The Via dei Cavalleggeri takes its name from the cavalrymen who patrolled the coast to defend against sea attacks, curb smuggling, and prevent disease spread by intercepting infected sailors. Its history predates the Grand Dukes, with open-air archaeological sites showcasing Etruscan tombs and remnants of Populonia, a major Etruscan and Roman city near the Gulf of Baratti. This route traverses diverse landscapes, blending wild cliffs, Mediterranean maquis, and lush holm oak woods, creating stunning views of the sea and the Tuscan archipelago, including Elba. The circular trail begins at Cala Moresca in Salivoli, passing scenic coves like Buca delle Fate. The return climbs through shaded holm oak forests, completing an 18 km hike with an elevation gain of 595 meters. Rated moderately difficult due to its length rather than technical challenges, the hike can also begin from Populonia.
