Everybody knows you can get Paris breaks from St Pancras Station in London, and some that you can also catch the Eurostar at Ebbsfleet and Ashford but not much has been written about the new Straford International Eurostar station in East London. That's because of the 2012 Olympics probably, which delayed the opening of this new intersection transport hub. Stratford International was in fact built at the same time as the fast high speed link from St Pancras to the channel tunnel, but it couldn't be opened straight away because of the work surrounding the site for the London Olympics in 2012.
But now Stratford is open, you just have to get a special bus service through the building site, from Stratford mainline railway station, platform 11. The Eurostar trains themselves, from St Pancras, don't stop at Stratfrd International yet, and there is still some dispute as to whether the London to Paris trains will stop at Stratfrd during and after the Olympics, but the high speed South Eastern trains service does stop at Stratford, so you can take a very fast train from Stratford to Ebbsfleet, Ashford and then on to Dover or Canterbury or use this route to connect with the Eurostar.
