Leaving Iraklia usually means heading back to Naxos, the big island that connects the Small Cyclades to the rest of Greece. After a few days of empty paths and quiet coves, Naxos feels like a city: a busy port town, long sandy beaches on the west coast, mountain villages inland, an airport just outside Chora and ferries to Piraeus, Paros, Mykonos and Santorini.
The boat that makes this link is the Express Skopelitis of Small Cyclades Lines, a small conventional ferry that shuttles between Naxos and the Small Cyclades. Ferryhopper describes it as calling at Iraklia and Schinoussa on its run between Naxos and Koufonisia, and on its outbound leg on 12 August 2026 it took 1 hr 30 min from Naxos to Iraklia, with fares from €7. We do not have a timed sailing in this direction, so we cannot tell you when it leaves Iraklia on a given day.
Our older route data also lists Blue Star Ferries and Seajets on this crossing. Blue Star's larger ships do serve the Small Cyclades, but we found no dated departure to confirm either company between Iraklia and Naxos, so we have not included their times or fares. If one of them appears in the booking box for your date, treat it as a welcome extra option.
The practical advice is simple: book the boat before you book your last night on Iraklia, and if you have a flight from Naxos or a Piraeus ferry afterwards, leave a buffer of a day. Small-boat schedules shift with the weather, and there is not always a second sailing to fall back on.
