We are in London at the end of May and want to go out to Duxford.
Which train do we take and which station do we get off at?
Going on a Monday or Tuesday. Taxi availability??
When we visited the museum, we were staying in Cambridge and took the bus part way, as recommended by Rick Steves book (at least at that time). The problem was that the walk from the bus to the museum was not just lengthy (which doesn't bother us) but it was on very well traveled roads with no sidewalk for much of the way. If you can find a train that stops close by and then take a taxi, that would be your best bet I think. We loved the air museum.
