Day trip from London to Windsor: how to get there and what to do

Windsor works as a day trip because the travel is short and the main sight is compact. Windsor Castle sits at the top of the town, St George's Chapel is inside the same walls, and the Long Walk runs straight from the castle gate for 4 km toward the Copper Horse. You can see the core of it in a day and be back in London for dinner.

It is a weaker choice if your London time is short. Two days in London is not enough to give one away. It is also weaker if you want countryside: Windsor is a town with a royal park attached, not a village. Travellers who want a slower day with more walking usually do better at Cambridge, Oxford or Brighton.

The day trip pays off most for first-time visitors with an interest in the monarchy, for families who want one easy outing, and for anyone staying near Waterloo or Paddington. It also pairs well with Eton, a 15-minute walk across the bridge, or with a Legoland visit if you have children.

Two train routes serve Windsor. From London Waterloo, trains run to Windsor & Eton Riverside; from London Paddington, take a train to Slough and change for the short branch to Windsor & Eton Central. Both routes take roughly 30–60 minutes depending on the service and the connection. Check the day's timetable before you go, because Sunday and engineering works can change the pattern.

Coaches from London Victoria to Windsor take longer, roughly 45–90 minutes, and are usually the cheapest option if you book ahead. They are more exposed to traffic, so avoid them on a weekday morning if you have a timed castle ticket.

Driving is the least attractive option for a day trip. Windsor has parking but it fills on weekends and school holidays, and the town centre has restricted access. If you drive, use a car park on the edge and walk in.

Guided tours from London exist and bundle transport with a castle ticket. They cost more than doing it yourself but remove the planning, which suits a first visit or a short stay.

Leave London around 08:30 so you reach Windsor before the castle opens. Walk up to the castle first: security queues build through the morning, and the State Apartments and St George's Chapel are the reason most people come. Allow two to three hours inside, more if you join a guided tour of the precincts.

After the castle, walk down to the High Street for lunch, then cross Windsor Bridge to Eton for a look at the college and the river. Come back along the Thames Path, or take the Long Walk if the weather is good. Finish with a drink in town before the train back, aiming to leave Windsor between 17:00 and 18:00 to miss the worst of the evening crush.

If you have children and a full day, Legoland Windsor is a separate day in itself and does not combine well with the castle. If you are there on a day when the Changing of the Guard happens at Windsor, plan around it: it draws crowds and changes the castle flow.

The day is dominated by two costs: transport and the castle ticket. Advance train tickets are much cheaper than walk-up fares, and coaches undercut both. Castle entry is the single biggest item; check the official price for your date, because it changes and peak days cost more.

Food in Windsor is priced for visitors. A pub lunch or a sandwich from a shop keeps the day cheap; a sit-down meal near the castle pushes it up. Budget a little for a drink or an ice cream on the Long Walk in summer.

A realistic total for one adult doing it independently, with an advance train ticket, castle entry, lunch and a coffee, sits in the region of £50–80 (about US$65–100) in 2026. A guided tour from London usually costs more but includes transport and entry.

For most travellers, no. Windsor is close enough that an overnight adds hotel cost without adding much. The case for staying is specific: you want the castle at opening without an early train, you are combining Windsor with Legoland, Ascot or a Thames walk, or you are ending a trip near Heathrow and want one calm night before flying.

If you do stay, book early for weekends and race days, when prices in the town jump. Hotels near the castle and along the river are the most convenient; Eton and the outskirts are cheaper. Windsor also works as a base for a Heathrow departure, since the airport is a short taxi or bus ride away.

Windsor & Eton Central and Windsor & Eton Riverside stations are both within a 10-minute walk of the castle. The castle, the High Street, Windsor Bridge and the start of the Long Walk are all in the same small area, so you do not need transport inside the town.
