No, you cannot visit Paris on UK visa. On UK visa you can travel to Scotland, Wales and Northern Ireland. You need to have Schengen Visa to travel to Paris, which is part of France.

No, in 2026, Paris is not included in a UK visa, and vice-versa. Because the United Kingdom is not part of the Schengen Area, a UK Standard Visitor Visa only permits travel within England, Scotland, Wales, and Northern Ireland. To visit Paris, which is in France, you must comply with Schengen Zone regulations. If your nationality requires a visa for Europe, you must apply for a separate Schengen Visa. Furthermore, by 2026, even visa-exempt travelers (like those from the US, Canada, or Australia) must have an approved ETIAS (European Travel Information and Authorisation System) to enter France, while also needing an ETA (Electronic Travel Authorisation) to enter the UK. When traveling from London to Paris via the Eurostar train, you will go through two sets of border controls at the station (St. Pancras or Gare du Nord): one to exit the UK system and one to enter the French/Schengen system, as they remain entirely distinct legal and political jurisdictions.
