• Submersible bridges at each end, by the harbors of Isthmia and Poseidonia, which drop below the water so boats can cross
• Bungee jumping at the Isthmus, if your visit lines up with it, is a show kids can watch from the bridge
• Remnants of the Diolkos lie beside the canal, the ancient stone trackway ships were towed along before it was dug

The Corinth Canal is a 6.3 km channel through the Isthmus of Corinth, finished in 1893, joining the Gulf of Corinth to the Saronic Gulf. Its rock walls rise up to 90 m, almost vertical.

From the bridges above, kids look straight down to the water, and with luck they see a ship pass through a gap only 24.6 m wide.
