The track spanned approximately 6 to 8 kilometers across the narrowest point of the Isthmus.
Ships were placed on specialized, wheeled frames to be hauled overland by teams of men or animals.
The name 'Diolkos' is derived from the Greek words 'dia' (across) and 'helko' (to haul or draw).
The invention of the track is attributed to the Corinthian tyrant Periander.
The width of the track varies between 3.4 and 6 meters to accommodate different vessel sizes.
The limestone blocks were specifically cut with parallel grooves to prevent carts from slipping off the track.
Historical records indicate the track was still being used during the Roman era for moving naval fleets.
Visible sections today are located near the western entrance of the Corinth Canal in Posidonia.
The track was designed to handle a gradient of up to 1.5% in certain sections.
The Diolkos is an ancient limestone-paved track constructed in the 6th century BCE to transport ships across the Isthmus of Corinth. It functioned as an early precursor to the canal system, allowing vessels to bypass the dangerous voyage around the Peloponnese peninsula. The track features deep grooves cut into the stone, which served as a guide for the wheeled vehicles carrying the ships. This strategic infrastructure remained in intermittent use for over 650 years, primarily for military and commercial purposes. Much of the site was destroyed or submerged during the construction of the modern Corinth Canal in the late 19th century. Today, remaining segments are visible along the canal's edge, highlighting the ingenuity of Archaic Greek engineering.

Bring binoculars to get a better view of the track details from the vantage point above the canal.
Combine your visit with a trip to the nearby archaeological site of Ancient Corinth.
Wear sturdy shoes as the area near the canal can be uneven and rocky.
Do not attempt to climb down into the active canal walls; stay on the designated viewing paths.
