I am hoping to join my friend in Leon to continue with her toward Santiago de Compostela. However, I am not sure how best to get to Leon. I am hoping to fly from London around Sunday 1st August and return on the 12th August. Which airport should I fly in and out of, and how do I then get to Leon. I will then have to return to the airport from somewhere further along, is it easy to get transport from different points along the way?
