The Man in Seat Sixty-One

I also like seat61.com for train travel tips - that man is a genius, especially European train travel.

Basically you need to go back and study tgat website. Seat61.com also discusses which countries are pass friendly countries.

Follow the advice about seat61.com, use it to have an idea how to plan. More than useful.

I always recommend [Wikivoyage](http://wikivoyage.org) and [Seat61](http://seat61.com) for lots of helpful information!

Seat61 may have some guidance on trying to do these international routes

You may find this website helpful.

I found that https://www.thetrainline.com was very helpful finding routes and timetable for trains (and buses). But, I typically buy directly from Renfe, Iryo, or Ouigo since it's typically cheaper. Here's more info: https://www.seat61.com/train-travel-in-spain.htm
