The conical rough stone tower sits on Cape Susaki on the Gulf of Megara a few miles east of the eastern entrance to the Corinth Canal. The old name for the cape is Sparta Point. The light guides westbound shipping into the canal. The green beacon is visible 12 miles ( 19.3 kilometers). The lighthouse sits in a large industrial area and is accessed via a rough dirt road that winds through the industrial complex. The interior is not open to the public but the beach at the lighthouse is a popular spot with fishermen.

The 1916 Mediterranean Pilot listed the light as fixed red and visible 8 miles (12.9 kilometers) indicating it was probably a sixth-order beacon. In 1990s the light was green and exhibited from a small skeleton tower a few feet west of the lighthouse. Recently, it was returned to the tower. The windows of the dwelling are barred to prevent entry and vandalism. On the east side of the lighthouse is the old well. The lighthouse underwent renovations in 2008-2009. Nearby is an excavated sanctuary to Poseidon and to the west is the site of the Isthmian Games, part of the four year cycle of the ancient Olympiad.

There is also an active saltworks nearby that dates from antiquity. The saltworks sulfurous smell mingles with the tangy tidal aroma at the lighthouse. Sousaki is the name of an extinct volcano on which the region sits. The area has been studied extensively for its geothermal activity.
