By train
Eurostar (http://www.eurostar.com/d...) links mainland Europe to England. Trains run from Paris, France and Brussels, Belgium via Lille and Calais crossing into England via the Channel Tunnel and often stopping at either Ebbsfleet or Ashford before continuing to St. Pancras Station in London. Occasional services run from other destinations in France. Book as early as possible as fares can be considerably more expensive if trying to book at the last minute.
From Wales and Scotland regular services cross the borders into England.
BritRail Passes are also available to non-UK citizens which allow the traveller unlimited rail travel in England on one ticket (http://www.britainontrack.com). Wikitravel has a guide to Rail travel in the United Kingdom.
