list and the easiest to fold into a West End evening, because it sits close to the theatre district and takes you across open ground after a show.

If the weather turns against you, swap the park for the museum and keep the day moving. Which of the two you pick matters far less than standing in the rain.

Some of the best views in London come from public ground you can stand on. The river ties three of these stops together, and all three work on foot.

The South Bank and the River Thames

The South Bank walk follows the River Thames past the stretch that turns up in every photograph of the city, and the path itself is open ground. Start near the London Eye; note that the ride itself is a ticketed attraction, then keep heading east as the river carries you along. Two hours at a stroll, longer if you stop on the way.

Westminster: Big Ben, Parliament Square and Downing Street

Walk from Trafalgar Square into Westminster, and you get the government quarter of the city on foot. Big Ben, Parliament Square and Downing Street are all outside on the street, all seen from the pavement, and all within a fifteen-minute walk of one another. Westminster Abbey stands on the same route, and it is the stop to decide about in advance if you want to go through the doors.

Tower Bridge and the Tower of London from the Riverbank

Come back to the water in the late afternoon for Tower Bridge, which looks best once the light drops and the lamps come on. The bridge and the waterfront hand you that view from the bank, and the walk along the water is where the photographs happen. The Tower of London next door keeps the crown jewels inside, so treat it as its own plan rather than part of the riverside afternoon.

If you would rather not read a bus map between stops, a London tour can fold the riverbank, the Westminster stretch and Trafalgar Square into one afternoon and leave your evening open.

The last group is what turns a day on foot into a day rather than a walk. Ceremonies, markets and seasonal lights all play out in the street, and they put you among Londoners instead of beside them.

The Changing of the Guard at Buckingham Palace

The Changing of the Guard is the set piece, a display of pageantry and military drill outside Buckingham Palace that draws a crowd whenever it runs. Watching from the railings is how most people see it, and arriving early is the difference between watching it and hearing it from three rows back. Give it forty minutes, then walk the length of the palace front, where the lavish rooms and the Royal Gardens sit inside and ask for their own visit.

Borough Market

Borough Market is the market stop, and walking through it is the point. The stalls sell food and drink; the seasonal dining around it is why locals keep coming back, and you can take as long as you like between the tables. Come hungry, give it ninety minutes, and count lunch as the one thing you actually pay for that afternoon.

The Oxford Street Lights and the Trafalgar Square Tree

From late November, the city switches on its Christmas lights along Oxford Street, which are best seen on foot after dark. The decorated tree in Trafalgar Square arrives around the same time, and both sit within a short walk of the West End, where the theatre season opens for anyone who wants to pay for an evening out.

So which of the three should you plan the day around? The ceremony depends on the day you visit, the market keeps its own hours, and the lights are seasonal. In summer, swap the last one for a long evening in Regent's Park and keep the day on foot either way.

Now the honest part. A day of walking still moves you around a very large city, and the moving itself is where the money goes. So what does the day actually ask you to pay for?

The Tube, the buses and the trains are how you get between these stops, and they run on contactless payment: a bank card, a phone wallet or an Oyster card you load in advance. Buses do not take cash, so turn up with a card or a topped-up Oyster and skip the queue at the machine. Daily fare caps keep a long day of hopping on and off from running away with your budget, and the same system covers the Underground, the buses, the Docklands Light Railway and London Overground.

Cash still has a place, just a smaller one than most visitors expect. Keep a little for market stalls and small cafes, and let the card handle the transport.

Then come the paid stops. The headline exhibitions inside the three big museums are ticketed, and the London Eye is a ticketed attraction too. Budget for one or two of those if they matter to you, and let the rest of the day stay on foot.

If you are building a longer stay around these walking days, London vacation packages roll the hotel and the transport into one booking, which keeps the mornings open. Tours4fun sells the day trips and the paid stops alongside them, so the days you plan on foot can stay exactly as you planned them.

With one day, this is the loop that works. Start at Trafalgar Square, walk into Westminster for Parliament Square and Big Ben, catch the Changing of the Guard if the timing lines up, then follow the river east to Borough Market for lunch. The squares, the ceremony, the water and the market all fit inside one loop.

With two days, add a single museum on the second morning rather than three, then spend the afternoon in Hyde Park walking the Serpentine. The parks and the river are what make the day feel like London instead of an itinerary.

Three days is where the list starts competing with itself, and that is when you choose which stops are worth the travel. Keep the British Museum and the South Bank walk close together, and drop Richmond Park unless you have half a day to spare, because the trip out there eats the hours you wanted for the river. If green space is the whole point of your trip, do the reverse: build the day around Richmond Park or Greenwich Park and cut the museums instead. Everything on this list works on foot, but your time does not stretch, so spend it on the stops you will actually remember.
