Heathrow to Holborn

There are various options, but in the absence of any other information about you and your trip (such as time of arrival, how many in your party, how much luggage, your age and mobility including your ability to deal with steps and escalators with luggage), I'll just mention the simplest and cheapest.

That's the London Underground, also known as the Tube. The Piccadilly line starts at Heathrow and runs direct to Holborn in about 50 minutes with no changes, then it's a 5 minute walk to Boswell Street.

Buy Oyster cards at the Tube station at Heathrow, because you'll need them for travelling around London while you are here. These are plastic "smartcards" which you top up with cash, then touch in and out on special sensors at Tube stations and on buses, which automatically deducts the cost. Cost with an Oyster card outside of peak hours (after 09.30 and before 15.59) is £3. The cash fare without an Oyster card is £5.50.

There are other options, and I'm sure other helpline members will be along presently to describe those, or you can look at this page on the Heathrow website - http://www.heathrowairport.com/transport-and-directions

Thanks Kevin. Looks like the Tube is the way to go. Thanks for the Oyster Card info. I will be getting those as well.

I stayed right by the Holborn stop recently. The Picadilly line is the cheapest and easiest way to get there from Heathrow. If I remember correctly, you have to walk up about 12 steps once you get out at the tube platform, then catch the escalator to street level. It also has a manned ticket office in case you need to talk to a "real" person for assistance.

Depending on which end of Holborn you are on and if you'd still have to walk with your luggage from the Tube station, you could do the Holborn Tube or Russell Square. I think there are a few steps in to the Russell Square Tube, but there are elevators there for the rest of the way. I find that taking the Tube is cheaper and easier, but just keep in mind that you may be leaving with more stuff than you came with--making it hard to get your gear in and out of the station. And that sometimes the trains going out to the airport are incredibly slow. I don't know if it was an issue on that day, but I honestly thought I could walk faster. Always leave extra time, even if the trip from central London takes only 45 minutes or whatever it may be. Enjoy!
