Serifos and Kythnos sit close together in the western Cyclades, and the short hop between them is one of the more relaxed inter-island crossings you'll find in the group. Livadi, the port on Serifos, is a working harbour a few minutes below the hill-town, with tavernas along the waterfront where you can watch the boats come and go. On the Kythnos side you land at Merichas, a low-key port with a beach right by the quay, useful if you've got time to kill before a bus or taxi up to Chora. Because the two islands sit in the lee of each other, the crossing is generally sheltered rather than exposed, though a stiff meltemi in high summer can still put a chop on the water. Check the schedule box above for the latest confirmed dates before you travel.
Sailing frequency builds through the summer and eases back in the shoulder months either side of it -- see the month-by-month table below for how service actually breaks down across the year. It's a route that suits island-hoppers stringing together a western Cyclades itinerary rather than a fixed day-trip, since the crossing itself is quick and the connecting timetables at both ends tend to be generous in high season.
