Windsor Castle Tour from London

Windsor Castle is not a museum piece. It is the oldest and largest occupied castle in the world — founded by William the Conqueror in the decade after 1066, home to 40 monarchs since, and still an official residence of the King today. That last fact is the single most important thing to understand when planning a Windsor Castle tour, because a working royal palace keeps a working royal diary: the castle closes to visitors when the diary demands it, sometimes at very short notice.

The schedule trap: check before you travel

Windsor Castle normally opens Thursday to Monday and closes every Tuesday and Wednesday for most of the year (Tuesdays are added back in July, August, and September). Hours run from 10:00 to 17:15 between March and October (last admission 16:00) and 10:00 to 16:15 from November to February (last admission 15:00). On top of that fixed pattern, state ceremonies and royal events can close all or part of the castle with little warning — the Royal Collection Trust publishes a closure list, and it is worth checking rct.uk in the week before you visit, whichever way you book.

Two more scheduling details catch people out. St George’s Chapel is closed to visitors on Sundays — it is a functioning church holding services, so if the chapel is a priority (for most visitors it is), avoid a Sunday visit. And the Changing of the Guard at Windsor takes place on Tuesdays, Thursdays, and Saturdays at 11:00, with the month’s dates confirmed by the British Army around the 20th of the preceding month and the ceremony scaled back or cancelled in bad weather. If you want the full spectacle, aim for a Thursday or Saturday — those days combine an open castle with a scheduled guard change for most of the year.

What actually deserves your time inside

Allow two to three hours inside the walls. The State Apartments are the headline — ceremonial rooms still used for state visits and investitures, hung with Holbein, Rubens, and Van Dyck from the Royal Collection. St George’s Chapel is the other essential: one of the finest Gothic churches in England, begun under Edward IV in 1475, burial place of 11 monarchs including Henry VIII and Charles I. Visitors can also see the ledger stone of the King George VI Memorial Chapel, where Queen Elizabeth II was laid to rest alongside her parents and Prince Philip. Between the two, Queen Mary’s Dolls’ House — a 1:12-scale masterpiece with working lifts and electricity — is a short, worthwhile queue.

Outside the ticketed precinct, walk to the foot of the Long Walk, the tree-lined avenue running dead straight from the castle gates toward the Copper Horse statue in Windsor Great Park. It is free, it is the best photograph in town, and most coach-tour passengers miss it because they don’t budget the fifteen minutes it takes.

Train on your own vs. a coach tour

Getting to Windsor independently is genuinely easy, and an honest guide should say so. From London Paddington, trains reach Windsor & Eton Central in roughly 25–35 minutes with a quick change at Slough; from London Waterloo, a direct service runs to Windsor & Eton Riverside in around an hour. Buy the castle ticket separately from Royal Collection Trust — £32 in advance, £36 on the day for adults — and you have a self-made day trip.

So why book a tour? Three practical reasons. First, the logistics compress: a half-day coach tour like the featured one departs near London Victoria, includes the ride both ways, and packages the timed castle entry and audio guide so nothing needs booking separately. Second, the schedule risk shifts to the operator — if the castle amends hours, the tour adjusts. Third, time economics: with about 2.5 hours on site you see the castle properly and are back in London by late afternoon, which matters on a short trip. The trade-off is flexibility — independent travellers can linger in Windsor town, walk the full Long Walk, or stay for evensong at the chapel. Neither option is wrong; they solve different problems.

Should you combine Windsor with Stonehenge, Oxford, or Bath?

The most-booked Windsor products from London are actually combination day trips — Windsor plus Oxford and Stonehenge, or Windsor plus Stonehenge and Bath. They are efficient samplers: three landmark stops in a single ten-to-eleven-hour day, with entry logistics handled. The honest caveat is depth — a combo typically gives Windsor around two hours, enough for the State Apartments and chapel at a brisk pace, but not much more. If the castle itself is your reason for coming, take the dedicated half-day tour or go by train and give it the full morning. If you want the greatest-hits sweep of southern England in one day — and Stonehenge is otherwise hard to reach without a car — a combo is the right tool; our comparison table above breaks down the options, and for the stone circle specifically see the dedicated Stonehenge tour from London guide.

However you visit, remember what makes Windsor different from every other castle tour in Europe: the Royal Standard flying from the Round Tower means the King is in residence. You are not touring a relic — you are a guest at a house that has been doing its job for a thousand years.
