Begin at Tate Modern, which is one of the best possible first stops for a first-time London trip because it’s free, easy to enjoy without rushing, and right on the river. If you’re coming from Casuarina Tree, the simplest route is usually Overground/Elizabeth line or Tube into central London, then a short walk depending on where your hotel sits exactly; in practice, budget about £2.80–£3.50 with contactless/Oyster for the central ride. Give yourself around 1.5 hours to wander the main collections and the Turbine Hall, and don’t stress about seeing everything — this is more of a “land in London” stop than a museum marathon. If you want a coffee before you go in, the Bankside area has plenty of easy options, but the museum itself is the point here: free entry, very walkable, and a brilliant first look at the Thames from this side.
From Tate Modern, walk straight out toward Millennium Bridge — it’s only a few minutes away and gives you one of the classic London views: St Paul’s Cathedral dead ahead, river on both sides, and the city skyline around you. The crossing itself takes maybe 10–20 minutes with photo stops, and it’s one of those “yes, I’m really in London” moments. Continue on foot to St Paul’s Cathedral; this is an easy, pleasant walk and costs nothing extra. For the cathedral, plan on £26 entry (roughly, and worth checking the official site for any updated pricing or last-entry times), with 1.5–2 hours if you want to do it properly, including the dome and Whispering Gallery. It usually opens from morning until late afternoon/early evening, but for a day like this the safest move is to arrive with enough daylight so you can enjoy both the interior and the outside steps without feeling rushed.
For dinner, head to OXO Tower Brasserie on the South Bank — it’s one of the better “special but not ridiculous” first-night choices, and the river views make it feel like a proper arrival dinner. Expect around £40–£60 per person depending on drinks and how much you order; if you want a calmer atmosphere, book ahead, especially on a Friday evening. After dinner, do the Southbank riverside walk to the London Eye area and just let the evening unwind — this stretch is full of street performers, buskers, and that lively London mix of locals, tourists, and people heading out for the night. It’s an easy 30–45 minute wander, fully on foot, and if you need to head back afterward you can pick up the Tube from Waterloo or Blackfriars nearby.
Start your day at Westminster Abbey as early as you can, ideally around opening, because it gets busy fast and the experience is much better before the tour groups in. Entry is about £30 for adults, and you’ll want 1.5–2 hours to do it properly rather than rushing through. If you’re coming from Casuarina Tree, the most straightforward route is usually via Overground/Elizabeth line or Tube into central London, then changing to the District or Circle line to Westminster station; from there it’s a short walk to Broad Sanctuary. Ticket prices vary by route, but with contactless/Oyster, a central zone Tube journey is typically around £2.80–£3.50 depending on time and zones. After the abbey, keep the classic Westminster loop going with a quick exterior stop at Big Ben and the Houses of Parliament — you don’t need long here, just 20–30 minutes for photos from Parliament Square and the river-facing side. From there, walk across to St James’s Park; it’s one of the loveliest short breaks in central London, especially if the weather behaves, and you get that postcard view back toward the government buildings and the palace route.
Continue on foot through St James’s Park and up toward Buckingham Palace (exterior) and The Mall. This whole stretch is best done slowly, because the point is the atmosphere: formal London, but with enough open space that it doesn’t feel exhausting. Expect 30–45 minutes here, more if you stop for photos or a coffee nearby. When you’re ready for lunch, head to Fortnum & Mason Diamond Jubilee Tea Salon on Piccadilly; it’s one of the most classic, polished places in the city for a proper London break without feeling too stuffy. Budget roughly £35–£70 per person depending on whether you go for tea, a light lunch, or something more indulgent. If you want the easiest onward hop, Green Park station is the nearest Tube stop, with Piccadilly, Jubilee, and Victoria lines all useful here.
After lunch, do the pleasant final walk from Piccadilly Circus to Covent Garden. You’ll feel the city shift from grand and ceremonial to lively and theatrical very quickly: bright screens at Piccadilly Circus, then Regent Street, side streets with shops and galleries, and finally the busier, more playful atmosphere around Covent Garden Market and Seven Dials. It’s a good end-of-day area because you don’t need a strict plan — just wander, browse, and maybe stop for a drink or dessert. If you want to head back to Casuarina Tree after that, the simplest return is usually from Covent Garden station on the Piccadilly line, or from Leicester Square if that’s more convenient; again, expect around £2.80–£3.50 on contactless/Oyster for most central journeys.
Start at the British Museum in Bloomsbury as close to opening as you can, ideally around 10:00, because it’s the kind of place that gets much better when you’re not fighting crowds. The permanent collection is free, and for a first visit I’d focus on the big-name rooms rather than trying to “do” the whole building: the Rosetta Stone, the Parthenon Sculptures, the Egyptian mummies, and the central Great Court are the essentials. From Casuarina Tree, the easiest way in is usually Overground or train into central London plus the Tube depending on where you’re staying exactly, but once you’re in the city the cleanest route is Northern line to Tottenham Court Road or Central line to Holborn, then a 10–15 minute walk. Budget around £0 for entry, with special exhibitions extra, and give yourself about 2 hours so you can actually enjoy it instead of sprinting room to room.
