Windsor doesn't have an underground station itself, with London Paddington Station the closest to the area. However, if you want to travel using the Tube, you can take the metro to London Paddington station and transfer to a train going to Windsor & Eton Central Station.

No, the London Underground (the Tube) does not go all the way to Windsor Castle, as Windsor is located in the county of Berkshire, outside of the standard Transport for London (TfL) fare zones. To reach the castle from central London, you must take a National Rail train. There are two primary routes: you can take a fast train from London Paddington to Windsor & Eton Central (changing at Slough), which takes about 30–35 minutes, or a direct train from London Waterloo to Windsor & Eton Riverside, which takes about an hour. While you can use your Oyster card or Contactless payment to travel as far as West Drayton or Slough on the Elizabeth Line or GWR, you generally need a separate National Rail ticket to complete the journey to Windsor. Some "Windsor Express" bus services also run from Victoria, but the train remains the most reliable method. If you are already on the Tube, you would typically take the District or Circle line to Paddington or the Jubilee/Northern line to Waterloo to catch your connecting train to the castle.
