Sifnos and Kythnos sit close together at the western edge of the Cyclades, and the short hop between them is one of the more relaxed inter-island links in this part of the Aegean. Sifnos's boats use Kamares, a modest working harbour a short drive below the hilltop town of Apollonia, while on Kythnos ferries come in at Merichas, a small bayside village that serves as the island's main hub for shops, rooms and tavernas. Sheltered to a degree by the surrounding islands, the crossing is generally gentler than routes that face open water, though a strong summer meltemi can still stir it up for an hour or so.
Check the schedule box above for the current confirmed dates, since operators file each season in stages and add sailings as the summer builds. Through the busiest weeks you can generally count on a handful of crossings most days, easing back to a lighter but still workable service either side of peak season -- enough to plan a day trip or a same-day onward connection without too much waiting on the quay.
