The historic ruin of Ancient Corinth is one of the best and easiest day trips you can take from Athens.
We actually enjoyed this more than the Acropolis, which is extremely crowded with tourists. Corinth is a lesser known place to see some amazing ruins and artifacts, and it used to be one of the major cities of classical Greece.
For Christians, Corinth is especially interesting because you can walk in the footsteps of the Apostle Paul, who spent 18 months there as a missionary, and famously wrote the letters of First and Second Corinthians.
