London is one of the most visited cities on Earth, and for good reason. It has world-class museums, centuries of history layered beneath a modern city, neighborhoods that each feel like distinct villages, and a food scene that has shed its grey reputation entirely.
My wife and I are visiting London in September 2026 and have spent a lot of time researching this trip. Everything in this guide reflects what we've personally looked into: where to go, what's actually worth it, and how to avoid the obvious tourist traps. We'll update this page with firsthand observations after the trip.
This guide focuses on the unmissable experiences, the neighborhoods worth exploring, the free things that rival anything you'd pay for, and the practical information you need to navigate the city without overspending.
1. The British Museum
One of the greatest museums in the world, and entry is free. The British Museum holds over 8 million objects spanning 2 million years of human history, from the Rosetta Stone to the Elgin Marbles to the Lewis Chessmen.
Must-see rooms:
- Room 4: Rosetta Stone, the key that unlocked ancient Egyptian hieroglyphics, on display since 1802.
- Rooms 17–19: Elgin Marbles (Parthenon sculptures), the most contested artifacts in the museum, originally from the Parthenon in Athens.
- Room 41: Sutton Hoo helmet, one of England's most iconic artifacts: a 7th-century Anglo-Saxon burial helmet found in Suffolk.
- Room 62: Lewis Chessmen, 12th-century chess pieces carved from walrus ivory, immortalized in Harry Potter.
- The Great Court: Sir Norman Foster's stunning glass-roofed courtyard, the largest covered public square in Europe.
Tip: Allow 3–4 hours for a serious visit. The museum is enormous and genuinely impossible to see in one day. Book a timed entry online (free, but it helps manage capacity). Tuesday through Thursday mornings are the quietest.
2. Tower of London & Tower Bridge
The Tower of London is a 950-year-old fortress, palace, and prison that served as the stage for much of English history. It houses the Crown Jewels (including the Cullinan I, the largest diamond ever set in a crown at 530 carats) and the famous Yeoman Warder "Beefeater" guides who give excellent free tours.
What to see:
- Crown Jewels: the line moves quickly, so arrive early or late in the day. The Imperial State Crown, Sovereign's Orb, and Sceptre are extraordinary.
- Yeoman Warder tours, free with admission. The Beefeaters are genuinely entertaining storytellers.
- The White Tower, the original 1078 Norman keep at the center of the complex, containing the Line of Kings armour display.
- Ravens: per legend, if the ravens ever leave the Tower, the Crown and kingdom will fall. Six ravens are kept here at all times.
- Tower Bridge, directly adjacent and worth crossing. The walkway tour (separate ticket, ~£12) takes you across the high-level glass floor with views of the Thames.
Practical: Tickets are £34 for adults online (£38 at the gate). Book in advance. Allow 3–4 hours for the full complex.
3. Borough Market & Southwark
Borough Market is London's oldest and best food market, operating continuously since at least the 12th century. It's genuinely one of the best food experiences in the city, with produce, charcuterie, cheese, bread, and prepared food from dozens of vendors.
While you're in Southwark:
- Borough Market, open Monday through Saturday. Thursday to Saturday is when it's at its fullest. Arrive hungry and graze your way through.
- Tate Modern, a 10-minute walk along the Thames. One of the world's great modern art museums, in a converted power station. Free.
- Shakespeare's Globe, the reconstruction of Shakespeare's original theatre, with tours available year-round and open-air performances from April through October.
- The Shard, Europe's tallest building, offers views from 244 meters. Tickets are expensive (~£32) but the view on a clear day is exceptional.
- Southwark Cathedral, one of London's oldest Gothic buildings (parts date to the 13th century), free to enter, and rarely crowded.
4. Hyde Park & Kensington
Hyde Park is London's most famous park: 350 acres in the middle of the city, with a lake (the Serpentine), rowboat rentals, the Albert Memorial, and Speakers' Corner, where anyone can give a public speech (a tradition since 1872).
What's in the area:
- Kensington Palace, the official residence of several royals including King Charles before his accession. Public areas with royal history exhibitions open daily (~£25).
- Natural History Museum, one of the finest natural history museums in the world: the blue whale skeleton, dinosaur hall, and earthquake simulator. Free.
- Victoria & Albert Museum, the world's largest museum of art and design, covering fashion, furniture, textiles, ceramics, and architecture across 5,000 years. Free.
