Acton Town is a London Underground station in the south-west corner of Acton, West London, in the London Borough of Ealing, close to the border with the London Borough of Hounslow. The station is served by the District and Piccadilly lines and is in Travelcard Zone 3.
London is divided into 1–9 zones*, but most of it fits into zones 1–6. Central London is zone 1, zone 2 is the ring around zone 1, zone 3 is the ring around 2 and so on.
Tourists normally use zone 1 where most of the tourist attractions are located, along with a lot of the popular hotel districts. Some of London's trendy neighbourhoods like Camden and Notting Hill are located in Zone 2.
But Zone 2 in East London and South London has some relatively high crime areas, and a significant number of people living in social housing. The best Zone 2 areas are in North London along the Hampstead branch of the Northern Line underground, and the Jubilee line going through St. John's Wood.
Zone 1 covers the West End, the Holborn district, Kensington, Paddington and the City of London, as well as Old Street, Angel, Pimlico, Tower Gateway, Aldgate East, Euston, Vauxhall, Elephant & Castle, Borough, London Bridge, Earl's Court, Marylebone, Edgware Road, Lambeth North and Waterloo.
Most Zone 3 tube stations are 20 to 30 minutes from Central London. Travel from Zone 3 stations in the West London area into Central London takes a bit longer, an hour at the most.
Covent Garden is a London Underground station serving Covent Garden and the surrounding area in the West End of London. It is on the Piccadilly line between Leicester Square and Holborn stations and is in Travelcard Zone 1.
