Budget Travel - Travelling in Spain

Hi, would anyone advice on the best way (and cheapeast) to get to Santiago de Compostela (or nearby) from Madrid.
Thanks for the help.

There is a daily Talgo train, taking about 7 hours and costing €18.70 if you book far enough in advance, or a slower overnight train with beds starting at €29.20 in advance. You can find and book this on renfe.es . Ryanair from MAD to SCQ is €10, but door-to-door it is likely to work out more expensive (card fees, check-in fees, baggage fees, transport to/from airports), and a lot less pleasant than the train. Bus is also an option, though the fares I can find on Alsa.es for this route are not competitive.

Hope this helps.
