Route: Via Verde del Mar (Benicàssim - Oropesa del Mar, Spain)

The Vía Verde del Mar (Greenway of the Sea) runs along the wild and natural coast between Benicàssim and Oropesa del Mar, where the Sierra de Oropesa range of hills meets the sea. The highlight of this greenway is the way in which the old railway line has left its mark on the rugged landscape in the form of magnificent engineering works such as deep cuttings, a long illuminated tunnel, metal bridges... 

It's a perfect place to run.
