We are planning a trip to Spain for 13 days in June/July 2017. We are hoping to go to Barcelona, Seville, Granada and Madrid. Any advice how many days in each and which order. We can fly into Madrid and out of Barcelona or the other way around. Can we get everywhere by train?

Can you get everywhere by train?
Seville - Granada , bus or car
Granada- Madrid, the line has been worked on, might be fixed by June.

The rest , yes.

How long to stay depends on your interest and tolerance for hot weather.
Granada 2 , Sevilla 3, Barcelona 3 -4 ( beach time), Madrid 3-4 ( day trip).??

Uff! You really want to go to Seville in July??? Sorry, but pls reconsider, many other places in Spain!

I know it's hot in late June/early July in the Seville region. Is it that unbearable that we should look to go elsewhere?

" Is it that unbearable that we should look to go elsewhere?"

Good grief, of course not.

Don't change your travel plans because of other's inability to deal with the weather.

Wake up early, take a siesta, go out late, walk on the shady side of the street.

"Feel the rhythm", like the Jamaicans say and you will be fine.

asproul, we were in Seville in July August and it was really really hot but that's the only time we could go so we went. You don't want to be outside in the heat of the day (like from 2 - 7) and definitely seek out shade wherever you go, but it won't ruin your trip if that's what you're worried about. It was still my 13 year old's favorite city. https://rovingrichards.com/travel/spain-2016/sevilla/ (oh, and I highly recommend that apartment too!)
