We're looking to travel from Bilbao or San Sebastian to Grenada. Any suggestions? I'm looking at a really early flight on Vueling, but would consider Train. Thanks!
I don't like to fly unless I have no choice, so I would look at the train options first on the Renfe website.
There is also one train a day at 7am, but it requires a transfer in Madrid from Chamartin station to Atocha station, total journey time around 9 hours.
Alsa Bus has a departure daily at 0900, transfer at Madrid, journey time 10 hours 30. (and also an overnight departure at 2am!)
Assuming you mean Granada, rather than an island in the Carribean!!
So no wonderful land alternative, but then driving would take 8 to 9 hours without stops- which makes bus and train quite reasonable.
