Why visit: One of Greece’s most striking engineering landmarks — a narrow, scenic canal cutting through rock connecting the Gulf of Corinth and the Saronic Gulf. Tip: Great stop for photos — plan for a short visit (30–45 mins) and maybe coffee at the viewpoint.
Why visit: A dramatic hill-top fortress dominating the area above Corinth with sweeping views and rich history across centuries. Lots of cute little shops as well. Tip: Best visited in daylight; allow 1–2 hours for the climb and exploration.
