How many days do I need in London?

Four to five days gives you enough time to see the major landmarks, explore a couple of neighbourhoods properly, and leave room for the unplanned afternoon in a pub or park that often ends up being the best part of the trip. You could fill two weeks and still have a list. Three days is doable but you'll be rushing, and rushing in London means spending half your time on the Tube.

Is the London Pass worth buying?

It depends on how many paid attractions you're planning to visit. If you're doing the Tower of London (currently around £33), Westminster Abbey (£27), and a couple of other paid sites in one or two days, the maths might work out. But given that so many of London's best museums are free, a lot of visitors find they don't visit enough paid attractions to break even. Do the arithmetic for your specific itinerary before committing.

Do I need to tip in London?

At restaurants, 10-12.5% is standard, though many places now add a discretionary service charge automatically: check the bottom of the bill. You're within your rights to remove it if service was poor, though most people don't. At pubs, tipping isn't expected if you're ordering at the bar. For black cabs, rounding up to the nearest pound is common but not required. Hotel porters might get a pound or two per bag.

Is London safe for solo travellers?

Generally, yes. The Tube runs late and Night Tube covers several lines on weekends. Most neighbourhoods are perfectly fine to walk around at night. Use normal big-city awareness: avoid unlit shortcuts, keep your phone secure on crowded transport, and maybe skip the very last carriage on late-night trains if it's empty. Solo dining is completely normal here and no one will bat an eye at a table for one.

Should I get an Oyster card or just use contactless?

If you have a contactless debit or credit card that doesn't charge foreign transaction fees, just use that: it's accepted everywhere the Oyster card is, and the daily cap is the same. The main reason to get an Oyster is if your bank charges per-transaction fees abroad, or if you're buying a weekly cap (which requires an Oyster or a contactless card registered to a TfL account). You can buy Oyster cards at any Tube station from the machines.

What's the best way to get from Heathrow to central London?

The Elizabeth line is currently the best option for most people: it takes about 30-40 minutes to reach central stations like Paddington, Tottenham Court Road, or Liverpool Street, and it costs the same as a regular Tube fare if you travel off-peak (around £5.50 with Oyster or contactless). The Heathrow Express to Paddington is faster at 15 minutes but costs £25 unless you book well ahead. The Piccadilly line is cheapest but takes about an hour and the trains don't have luggage space designed for suitcases. Avoid black cabs from Heathrow unless you're splitting the fare: it'll run £60-100 depending on traffic and time of day.

Can I drink the tap water?

Yes, London tap water is perfectly safe and quite good. It's hard water (high mineral content), which some people notice in the taste, but it's rigorously tested and completely fine to drink. Carry a refillable bottle: many cafés and restaurants will fill it for free, and there are an increasing number of public water fountains, particularly in the parks and along the South Bank.

What should I not do as a tourist in London?

Stand on the left side of an escalator. Seriously: stand on the right, walk on the left. Londoners will let you know if you get this wrong. Don't stop suddenly in the middle of a busy pavement, especially on Oxford Street or near Tube exits. Don't eat at the restaurants immediately around Leicester Square: the food is mediocre and overpriced, and there are far better options a five-minute walk in any direction. Don't bother with the big bus tours if you're reasonably mobile: the top deck of a regular London bus gives you the same views for a fraction of the price.

The Thames bends through London in a broad S-curve, and that single geographic fact has shaped nearly everything about the city, which side of the river carries the money, which carries the grit, where the bridges funnel foot traffic into knots of commerce and theatre. Nearly nine million people live here, making it the largest city in Western Europe, and yet London operates less like a single metropolis than like three dozen villages that happen to share a tube map. Your first morning might start in Bermondsey, where railway arches house coffee roasters and cheese caves, and by afternoon you could be standing in the reading room of the British Museum without having paid a penny for admission, because London's national museums are free: a policy that quietly separates it from almost every other capital on earth. The historical arc runs from Roman garrison town to medieval trading port to imperial capital to postwar austerity to the polyglot financial centre it is today, and each era left its residue in the built environment: a fragment of Roman wall near the Barbican, Wren's Portland stone churches rebuilt after the 1666 fire, the concrete Brutalism of the Southbank Centre, glass towers crowding the City and Canary Wharf. Locals navigate by neighbourhood (Hackney, Peckham, Brixton, Camden, Dalston) and each name carries associations about food, rent, music, and who you might run into at the pub. The weather is milder than its reputation suggests; average winter lows sit around four degrees Celsius, and snow is rare enough to shut the transport network when it arrives. What catches first-time visitors off guard is not the grandeur but the granularity: a city this old and this large rewards anyone willing to walk one extra street past the obvious attraction and notice what happens at ground level.
