Much of this advice assumes you are heading west towards Cornwall.
It is essentially aimed at people flying into Exeter airport. It could equally apply to people taking the train out of London or other parts of the UK.
As with anywhere, a car can give a lot more flexibility, especially as there are many parts of the South West which are extremely rural. However, many of the most impressive destinations in Cornwall in particular are connected to the central spine of the London to Penzance Great Western Railway, and as so many of these routes are scenic, we think the best way to enjoy this part of the world is to do so by train.
