i am arriving into madrid about 11 am on a friday....do i have time to get to roncevalles that day or do i stay the night at Pamplona , then next day to Roncevalles? also do i take a subway (is that the metro?) from Midrid airport to ? and then get what bus? would like a fast but inexpensive way to get there other than flying which is I assume is more expensive. Also what is the big deal of starting at roncevalles...wouldn't it be easier to just start at pamplona...or am I missing something i shouldn't ....many questions !
