PÓROS TOWN rises steeply across the western half of tiny volcanic Sferiá, a landmark clocktower at its summit. There’s a two-room archeological museum on the waterfront (Tues–Sun 8.30am–3pm; €2) whose local finds will fill a spare half-hour, but otherwise few sights. This is a place to eat, drink, shop and watch the world go by. Away from the waterfront you’ll quickly get lost in the labyrinth of steep, narrow streets, but nowhere is far away and most of the restaurants reasonably well signed. For a fine view over the rooftops and the strait, climb up to the clocktower (signed Roloï) – the tower itself is structurally suspect and fenced off, but you can still enjoy the outlook.