- Science Museum, excellent for families and genuinely interesting for adults. The space and technology galleries are highlights. Free.
- Harrods, the most famous department store in the world. Worth walking through even if you don't buy anything. The food halls on the lower ground floor are spectacular.
5. Tate Modern & the South Bank
The South Bank is London's cultural spine: a walkable riverside strip from Tower Bridge west to Waterloo that takes in the Tate Modern, Shakespeare's Globe, the Southbank Centre, the National Theatre, and the BFI.
The Tate Modern holds the UK's national collection of modern and contemporary art (Picasso, Warhol, Rothko, Hockney) in a converted Bankside Power Station. The permanent collection is free; major temporary exhibitions charge admission. The Tanks (converted oil tanks in the basement) host performance and installation art.
The walk:Starting at Tower Bridge and walking west along the Thames to Westminster Bridge takes about 90 minutes and passes most of the South Bank's highlights. It's arguably the best free walk in London.
6. Greenwich & the Royal Observatory
Greenwich is one of London's most rewarding half-day trips: a UNESCO World Heritage Site with the Cutty Sark clipper ship, the National Maritime Museum, the Royal Naval College, and the Royal Observatory sitting on the hill above.
Greenwich highlights:
- The Prime Meridian: stand with one foot in each hemisphere at the line of 0° longitude. The Observatory charges for admission (~£18) but the park view of London is free.
- Cutty Sark, the world's last surviving tea clipper (1869), raised above ground on a glass base. Tickets around £18.
- National Maritime Museum, the world's largest maritime museum. Includes Turner's 'Battle of Trafalgar' and Nelson's bullet-pierced uniform. Free.
- The Old Royal Naval College, Sir Christopher Wren's masterpiece. The Painted Hall (London's Sistine Chapel) reopened after a major restoration. Free to enter.
- Greenwich Market, Thursday through Sunday, with food, antiques, and crafts.
Getting there: The Elizabeth line to Canary Wharf then the DLR to Cutty Sark takes about 35 minutes from central London. Or take the Thames Clipper river boat from Embankment for scenic views along the way.
7. West End & Covent Garden
The West End is London's theatre district and one of the two greatest theatre scenes in the world (alongside Broadway). With over 40 major theatres within walking distance of each other, a West End show is one of the experiences that makes London worth the trip.
Theatre tips:
- Book online in advance at the official theatre or Ticketmaster. Avoid third-party resellers.
- TodayTix and the TKTS booth in Leicester Square sell same-day discounted tickets (up to 50% off) for many shows.
- The National Theatre on the South Bank runs world-class productions at slightly lower prices than West End musicals.
- Shakespeare at the Globe (April through October) offers standing 'groundling' tickets for £5, the cheapest and most authentic way to see Shakespeare in London.
Covent Garden is a 5-minute walk from the West End theatres: a Victorian market hall with street performers, independent restaurants, and the London Transport Museum. It's touristy but genuinely enjoyable.
8. Notting Hill & Portobello Road Market
Notting Hill is one of London's most photogenic neighborhoods, with pastel-painted Georgian townhouses, independent bookshops, and Portobello Road Market stretching for almost a mile on Saturdays.
In the area:
- Portobello Road Market (Saturday is the main day): antiques, vintage clothing, produce, and street food. Arrive early for the best antiques.
- Books for Cooks, one of London's best specialist bookshops, dedicated entirely to cookbooks. The tiny kitchen at the back serves lunch.
- Electric Cinema, one of London's oldest cinemas (1910), with armchairs and in-seat food service. An experience beyond just watching a film.
- Ledbury Road, the upscale end of Notting Hill, with excellent independent restaurants and boutiques.
- Carnival (August Bank Holiday): if you're in London in late August, the Notting Hill Carnival is the largest street festival in Europe. Loud, packed, and unforgettable.
Day Trips from London
London sits at the center of England, making it an excellent base for day trips to some of the country's most famous destinations.
Windsor Castle (40 min by train)
The largest and oldest occupied castle in the world, and the King's weekend residence. The State Apartments, St George's Chapel, and the changing of the guard make for a full day. Trains from London Paddington or Waterloo.
