To stay just fit, but also to move easily through the localities of the coast, we recommend renting a bike from RE: Service at the Marina Cala de’ Medici in Rosignano. From Castiglioncello you can smoothly cycle up to Rosignano Solvay, the white beaches of Vada (through a cycle track) and even given the linear and flat land to Marina di Cecina, with its beautiful pine forest parallel to the sea. The most trained will find something interesting into facing the paths of the surrounding hills, a widely effort paid off by panoramic views, that on clear days range as far as Corsica island.
