We are a couple travelling to a house swap in Pau from Northern Ireland in July 2007. We want to find the best way to go, and would like to fade our carbon footprint a bit by trying the train, if it is not too awkward. We could get to London by bus or train and ferry and transfer from there if necessary.If this looks impossible we will try planes but it looks as though this may involve flying Dun=blin or Belfast to Stansted and then Ryanair to Pau airport. Any ideas?
