Trains in Spain
We took hi-speed Renfe trains between Sevilla, Málaga, and Granada.
The booking process online was straightforward enough. We booked all of them in advance so we could pick good times and select our seats.
Two of our three trains were delayed—I think the longest wait was another 30–45 minutes, so not too long.
Every station had security, but it was very light and just consisted of a metal detector and putting our bags through a machine. No taking electronics out, no taking off shoes, etc.
All of the stations had at least a little cafe from which to grab something to eat, which was nice.
Overall, I’d definitely recommend taking the hi-speed trains to get around! They are slower than flying but more convenient in just about every other aspect.
