The main archaeological zone at Ancient Corinth covers the Roman-era city built over its earlier Greek predecessor. The site encompasses the agora (forum), the Temple of Apollo, the Glauke and Peirene fountains, the Lechaion Road, and numerous smaller structures — all within a compact area that can be covered on foot in a thorough morning.
Entry is combined with the on-site museum. The ticket office is at the site entrance in the modern village of Ancient Corinth; from there, paths lead through the ruins in a rough circuit. Most visitors spend two to three hours here. The site is open year-round and is shaded in parts, but the midday sun on the agora plateau can be brutal in summer — go early or late.
