“Set amid some of the most dramatic coastal scenery on the planet, these five ingeniously constructed fishing villages can bolster the most jaded of spirits. A Unesco World Heritage Site since 1997, Cinque Terre isn’t the undiscovered Eden it once was but, frankly, who cares? Sinuous paths traverse seemingly impregnable cliff sides, while a 19th-century railway line cut through a series of coastal tunnels ferries the footsore from village to village. Thankfully cars were banned over a decade ago.” – Lonely Planet
While it is possible to do it in a day I would recommend 2-3, especially if you are a hiker.
Head to Pisa on your way to Florence or up to Genova, one of Italy’s most underrated cities.
