I'm quite a light packer at the best of times but I still think I over-packed when I went Interrailing. So rather than tell you what I did bring, I'll tell you what I WISH I'd brought instead. You can learn from my mistakes, as there are some things you might take but never need, and there might be some things you don't even realise you need until you get out of the shower at a hostel and realise your tiny face towel won't shield your dignity at all.
