I live in South West England and my girlfriend lives In Belgium, long story short what's the cheapest way to get there to go visit her?

Train via London interchanging between Paddington or Waterloo and the Eurostar Terminal at London St Pancras International. Book well in advance for the lowest fares. Booking opens 16 weeks ahead of your journey. Through tickets should be available from your local station, but not at the ticket office

Get a computer. Find google search. Check out ticket prices for public transport, different days and times etc.

Bicycle to Dover, ferry to Calais, bicycle the rest of the way.

You asked for cheapest, not for comfortable or easy or quick.

Have you heard of google you could find out in a few minutes

i'd think take a ferry to Brittany and hitchhike from there

Walk and swim

You seem to be stupid
