Well it has taken some time but, eventually, we have a seasonal shuttle bus from Lamezia Airport along the Tyrrenian Coast all the way north to Praia A Mare with many stops along the way on the SS18 including Belvedere Marittimo, Diamante, Cirella, Grisolia, Santa Maria del Cedro, Scalea & Tortora.
The service runs twice in both directions every day including Sundays and bank holidays. The fare to Scalea is €7.20 (€8.60 to further stops and the route ends in Praia a Mare).
The early bus will get you to Lamezia airport by 6.15 am if you have an early flight out and you can find the full timetable here:
