How long does it take to go from London Heathrow Airport to London Capital.?
You should take the piccadily line (purple) from the heathrow tube station. It would probably take atleast one hour each side to central London depnding on the train traffic and depending on which tube station you want to get off at. And as far as the immigration process is concerned its always unpredictable. Sometimes there are no lines and you go straight away to the immigration officers and sometime there are long queues. This I am talking when you land at Heathrow. And when you come back to the airport from Central London to take your flight there are definitely long queues at the security checks. Be prepared for that. So lets assume 2 hours each side at the security and immigration, 2 hours for the tube travel (assuming you are taking the tube) so 15 hours – 4 hours= 11 hours I think you should have plenty of time to kill in London and even if you loose some time at security or in tube travel then if not 11 then 8,9,10 hours are also sufficient time to explore something in London.
