Sorry, I cannot remember. We visited IWM Duxford just once, and drove along the road, but that is all I can remember. Duxford was`well worth visiting, and one of the main reasons we stayed in the area for a few days.

We traveled by train from London Liverpool Street station to Whittlesford Parkway station (Duxford) in early January 2017. This is the closest station to IWM Duxford. It's about a 2 mile walk, and there are footpaths / sidewalks the entire route, even though parts are along a busy road. It was about a 30 minute walk for us, and totally worth it. Far easier, and cheaper, than relying on bus or taxi.
