Ermioni is a small, working harbour on the eastern shoulder of the Peloponnese, tucked into its own little peninsula rather than sprawling along a seafront. It has none of the bustle of a big island port -- boats tie up close to the cafes on the quay, and you can watch your ferry come in from a table with a coffee in front of you. The crossing to Piraeus runs up through the sheltered waters of the Argolic and Saronic gulfs, so it is generally a calm ride rather than an exposed open-sea one, though conditions can still turn lively when the meltemi is blowing hard in summer.
The spread between the fastest and slowest crossing times on this route is wide, which usually comes down to differences between high-speed and conventional vessels, and how many other calls a given sailing makes along the way. If timing matters to you -- a same-day return to Athens, or a tight connecting flight -- check the specific sailing you book rather than assuming the shortest published time applies across the board. This is a route well suited to people splitting a trip between Athens and the Peloponnese, or using Piraeus as a base while day-tripping down to Ermioni.
