It is still possible to hitch-hike, although I wouldn't recommend it. It really depends on where you're trying to travel, how long you have and your own psyche.

Inter-railing is the obvious choice; if you're going to a lot of locations throughout Europe the passes run on trains throughout most of Western Europe and lots of Central/Eastern countries too. There are discounts for under-26-year-olds as well.

If you're looking for only a few journeys, then I'd also consider looking into the no-frills airlines. There are far, far too many for me to list them here, but beware- you must book *months* in advance. Book for the same week and it's actually much more expensive than a flight from a 'flag carrier' airline!

Finally, be aware that flying is often cheaper than trains- in the UK particularly. BA now offers European flights for about £60 all-in; Aer Lingus has £40 return London to Dublin. My train fare to York from London was £70, bought in advance and with a 1/3 discount for being young...

Hope you enjoy your trip!
