Traveling alone to Portugal in July for 18 days and want to see something (authentic, culture) of Spain, but only have 2 days. this is my first time traveling alone....
Hi Theresa. I answered your question when you posted it on Sunday. Perhaps you haven't seen my reply? Here it is again
Portugal is quite a big country and you haven't said where you'll be based, which does make a difference.
There are mountains between Portugal and Spain which cause problems with train journeys.

Whilst it is possible to take the bus from Lisbon to Madridit's a pretty long journey. So I'd suggest you get to Faro (an interesting town in its own right) and then take the bus to Seville , a journey of only 1.5 hours.
Here's the official site for train times, details and fares (in English) within Portugal:
And routes, times, details, fares and online booking (if you wish) for long-distance buses within Portugal:
