Nea Makri is linked with Marathonos Avenue (GR-53) that ends at Marathon to the north, and GR-83 to the north. Other main streets include Poseidonos Avenue.
The area was once known as Plesti, but following the 1922 Greek military disaster in Asia Minor and the subsequent repatriation of Greeks from the town of Makri, it was renamed Nea Makri (New Makri).
The Penteli mountains that are covered with forests lie to the west and southwest while farmlands are within Petalies Gulf and to the north except for the downtown part of Nea Makri. Beaches cover the eastern part and restaurants, hotels, and tavernas cover the area within the shoreline.
