Spetses and Poros sit at opposite ends of the same stretch of the Saronic Gulf, and the crossing between them is one of the shorter island-to-island hops you'll find in Greece. Spetses itself is largely car-free, its harbour lined with neoclassical mansions and horse-drawn carriages rather than traffic; Poros, tucked in against the Peloponnesian coast behind a narrow strait, has a pine-covered hillside town that rises steeply from the water. Neither port is a major terminal, so boarding tends to be straightforward and unhurried compared with the bigger island gateways further out in the Aegean. Check the schedule box above for the current confirmed sailing dates, since operators file each season's timetable in stages rather than all at once.
Expect the timetable to thin out well before and after the height of summer, when the route runs at its fullest -- several sailings a day at that point, dropping back to a single daily crossing once the season quietens. Both companies use fast catamaran-type vessels on this stretch, which is part of why the quoted journey times vary as much as they do; a direct sailing is close to the shorter end, while a boat that calls at other Saronic ports on the way will take nearer the two-hour mark.
