This is a day trip from Madrid . A visit to Escorial is usually included with a trip to "Valley of the Fallen". We found this stop to be very interesting . The monestary is a deep dive into to the History of the Kings of Spain. Their final resting places adorn the walls of the crypt rooms. The frescos and ornate crypts are amazing . On the darker side is the Royal Rotting Room .
Travelled Granada to Cordoba. Pleasant station café. Make sure you leave at least 30 minutes to clear unexpected security where everyone has to put there bags through scanner and then queue again for single person to check tickets. No prior warning that this happens. Surprising that there were no refreshments on board given that train continued onto Seville. Train ok but the whole experience not great. Probably use the bus next time.
Horrible is an understatement. Non-existent, horrible, disrespectful service. I have never seen anything like this in the world. The worst imaginable urban transport.