From there, walk or hop one stop west to The Wallace Collection in Marylebone; it’s one of the nicest “insider” museums in central London because it feels elegant, calm, and very manageable after the scale of the British Museum. It’s free, housed in a beautiful townhouse, and the rooms are full of French furniture, armour, paintings, and decorative art without the usual museum fatigue. The simplest transfer is a short 12–15 minute walk through Bloomsbury and toward Marylebone, or a quick Tube ride to Bond Street if you’d rather save energy. Plan about 1.5 hours here, and it’s the sort of place where you can slow down and wander without needing a strict route.
For lunch, head to Selfridges Food Hall on Oxford Street—it’s practical, central, and easy, especially if you want to keep the day moving without a sit-down detour. This is not a “destination lunch” in the romantic sense, but it’s ideal on a packed London day: lots of choice, quick service, and good quality. Expect roughly £15–£25 per person, depending on whether you grab something simple or build a more substantial meal. If you want the easiest move from The Wallace Collection, it’s a straightforward walk south to Oxford Street via Marylebone and Bond Street, or a short ride on the Central line to Bond Street and then a few minutes on foot.
After lunch, continue to Madame Tussauds London in Marylebone, which is one of those classic first-time London stops that people either love for the novelty or enjoy simply because it’s such a recognisable part of the city’s tourist circuit. Pre-booking is strongly recommended, and entry is usually around £35–£45 depending on the date and time. Allow about 1.5 hours. It’s an easy walk from Selfridges up to Baker Street, or you can take the Central line to Baker Street and walk from there. Once you’ve had your fill, keep the afternoon gentle with a reset in Regent’s Park—it’s right nearby, and after museums and crowds it’s exactly the kind of green break that makes London feel livable. Stroll through the paths, pause by the flower beds, and if you want a quiet coffee, the area around Baker Street and Marylebone High Street has plenty of good options. Spend 45–60 minutes here before heading into the evening.
Finish in Soho at Dishoom Carnaby, which is a strong choice for a first-time London dinner because it’s central, polished without feeling formal, and genuinely good rather than just “popular.” Booking ahead is wise, especially on a weekend, and you should expect around £25–£40 per person depending on whether you order a full meal with drinks. From Regent’s Park, the easiest route is the Bakerloo line from Baker Street to Oxford Circus, then a short walk through Carnaby into Soho; from Marylebone, a taxi is also a simple late-day option if you’d rather not deal with Tube crowds. Keep the rest of the night loose—this is a good area for a slow walk afterward through Carnaby Street and the surrounding lanes, which gives you a bright, easy London evening without overloading the day.
Start your last day in East London at Liverpool Street Station to Spitalfields Market — it’s an easy, classic London opening and a nice way to feel the city wake up without wasting time. If you’re coming from Casuarina Tree, plan roughly 45–70 minutes depending on the exact hotel location and whether you take a bus, taxi, or train connection; for the smoothest trip, use contactless/Oyster and aim for Liverpool Street. From there it’s a short walk into Spitalfields, where the breakfast energy is best around opening time: think coffee, pastry, and a bit of people-watching rather than a long sit-down meal.
Continue into Old Spitalfields Market, which is one of those places that works best when you just drift. The market itself is free to enter, and on a weekday morning it feels lively without being too packed. Good stops for a light breakfast or snack are the coffee counters and bakeries around the main hall; if you want something more local-feeling, grab a takeaway and browse the stalls rather than sitting too long. Then walk over to Brick Lane, which is really the heart of this East London stretch: street art, vintage shops, and the famous curry-house strip all sit within a very walkable area. You do not need a strict plan here — just wander, look up at the murals, and let yourself be pulled along by the side streets. A good London-style transit note for the whole morning: once you’re in this area, you can do nearly everything on foot, and if you need to hop farther, Liverpool Street and Aldgate East are the most useful Tube stations.
From Brick Lane, make your way to the day’s main historic stop, Tower of London, via Aldgate East or Liverpool Street and then the Tube to Tower Hill; the simplest route is usually one quick Underground ride plus a short walk. This is the big-ticket attraction of the day and worth giving real time to: allow about 2 hours for the Tower of London, with entry around £34.80 for adults. Go for the Crown Jewels, the medieval towers, and the riverside views, but don’t rush the grounds — the atmosphere is half the point, especially on a first London trip. After that, walk straight over to Tower Bridge Exhibition, which is the perfect pairing and just a few minutes away on foot. Entry is around £16.00, and the high-level walkways are excellent for photos and for seeing the river, the City, and the Tower together from above. If you want the cleanest route between the two, stay on the riverside paths and follow the signs; you’ll barely need transport at all.
Wrap up with Lunch at Bodean’s Tower Hill, which is a very practical final stop before heading toward Luton Airport. It’s close enough that you won’t stress about timing, and the pricing is generally around £20–£30 per person depending on what you order. If you want to keep it efficient, go for something filling and not too messy, then leave yourself time for the transfer. From Tower Hill, head back to Luton Airport by making your way to St Pancras International for the Luton Airport Express from Luton Airport Parkway; the airport shuttle from the terminal to the station is typically included with rail tickets. Budget roughly £12–£25 one way if booked ahead, more if you buy late, and give yourself a comfortable buffer — London transfers are usually straightforward, but returning on the same day is much nicer when you’re not watching the clock too hard.
