Iraklia and Koufonissi sit close enough together in the Small Cyclades that the crossing barely gives you time to settle into a seat before the next harbour comes into view. Both islands are tiny, low-key, and largely free of cars, so this is one of the shortest and calmest hops in the Cyclades -- sheltered water for most of the year rather than the open swell you get on the bigger island-to-island runs further north. Check the schedule box above for the latest confirmed dates and departure times.
Because this is a short inter-island hop rather than a mainland connection, sailings are modest even at the height of summer, with a single daily departure typical through the season and fewer options once the shoulder months arrive. It is worth double-checking timings a day or two ahead, since a route this size can shift with weather or operator planning.
