overnight train

The only night routing I see is a convoluted one taking 15 hours. You change trains in Madrid and in Seville. There's a 6-hour layover in Seville (from 12:10 AM till 6:30 AM--sheer misery). I assume you'd have to book the trip in segments since it's such a sub-optimal mash-up. I think you need to look at other options.

Vueling has non-stop flights from Barcelona to Granada with both evening and early-morning options. Check skyscanner.

Is there a night train from Barcelona to Granada? I can't find it.

The night train that was operated by Trenhotel from Barcelona to Granada has been out of service for some time.

They stopped the overnight train when work began on the rail line to Granada. I doubt it ever returns.

The easiest way to get from Barcelona to Granada is to fly.

Indeed, it hasn't been a night train to Granada for years! Right now, if I'm not mistaken, there are two fast AVE trains departing at 8ish in the morning and reaches Granada at 5-6ish -including one change in Antequera (?)- and another one departing at 3ish pm reaching Granada before midnight. Check out the train operator, Renfe for specific details.

Thanks so much - no wonder I couldn't find the night train! That's sad - I love overnight trains.
