Split to Seville

Does anyone know the best route to get from Split to Seville?

I was thinking prob the only way was to fly to Italy then to Seville. Or maybe if there are any ferries to Italy then fly from there.

Thanks for any help.

Well, best would be to do a Stopover somewhere.
By Ground travel you would have to take the Ferry to Ancona, then from there the Train to Milano,
then by night Train to Barcelona and then by Train to Sevilla.
This would easily leave you the option for a day in Barcelona or Milano.
