This small bay sits between the Ligurian Sea and the Tyrrhenian Sea to the north of the peninsula, which forms much of the town of Piombino.
Baratti stands on the Tyrrhenian coast, at the foot of Populonia, which is 1.5 km away, 12 km from Piombino, 15 from San Vincenzo, and about 80 km from Livorno in the north and Grosseto in the south.