Stonehenge & Bath (2 hrs by train)
Often combined as a day trip. Bath is a perfectly preserved Georgian city with Roman baths (the city's namesake) and the Royal Crescent. Stonehenge is a 30-minute bus from Salisbury. Trains from Paddington to Bath take 1h 20m.
Oxford (1 hr by train)
The university city with 38 colleges, the Bodleian Library, and the Ashmolean Museum. Christchurch College inspired Hogwarts. Trains from Paddington run every 30 minutes.
Cambridge (50 min by train)
The punting capital of England. Rent a flat-bottomed boat and push yourself along the Backs (the river behind the colleges) past King's College Chapel. Trains from King's Cross.
Cotswolds (2 hrs by car or tour bus)
Rolling hills and honey-stone villages: Bourton-on-the-Water, Burford, and Stow-on-the-Wold. No easy direct public transport; best done by rental car or a guided day tour from London.
Getting Around London
London has one of the most comprehensive public transport systems in the world. Here's how to use it without overpaying.
Contactless payment (recommended)
Tap in and out with your contactless credit or debit card. Daily and weekly caps apply automatically, so you won't pay more than £8.10 in Zones 1–2 regardless of how many journeys you take. Works on Tube, buses, Overground, Elizabeth line, and DLR.
The Tube (Underground)
The world's oldest metro, with 11 lines covering most of London. Zones 1–2 cover almost everything tourists want to see. Off-peak fares (after 9:30 AM on weekdays and all day weekends) are lower.
Buses
Slower than the Tube but far more scenic, and you can see the city while you travel. All buses are cashless — tap with contactless or Oyster. Night buses (N routes) run through the night when the Tube stops.
Elizabeth line
London's newest and fastest line (opened 2022), running east-west across the city from Reading to Shenfield. Heathrow Airport to Bond Street in 32 minutes. Highly recommended for airport transfers.
Taxis and Uber
Black cabs are expensive but reliable and can legally be hailed on the street. Uber and Bolt are available across London and significantly cheaper. Avoid taxis for long journeys during rush hour.

▶How many days do you need in London?
Three to four days covers the main highlights: the British Museum, Tower of London, Borough Market, Hyde Park, and a few galleries. Five to seven days lets you explore neighborhoods properly, add day trips to Windsor or Stonehenge, and catch a West End show. London rewards slow exploration, and the more time you have, the better.
▶Is London expensive?
London is one of Europe's most expensive cities, but it's more manageable than its reputation suggests. Many of the best attractions are free (British Museum, National Gallery, Tate Modern, Natural History Museum, V&A). Food costs range from £5 for a meal at a market stall to £25+ at a mid-range restaurant. Budget £100–150/day including accommodation, transport, and one paid attraction. Avoid taxis and use the Tube or buses.
▶Is the Oyster card still the best way to get around?
For most visitors in 2026, a contactless bank card (credit or debit) is now the easiest option. The same capped daily fares apply automatically, and you don't need to buy an Oyster card. An Oyster card still makes sense if your bank charges foreign transaction fees. The Tube, buses, Overground, and Elizabeth line all accept contactless.
▶When is the best time to visit London?
London is a year-round city. May and September are the sweet spots, with decent weather (15–20°C), fewer summer crowds, and lower hotel prices than July–August. Summer (June–August) is the most popular time but also the most expensive and crowded. Winter (November–February) has the lowest prices, shortest days, and highest chance of grey weather, but Christmas markets and New Year's are worth it.
▶Do I need a visa to visit London?
US, Canadian, Australian, and most EU citizens can visit the UK visa-free for up to 6 months under post-Brexit rules. However, from early 2025, travelers from many countries need to apply for an Electronic Travel Authorisation (ETA) before arriving, similar to ESTA for the US. Check the UK government's official website for the current list of countries that need an ETA.
▶Is London safe for tourists?
London is generally safe for tourists. Petty theft (particularly phone snatching by moped riders in busy areas) has increased in recent years. Keep your phone in your pocket or bag when not in use, especially on Oxford Street, in crowded markets, and near tourist attractions. The Tube is safe at most hours.
▶Does my phone work in London?
The UK has excellent 4G and expanding 5G coverage across London. Most international roaming plans charge $10–12/day. A travel eSIM for the UK gives you far better value, with plans starting around $4–5 for 1 GB and unlimited data options available for longer stays from providers like Airalo, Saily, and Holafly.
